# RP2350 GPIO Coprocessor Blink - Detailed Documentation
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
This is a **bare-metal assembly program** for the **Raspberry Pi RP2350** microcontroller that demonstrates the use of the **ARM Cortex-M33 coprocessor interface** to control GPIO pins. Unlike traditional GPIO control using direct memory-mapped register writes, this version uses the RP2350's **hardware GPIO coprocessor (CP0)** with **MCRR (Move to Coprocessor from two ARM Registers)** instructions.
|
||||||
|
|
||||||
|
The program blinks an LED connected to **GPIO16** with a 500ms on/off cycle using the specialized coprocessor instructions for high-performance GPIO operations.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## What Makes This Special?
|
||||||
|
|
||||||
|
### Traditional GPIO Control vs Coprocessor Control
|
||||||
|
|
||||||
|
**Traditional Method (Direct Register Access):**
|
||||||
|
```assembly
|
||||||
|
LDR R0, =SIO_BASE ; Load SIO base address
|
||||||
|
LDR R1, =GPIO16_BIT ; Load GPIO bit mask
|
||||||
|
STR R1, [R0, #GPIO_OUT_SET] ; Write to memory-mapped register
|
||||||
|
```
|
||||||
|
|
||||||
|
**Coprocessor Method (This Implementation):**
|
||||||
|
```assembly
|
||||||
|
MOVS R4, #16 ; GPIO pin number
|
||||||
|
MOVS R5, #1 ; Value to write
|
||||||
|
MCRR p0, #4, R4, R5, c0 ; Single coprocessor instruction
|
||||||
|
```
|
||||||
|
|
||||||
|
### Advantages of the Coprocessor Approach:
|
||||||
|
1. **Faster execution** - Single instruction instead of multiple memory operations
|
||||||
|
2. **More atomic** - Less chance of race conditions
|
||||||
|
3. **Hardware-accelerated** - Direct hardware interface
|
||||||
|
4. **Cleaner code** - No need to manage bit masks and base addresses
|
||||||
|
5. **RP2350-specific** - Takes advantage of advanced features
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Hardware Requirements
|
||||||
|
|
||||||
|
- **RP2350-based board** (e.g., Raspberry Pi Pico 2)
|
||||||
|
- **LED** connected to **GPIO16** (or use built-in LED if available)
|
||||||
|
- Optional: Current-limiting resistor (typically 330Ω - 1kΩ)
|
||||||
|
- **USB cable** for programming
|
||||||
|
|
||||||
|
### GPIO16 Connection
|
||||||
|
```
|
||||||
|
RP2350 GPIO16 ----[330Ω]----[LED]---- GND
|
||||||
|
(Resistor) (Anode to GPIO, Cathode to GND)
|
||||||
|
```
|
||||||
|

|
||||||
|
|
||||||
|
## Technical Details
|
||||||
|
|
||||||
|
### Coprocessor Interface
|
||||||
|
|
||||||
|
The RP2350 implements a **custom GPIO coprocessor (CP0)** accessible through the ARM Cortex-M33's coprocessor interface. This is documented in the RP2350 datasheet.
|
||||||
|
|
||||||
|
#### MCRR Instruction Format
|
||||||
|
```
|
||||||
|
MCRR p0, #opcode, Rt, Rt2, CRm
|
||||||
|
```
|
||||||
|
|
||||||
|
Where:
|
||||||
|
- `p0` = Coprocessor 0 (GPIO coprocessor)
|
||||||
|
- `#opcode` = Operation code (4 for GPIO operations)
|
||||||
|
- `Rt` = First source register (GPIO pin number in R4)
|
||||||
|
- `Rt2` = Second source register (value in R5)
|
||||||
|
- `CRm` = Coprocessor register (c0 for OUT, c4 for OE)
|
||||||
|
|
||||||
|
### GPIO Coprocessor Operations Used
|
||||||
|
|
||||||
|
#### 1. `gpioc_bit_out_put(gpio, value)`
|
||||||
|
**Purpose:** Set or clear a GPIO output pin
|
||||||
|
**Encoding:** `MCRR p0, #4, R4, R5, c0`
|
||||||
|
**Parameters:**
|
||||||
|
- R4 = GPIO pin number (16 in our case)
|
||||||
|
- R5 = Output value (0 or 1)
|
||||||
|
|
||||||
|
**Example:**
|
||||||
|
```assembly
|
||||||
|
MOVS R4, #16 ; GPIO16
|
||||||
|
MOVS R5, #1 ; Set HIGH
|
||||||
|
MCRR p0, #4, R4, R5, c0
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 2. `gpioc_bit_oe_put(gpio, enable)`
|
||||||
|
**Purpose:** Set output enable for a GPIO pin
|
||||||
|
**Encoding:** `MCRR p0, #4, R4, R5, c4`
|
||||||
|
**Parameters:**
|
||||||
|
- R4 = GPIO pin number (16 in our case)
|
||||||
|
- R5 = Output enable (1 to enable output)
|
||||||
|
|
||||||
|
**Example:**
|
||||||
|
```assembly
|
||||||
|
MOVS R4, #16 ; GPIO16
|
||||||
|
MOVS R5, #1 ; Enable output
|
||||||
|
MCRR p0, #4, R4, R5, c4
|
||||||
|
```

## Memory Map & Register Addresses
|
||||||
|
|
||||||
|

|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Code Structure & Execution Flow
|
||||||
|
|
||||||
|
### 1. Vector Table (`.vectors` section)
|
||||||
|
```assembly
|
||||||
|
.section .vectors, "ax"
|
||||||
|
.align 2
|
||||||
|
.global _vectors
|
||||||
|
_vectors:
|
||||||
|
.word STACK_TOP /* 0x20082000 - Initial Stack Pointer */
|
||||||
|
.word Reset_Handler + 1 /* Reset Handler (Thumb bit set) */
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why `+ 1`?**
|
||||||
|
The Cortex-M33 uses the Thumb instruction set exclusively. The LSB (least significant bit) of function pointers must be set to 1 to indicate Thumb mode. This is automatically handled by the processor.
|
||||||
|
|
||||||
|
### 2. Stack Initialization
|
||||||
|
```assembly
|
||||||
|
Reset_Handler:
|
||||||
|
/* Initialize stack pointers for Cortex-M33 */
|
||||||
|
LDR R0, =STACK_TOP
|
||||||
|
MSR PSP, R0 /* Process Stack Pointer */
|
||||||
|
|
||||||
|
LDR R0, =STACK_LIMIT
|
||||||
|
MSR MSPLIM, R0 /* Main Stack Pointer Limit */
|
||||||
|
MSR PSPLIM, R0 /* Process Stack Pointer Limit */
|
||||||
|
|
||||||
|
LDR R0, =STACK_TOP
|
||||||
|
MSR MSP, R0 /* Main Stack Pointer */
|
||||||
|
```
|
||||||
|
|
||||||
|
**Cortex-M33 Stack Features:**
|
||||||
|
- **Dual stack pointers:** MSP (Main) and PSP (Process)
|
||||||
|
- **Stack limit registers:** MSPLIM and PSPLIM for overflow detection
|
||||||
|
- **Security feature:** Prevents stack overflow from corrupting memory
|
||||||
|
|
||||||
|
### 3. Coprocessor Access Enablement
|
||||||
|
```assembly
|
||||||
|
/* Enable coprocessor access - set CP0 to full access */
|
||||||
|
LDR R0, =0xE000ED88 /* CPACR address */
|
||||||
|
LDR R1, [R0] /* Read current value */
|
||||||
|
ORR R1, R1, #0x3 /* Set CP0 bits [1:0] to 11 (full access) */
|
||||||
|
STR R1, [R0] /* Write back */
|
||||||
|
DSB /* Data Synchronization Barrier */
|
||||||
|
ISB /* Instruction Synchronization Barrier */
|
||||||
|
```
|
||||||
|
|
||||||
|
**Critical Step:** Without this, MCRR instructions will trigger a **UsageFault** exception!
|
||||||
|
|
||||||
|
**Memory Barriers:**
|
||||||
|
- `DSB` - Ensures all memory operations complete before proceeding
|
||||||
|
- `ISB` - Flushes instruction pipeline to ensure new settings take effect
|
||||||
|
|
||||||
|
### 4. GPIO Pad Configuration
|
||||||
|
```assembly
|
||||||
|
/* Configure pad for GPIO16 */
|
||||||
|
LDR R3, =0x40038044 /* &pads_bank0_hw->io[16] */
|
||||||
|
LDR R2, [R3] /* load current config */
|
||||||
|
BIC R2, R2, #0x80 /* clear OD (bit 7) - enable output */
|
||||||
|
ORR R2, R2, #0x40 /* set IE (bit 6) - enable input buffer */
|
||||||
|
STR R2, [R3] /* store updated config */
|
||||||
|
```
|
||||||
|
|
||||||
|
**What this does:**
|
||||||
|
- Clears OD (Output Disable) bit → Allows pin to drive output
|
||||||
|
- Sets IE (Input Enable) bit → Enables input buffer for reading
|
||||||
|
- Preserves other settings (pull-ups, drive strength, etc.)
|
||||||
|
|
||||||
|
### 5. Function Selection
|
||||||
|
```assembly
|
||||||
|
/* Set GPIO16 function to SIO (Software I/O) */
|
||||||
|
LDR R3, =0x40028084 /* &io_bank0_hw->io[16].ctrl */
|
||||||
|
LDR R2, [R3] /* load current config */
|
||||||
|
BIC R2, R2, #0x1F /* clear FUNCSEL bits [4:0] */
|
||||||
|
ORR R2, R2, #5 /* set FUNCSEL = 5 (SIO) */
|
||||||
|
STR R2, [R3] /* store updated config */
|
||||||
|
```
|
||||||
|
|
||||||
|
**Function 5 (SIO):**
|
||||||
|
- Routes GPIO to software control
|
||||||
|
- Required before using coprocessor GPIO operations
|
||||||
|
- Other functions route to hardware peripherals (UART, SPI, etc.)
|
||||||
|
|
||||||
|
### 6. Pad Isolation
|
||||||
|
```assembly
|
||||||
|
/* Un-isolate the pad */
|
||||||
|
LDR R3, =0x40038044 /* &pads_bank0_hw->io[16] */
|
||||||
|
LDR R2, [R3] /* load current config */
|
||||||
|
BIC R2, R2, #0x100 /* clear ISO bit (bit 8) */
|
||||||
|
STR R2, [R3] /* store updated config */
|
||||||
|
```
|
||||||
|
|
||||||
|
**ISO bit:**
|
||||||
|
- When set (1): Pad is isolated from peripherals
|
||||||
|
- When clear (0): Pad is connected and functional
|
||||||
|
- Must be cleared for GPIO to work
|
||||||
|
|
||||||
|
### 7. Enable GPIO Output
|
||||||
|
```assembly
|
||||||
|
/* Enable output using coprocessor */
|
||||||
|
MOVS R4, #16 /* GPIO16 */
|
||||||
|
MOVS R5, #1 /* Enable output */
|
||||||
|
MCRR p0, #4, R4, R5, c4 /* gpioc_bit_oe_put(16, 1) */
|
||||||
|
```
|
||||||
|
|
||||||
|
**This is the first coprocessor instruction!**
|
||||||
|
- Sets the Output Enable (OE) bit for GPIO16
|
||||||
|
- Makes the pin drive its output value
|
||||||
|
- Uses coprocessor register c4 (OE control)
|
||||||
|
|
||||||
|
### 8. Main Blink Loop
|
||||||
|
```assembly
|
||||||
|
blink_loop:
|
||||||
|
/* Turn LED ON */
|
||||||
|
MOVS R4, #16 /* GPIO16 */
|
||||||
|
MOVS R5, #1 /* HIGH */
|
||||||
|
MCRR p0, #4, R4, R5, c0 /* gpioc_bit_out_put(16, 1) */
|
||||||
|
|
||||||
|
/* Delay ~500ms */
|
||||||
|
LDR R2, =2000000 /* 2M cycles */
|
||||||
|
delay_on:
|
||||||
|
SUBS R2, R2, #1 /* Decrement */
|
||||||
|
BNE delay_on /* Loop until zero */
|
||||||
|
|
||||||
|
/* Turn LED OFF */
|
||||||
|
MOVS R4, #16 /* GPIO16 */
|
||||||
|
MOVS R5, #0 /* LOW */
|
||||||
|
MCRR p0, #4, R4, R5, c0 /* gpioc_bit_out_put(16, 0) */
|
||||||
|
|
||||||
|
/* Delay ~500ms */
|
||||||
|
LDR R2, =2000000 /* 2M cycles */
|
||||||
|
delay_off:
|
||||||
|
SUBS R2, R2, #1 /* Decrement */
|
||||||
|
BNE delay_off /* Loop until zero */
|
||||||
|
|
||||||
|
B blink_loop /* Repeat forever */
|
||||||
|
```
|
||||||
|
|
||||||
|
**Delay Calculation:**
|
||||||
|
- 2,000,000 cycles at ~4-12 MHz boot clock
|
||||||
|
- Approximately 500ms per delay
|
||||||
|
- Total period: ~1 second (1Hz blink rate)
|
||||||

|
||||||
|
|
||||||
|
## Flashing Instructions
|
||||||
|
|
||||||
|
### Method 1: UF2 Bootloader (Easiest)
|
||||||
|
|
||||||
|
1. **Disconnect** the RP2350 from USB
|
||||||
|
2. **Hold the BOOTSEL button** on the board
|
||||||
|
3. **Connect USB cable** while holding BOOTSEL
|
||||||
|
4. **Release BOOTSEL** - Board appears as USB mass storage device
|
||||||
|
5. **Copy** `gpio16_blink.uf2` to the RP2350 drive
|
||||||
|
6. **Board automatically reboots** and starts running the program
|
||||||
|
|
||||||
|
### Method 2: OpenOCD with Debug Probe
|
||||||
|
|
||||||
|
If you have a debug probe (e.g., Raspberry Pi Debug Probe, CMSIS-DAP):
|
||||||
|
|
||||||
|
```bash
|
||||||
|
openocd -f interface/cmsis-dap.cfg -f target/rp2350.cfg \
|
||||||
|
-c "adapter speed 5000" \
|
||||||
|
-c "program gpio16_blink.elf verify reset exit"
|
||||||
|
```
|
||||||
|

## Debugging & Troubleshooting
|
||||||
|
|
||||||
|
### Problem: LED doesn't blink
|
||||||
|
|
||||||
|
**Check 1: Coprocessor Access**
|
||||||
|
- Ensure CPACR is set correctly
|
||||||
|
- Without this, MCRR triggers UsageFault
|
||||||
|
- Verify DSB/ISB barriers are present
|
||||||
|
|
||||||
|
**Check 2: GPIO Configuration**
|
||||||
|
- Verify FUNCSEL is set to 5 (SIO)
|
||||||
|
- Check OD bit is cleared (output enabled)
|
||||||
|
- Ensure ISO bit is cleared (pad connected)
|
||||||
|
|
||||||
|
**Check 3: Hardware Connections**
|
||||||
|
- LED polarity (anode to GPIO, cathode to GND)
|
||||||
|
- Current-limiting resistor present
|
||||||
|
- GPIO16 physically connected
|
||||||
|
|
||||||
|
**Check 4: Clock Speed**
|
||||||
|
- Boot clock may vary (4-12 MHz typical)
|
||||||
|
- Delay timing depends on actual clock
|
||||||
|
- Adjust delay constant if needed
|
||||||
|
|
||||||
|
### Problem: Build fails
|
||||||
|
|
||||||
|
**Missing toolchain:**
|
||||||
|
```
|
||||||
|
'arm-none-eabi-as' is not recognized...
|
||||||
|
```
|
||||||
|
Solution: Install ARM GNU Toolchain and add to PATH
|
||||||
|
|
||||||
|
**Missing uf2conv.py:**
|
||||||
|
```
|
||||||
|
python: can't open file 'uf2conv.py'
|
||||||
|
```
|
||||||
|
Solution: Ensure uf2conv.py is in `../../` relative to build directory
|
||||||
|
|
||||||
|
**Assembly errors:**
|
||||||
|
```
|
||||||
|
Error: bad instruction 'mcrr'
|
||||||
|
```
|
||||||
|
Solution: Ensure `-mcpu=cortex-m33` flag is used (M33 supports coprocessor)
|
||||||
|
|
||||||
|
### Problem: Board doesn't appear as USB drive
|
||||||
|
|
||||||
|
**Solution 1:** Try different USB cable (must support data, not just power)
|
||||||
|
**Solution 2:** Hold BOOTSEL earlier (before connecting USB)
|
||||||
|
**Solution 3:** Check USB port functionality
|
||||||

## Performance Analysis
|
||||||
|
|
||||||
|
### Instruction Cycle Counts (Approximate)
|
||||||
|
|
||||||
|
**Traditional GPIO Write (3-4 instructions):**
|
||||||
|
```assembly
|
||||||
|
LDR R0, =SIO_BASE ; 2 cycles
|
||||||
|
LDR R1, =GPIO16_BIT ; 2 cycles
|
||||||
|
STR R1, [R0, #offset] ; 2 cycles
|
||||||
|
; Total: ~6 cycles + memory latency
|
||||||
|
```
|
||||||
|
|
||||||
|
**Coprocessor GPIO Write (2 instructions):**
|
||||||
|
```assembly
|
||||||
|
MOVS R4, #16 ; 1 cycle
|
||||||
|
MOVS R5, #1 ; 1 cycle
|
||||||
|
MCRR p0, #4, R4, R5, c0 ; 1 cycle (hardware accelerated)
|
||||||
|
; Total: ~3 cycles
|
||||||
|
```
|
||||||
|
|
||||||
|
**Performance Gain: ~50% faster execution**
|
||||||
|
|
||||||
|

## Advanced Topics
|
||||||
|
|
||||||
|
### Extending to Multiple GPIOs
|
||||||
|
|
||||||
|
To control multiple GPIOs with coprocessor:
|
||||||
|
|
||||||
|
```assembly
|
||||||
|
; Blink GPIO16 and GPIO17 alternately
|
||||||
|
blink_multi:
|
||||||
|
; Turn GPIO16 ON, GPIO17 OFF
|
||||||
|
MOVS R4, #16
|
||||||
|
MOVS R5, #1
|
||||||
|
MCRR p0, #4, R4, R5, c0
|
||||||
|
|
||||||
|
MOVS R4, #17
|
||||||
|
MOVS R5, #0
|
||||||
|
MCRR p0, #4, R4, R5, c0
|
||||||
|
|
||||||
|
; Delay...
|
||||||
|
|
||||||
|
; Turn GPIO16 OFF, GPIO17 ON
|
||||||
|
MOVS R4, #16
|
||||||
|
MOVS R5, #0
|
||||||
|
MCRR p0, #4, R4, R5, c0
|
||||||
|
|
||||||
|
MOVS R4, #17
|
||||||
|
MOVS R5, #1
|
||||||
|
MCRR p0, #4, R4, R5, c0
|
||||||
|
```
|
||||||
|
|
||||||
|
### Reading GPIO with Coprocessor
|
||||||
|
|
||||||
|
The RP2350 also supports GPIO read operations:
|
||||||
|
|
||||||
|
```assembly
|
||||||
|
; Read GPIO state using MRRC (Move to ARM Registers from Coprocessor)
|
||||||
|
MOVS R4, #16 ; GPIO to read
|
||||||
|
MRRC p0, #opcode, R4, R5, c0 ; Result in R5
|
||||||
|
```
|
||||||
|
|
||||||
|
*(Exact opcode may vary - consult RP2350 datasheet)*
|
||||||
|
|
||||||
|
### Interrupt-Driven Delays
|
||||||
|
|
||||||
|
For production code, replace busy-wait delays with timer interrupts:
|
||||||
|
|
||||||
|
```assembly
|
||||||
|
; Configure SysTick for 1ms interrupts
|
||||||
|
LDR R0, =0xE000E010 ; SysTick base
|
||||||
|
LDR R1, =4000 ; Reload value for 1ms at 4MHz
|
||||||
|
STR R1, [R0, #4] ; SYST_RVR
|
||||||
|
MOV R1, #7 ; Enable + interrupt + clock
|
||||||
|
STR R1, [R0, #0] ; SYST_CSR
|
||||||
|
```
|
||||||
|
|
||||||

|

|
* DESCRIPTION:
|
||||||
|
* RP2350 IMAGE_DEF Block.
|
||||||
|
* A minimum amount of metadata (a valid IMAGE_DEF block) must be embedded in any
|
||||||
|
* binary for the bootrom to recognise it as a valid program image, as opposed to,
|
||||||
|
* for example, blank flash contents or a disconnected flash device. This must
|
||||||
|
* appear within the first 4 kB of a flash image, or anywhere in a RAM or OTP image.
|
||||||
|
*
|
||||||
|
* Unlike RP2040, there is no requirement for flash binaries to have a checksummed
|
||||||
|
* "boot2" flash setup function at flash address 0. The RP2350 bootrom performs a
|
||||||
|
* simple best‑effort XIP setup during flash scanning, and a flash‑resident program
|
||||||
|
* can continue executing in this state, or can choose to reconfigure the QSPI
|
||||||
|
* interface at a later time for best performance.
