# MCUZone AT32UC3B0256 mini development board
|
|
|
|
## Introduction
|
|
|
|
**The AVR32 is a high performance, low power 32-bit Atmel AVR
|
|
microcontroller.** This board support package supports the MCUZone
|
|
AVR32 mini development board (also known as the AVR32DEV1). The
|
|
development board uses the AT32UC3B0256 microcontroller.
|
|
|
|
|
|
|
|
Note: Unfortunately, the online link for the development board (both
|
|
MCUZone OR Aliexpress) doesn't work. I don't have access to the
|
|
schematic (OR Gerber information) for this development kit. I used a
|
|
multimeter to look for the connected pins. If you - the reader - do
|
|
have access to the schematic/pinouts, could you please reach out to
|
|
me?
|
|
|
|
This README is essentially a work-in-progress. I will try to map the
|
|
berg rows (J1 and J2) and document them as and when I further the
|
|
device driver base for the target.
|
|
|
|
If you feel like reaching out to me for questions pertaining to the
|
|
target development board, you can write to me: ramangopalan AT gmail
|
|

|
## Supported compiler
|
|
|
|
This BSP is built with the AVR32 GCC that comes with the Microchip
|
|
Studio. I am using the Microchip Studio version 7.0.2594. Make sure
|
|
that avr32-gcc.exe is visible on your command line. Add the binary
|
|
directory to you PATH. Yes, on Windows. Sorry :(
|
|
|
|
|
|
|
|
I use Git Bash (Windows) for compiling the RT-Thread system. Once you
|
|
set your path correctly, invoke Git Bash to query avr32-gcc.exe's
|
|
version. The output should look similar to this:
|
|
|
|
```bash
|
|
$ avr32-gcc.exe --version
|
|
avr32-gcc.exe (AVR_32_bit_GNU_Toolchain_3.4.2_435) 4.4.7

|
|
|
|
If you see this, you're all set to compile RT-Thread for AT32UC3B0256.
|
|
|
|
## Program firmware
|
|
|
|
### Step 1: download the RT-Thread codebase and navigate to bsp/avr32uc3b0.
|
|
|
|
```bash
|
|
$ cd bsp/avr32uc3b0/
|
|
```
|
|
|
|
### Step 2: build
|
|
|
|
```bash
|
|
scons -c
|
|
scons
|
|
```
|
|
|
|
### Step 3: flash
|
|
|
|
If everything went well, scons should have generated an elf file:
|
|
rtthread-uc3b0256.elf. Let us program the file. The program `atprogram'
|
|
comes with Microchip Studio. I didn't have to do much here. Just make sure
|
|
`atprogram.exe' is in your PATH.
|
|
|
|
```bash
|
|
atprogram -t atmelice -i jtag -d at32uc3b0256 program -f rtthread-uc3b0256.elf
|
|
```
|
|
|
|
Note that you should already see the on-board LEDs (PA7, PA8) blink if your
|
|
programming was successful. I use the Atmel ICE programmer. To access
|
|
msh, you'll need an FTDI breakout board. Connect the target board to
|
|
the FTDI breakout with jumper wires:
|
|
|
|
- GND (FTDI) to GND (development board)
|
|
- RX (FTDI) to J2, pin 10.
|
|
- TX (FTDI) to J2, pin 7.
|
|
|
|
## Running Result
|
|
|
|
The output information on serial port for `ps' the command should look like this:
|
|
|
|
```bash
|
|
0x000003c0 tidle0 31 ready 0x00000054 0x00000100 67% 0x00000009 OK
