Today after work I decided to get going with the STM32 Discovery board that I had bought a while back but never used. It’s a cheap board but it’s not quite friendly when it comes to inserting it into a breadboard.
After making the initial connections, I was able to start its bootloader and communicate through its USART1 serial port, which connects to my PC via a TTL->USB bridge (FTDI style).
Here’s the output from the stm32flash utility:
stm32flash.exe -b 115200 COM6 stm32flash 0.4 http://stm32flash.googlecode.com/ Interface serial_w32: 115200 8E1 Version : 0x22 Option 1 : 0x00 Option 2 : 0x00 Device ID : 0x0420 (Medium-density VL) - RAM : 8KiB (512b reserved by bootloader) - Flash : 128KiB (sector size: 4x1024) - Option RAM : 16b - System RAM : 2KiB
As you can see it’s not as equipped as the primary MCU I am using for developing DC2N5, but it’s something worth exploring so I am finishing the last bits of porting my framework to the STM32F100 family of MCUs 🙂
