I have a board using STM32F103CBT6 chip. After flashing the board once (through CubeIDE v1.14.0 with ST-Link v2) I cannot flash it again and keep getting the message "No target found". Here's a snapshot of the chip circuit: When I power up the boa...

I'm trying to read and write SPI bytes from an STM32F446RE chip with DMA. The STM32f4 is the slave and a RPi is the master. The first SPI read works fine (data read into buffer starting at index 0), but subsequent reads have the data starting at in...

I can use the Motor Pilot ok but when I try to connect with the motor profiler I see a momentary connection when left in "polling" mode where the B-G431B-ESC1 board flashes on screen, then the board disconnects and the image disappears. Here's the l...

I'm trying to use the dev kit to run a BLDC motor in sensorless mode using the default MCW project. When the motor starts up I hear a high pitch chirp and then the firmware repeditively tries to spin the motor which results in more periodic chirps. ...

I generated some code with the default "Electronic speed control on B-G431B-ESC1 kit" project in Motor Control WorkBench. Then when I flash the default code I get a HardFault when calling `__HAL_FLASH_PREFETCH_BUFFER_ENABLE()` in `HAL_Init()`:int m...

The issue was that I did not configure PA13/PA14 before flashing the first time. Now that I configured the pins properly the board can flash multiple times. I'll also add a NRST pinout for this board in case this happens in the future.

The Pi sends 4k bytes to the STM32, then the STM32 responds with 6 bytes. I'll try to get some waveform captures to post here.

Thanks for your comment. To answer your questions:DMA is set to one shot for rx and txThe reads on the STM32 side are off by 1 if I don't reset the SPI peripheral with the code above. The reads on the RPi side look to be fine with no peripheral res...

Will do, thank you!

I tried regenerating the project and was able to pass this init step without hardfault. The only other thing I did was update STLink. Not sure why the problem went away but thank you.
