Hi,when I increase the size of the ThreadX trace buffer above 30k the RTT output is not working anymore (Below 30k RTT works fine). static uint8_t trace_buffer[1024*64] __attribute__((section(".trace"))); My guess is that the RTT viewer can't find th...

I am currently trying to figure out at what byte the slave sends a NACK during an I2C master write transfer.When the slave sends the NACK after X bytes the error callback is called. Inside the error callback I am having trouble finding out at what by...

Hey there,I am using the CubeProgrammer API (2.17.0) to flash a STM32U545 MCU over USB DFU with a new firmware.When doing so a write error occurs (downlaodFile(...) returns CUBEPROGRAMMER_ERROR_WRITE_MEM (-10)) when flashing a new hex file (when usin...

Hi,I am trying to connect to a STM32H523RET MCU via SWD using a J-link Debugger (CubeProgrammer v2.17.0).Reading the Product ID fails, so I get asked to select the MCU manually.Unfortunately the list does not contain any STM32H52x MCU But when I am t...

Hey there :)I am having trouble running the nucleo (NUCLEO-U5A5ZJ-Q) as an I2C slave where read/write sizes are unknown (only known by master)For the configuration I am using CubeMX and most of the time the slave is working quite fine. However someti...

Thank you. The DMA channels have FIFO buffers (8 bytes in my case). And and the GPDMA_CxSR.FIFOL[7:0] bits contain the remaining write beats of the FIFO. The problem I have now is that the HAL lib resets the fifo before calling the abort callback ......

Thanks, after adding a mass erase before the file download it was working.It seems that the erase flag of the downloadFile() is ignored or not working...CubeProgrammer::dfuDeviceInfo* dfu_list = nullptr; int count = CubeProgrammer::getDfuDeviceList(&...

Thanks, I can confirm this worked for me. Now also the connection in the CubeIDE works as well.

@Imen.D I have also tested to connect via J-Flash, which works fine.Could it be that this is a CubeProgrammer issue?(Connecting to a STM32U545 device works also with the CubeProgrammer)Regards,John
