I also tried to put an echo in the USB received function (sure to have the same IT priority) to send the data received back. I got the same result BUSY:static int8_t CDC_Receive_HS(uint8_t* Buf, uint32_t *Len) { /* USER CODE BEGIN 11 */ USBD_CDC_...

Ok, so I created a timer with the same interrupt priority and I call the function CDC_TRANSMIT_HS in the handler of this timer.The result is still the same, when I use another peripheral I get a busy error from the CDC_TRANSMIT_HS#include "usbd_cdc_i...

Two instances of OCTOSPI not working simultaneously on STM32H7A3ZGT

Application doesn't work when loaded through USB DFU

Can I manually update parts of my screen with touchgfx?

HAL_UARTEx_ReceiveToIdle_DMA only fills the first carater of my array
