USBH_MSC_Read Problem is Stuck in while Loop?

Hello USBH_MSC_Read function uses a while loop and USBH_MSC_RdWrProcess to USB mass storage.  while (USBH_MSC_RdWrProcess(phost, lun) == USBH_BUSY) { if (((phost->Timer - timeout) > (10000U * length)) || (phost->device.is_connected == 0U) ) ...

STM32F756VGT6 DFU USB not working

I have used DFU USB to program hundreds of STM32F7 devices over the past several years. It has worked reliably until the most recent batch of 200 boards using STM32F&56VGT6 devices. We had approximately a 10% failure of the DFU USB connection (USB no...

How does one design a circuit where an STM32H7 is never unrecoverable?

Per section 2.6 of RM0433 (https://www.st.com/resource/en/reference_manual/rm0433-stm32h742-stm32h743753-and-stm32h750-value-line-advanced-armbased-32bit-mcus-stmicroelectronics.pdf), when the STM32H7 boots up it latches the boot pin and then goes to...
