HISTM32F723 is used in custom electronics. USB CDC device (virtual com port) high speed.All was working reliably for the past year or so.Last CubMx update (6.4.0) broke the USB interface completely – when plugged in, the PC won’t recognize the hardwa...

HiI am using the STM32F723 to read FPGA with the (notorious) QSPI interface in a custom board.The QSPI is configured to indirect read mode, 4 bits, using DMA.The issue is that the first nibble is not read. All other bytes are as expected.The Errata s...

HiI am using the QSPI to interface FPGA.The setup includes STM32F769I-EVAL board wired to MAX10 evaluation board.The QSPI is configured to indirect mode, data phase only. I was able to read data from the FPGA, control clock speed and set number of by...
