Hi,I'm trying to use the TFM (Trusted Firmware M) example application from the B-U585I-IOT02A board. On first attempt the application compiled, flashed (via TFM_UPDATE.sh) and runs. But now I want to make changes to the system and after compiling the...

Hi,We are using an STM32H753 (revision V) and using the bank swap functionality to implement a firmware update system. To do this we need to write to the option bytes to toggle the bank swap bit.This process works but we have noticed that when the cu...

Hi,The CRC function of the flash module in the STM32H753 is documented as using the polynomial 0x04c11DB7. If I use this module to calculate a CRC over 128 bytes all set to zero I get a non-zero answer (0x11e66c62) so it must also be using an initia...

Hi,Although not specified in the reference manual it looks like the CRC process within the FLASH module (see section 4.3.12) has to have start and end addresses aligned to possibly the CRC_BURST size (I've only tried 128 byte bursts so far). If not a...

Using an STM32H743Zi I'm trying to receive 32bits of data from two SPI interfaces triggered at the same time from an external GPIO at a fairly high rate e.g. ~200kHz. Trying to use double buffered DMA receive.I started by trying to get an external GP...
