Hello All,I have a certain STM32H7 that I can't erase sector 0 using STM32CubeProgrammer.I think it is because PROT_AREA_START1 and PROT_AREA_END1 are not correct. I am trying to get back to default values of PROT_AREA_START1 =0xFF (0x0800ff00)PROT_...

Hello All, I am trying to get Full Duplex I2S working with a STM32H7 and a PCM3168A.The STM has 2 SAI blocks (SAI1 A/B) (A in master mode and B in synchronous slave) for sending data to the PCM for the DAC part of the PCM. I use this to transmit 4 Mo...

Hello All,I am having an issue interfacing an SD card to the STM23H7.I am using the SDMMC1 with 4 bit wide bus. When testing HAL_SD_WriteBlocks , I can write and read from the card successfully at various lengths (different number of blocks). But I...

Hi Chloe,The results are the same after reconnects/resets/power cycling All security bits are disabled.nWRPx = 1I attached a log, where I connect, and then try a full chip erase. Thanks,Trevor

Some (perhaps useful?) Data: I had tested about 10 of these OVEVO Cards. and the errors would happen for about 3 in 10. Sometimes I could get get one of these "non-working" cards to work again for a short time after a reformat. (and perhaps a cooldow...

These errors no longer occur when I use a more expensive SanDisk microSD. I was using a OLEVO microSD from AliExpress. So attributing this to bad sdcards.-Trevor

I found out my issue - I had not enabled "External Synchro Out" in the .ioc configuration on the master , (SAI1). After enabling that the slaves began to work.I also ended up switching from SAI4 to SAI2 for the slave. Because only the BDMA was atta...

Hi Tesla, Thanks for the reply.So to be clear the HAL_SD_WriteBlocks() function does not block until the write is finished? I would expect that to be the case for sure with HAL_SD_WriteBlocks_IT and HAL_SD_WriteBlocks_DMA of course. I'm not sure w...
