I am writing to an SD card using the Adafruit_Shield BSP library on the STM32L4R5ZI Nucleo board. I had it writing 10 values, from 0x00 to 0x09 but the second byte (with a value of 0x01) was getting corrupted as set to 0x00. I changed the array so ...

I am having trouble with the latest STM32L4 package (V1.18.0) so I wanted to roll back to a previous version. STM32CubeIDE won't let me change versions, even if I have multiple versions installed and it insists on only using the newest one. I unins...

I've been having issues with getting an SD card working on an STM32L4R5ZI Nucleo board when using essentially the same code (with minor tweaks) without issues on the STM32WB55 Nucleo board. I've been going through the code of both to determine where...

I am currently trying to get an SD card working with SPI on an STM32L4R5ZI Nucleo board, using STM32CubeIDE V1.13.2 using the latest L4 embedded package. I currently have my code opening the card and even opening the file (I receive FR_OK for both, e...

I know this is probably a really *** question but how do I actually use the data I send from the A4 to the M7 of the STM32MP1 chips? I ran the examples that are clearly setup to send messages from the M4 to the A7 via the virtual UART, which are the...

I wanted to second what @TDK said. I've never had an I2C application work without left shifting the address by a bit (and I almost always forget to do this initially and run into this same issue). Best bet with any comms issue is to hook it up to a...

I didn't even think about that . . . it makes sense, if it's sending a pointer rather than sending an actual data type. I changed byteswritten from a unit16_t to a uint32_t and that seemed to resolve the issue. I assume this is the correct way to r...

I did one better and deleted it altogether. Turns out there's an instance in fatfs.c so I just used that one (apparently, I was creating an unnecessary second instance). It doesn't look like that one is initialized though so I can do that. Is the ...

Ok, found a solution. I ended up making a *.ioc using MXCube, closing it out, and then editing the *.ioc file to change V1.18.0 to V1.17.2. That seems to have fooled it into accepting V1.17.2. I imagine you can probably create one in STM32CubeIDE ...

Found the release notes for L4+ embedded package and found this line in the notes:HAL SPI update Fix driver to don’t update state in case of error. (HAL_SPI_STATE_READY will be set only in case of HAL_TIMEOUT).I'm not entirely sure what problem this ...
