I have noticed lately that when switching between my release and debug build configurations that the code behaves differently. Looking at the Project Build Settings the only difference I see between the two is the Release GCC and G++ compilers are op...

Has anyone had luck with the esp-serial-flash library using an STM32 as a host?I tried to integrate this project into a Cube Project and was receiving ESP_LOADER_ERROR_TIMEOUT upon trying to connect_to_target(). I am basing this off of the STM32 exam...

Has anyone else had problems with the SDMMC peripheral on the H7 since the CubeIDE 1.8.0 Update. I have some old projects I went back to that had previously used this peripheral and now when mounting the SD Card I get a FR_NO_FILESYSTEM error. I have...

We are creating a driver for a W25Q128JV Winbond Nor Flash chip. We are working with a STM32 H743ZI2 board and communicating on the QSPI peripheral with the help of the HAL libraries. Currently the driver can successfully Write to the chip using stan...

Ended up being a signal integrity issue. Changing Pull-Ups from internal in CubeMX to external Pull-Ups on my circuit fixed the issue.The SD Card was working for about 20-30 program cycles and then went back to the state of always returning FR_NO_FIL...

Looking at the logic analyzer from test on the old project this is the expected communication protocolCurrently I am now seeing this communicationIt seemed odd to me to see so much movement on the card detect line.There are currently internal pullups...

To clarify I preform 1 write and then try to read it in single data mode using fast read which correctly reads back all the data confirming that the data on the chip was written. I then try the Quad-I/O or the Quad Fast Read, both of which only get 1...

Here is what I am seeing in the hqspi registers. I have set Sample Shifting to the default (None) but have tried using the shift by half cycle and have not noticed any difference in performance.

At this point none. This project is still in breadboarding stages so we are expecting slower times due to signal integrity but is it expected that the dual read would be working at half the speed of the single read? Or is there some setup that is bei...
