I'm trying to get a ballpark estimate of what sort of current draw consumption I can expect if we migrate to the H7R3, which uses a SMPS for the core, as opposed to the built-in LDO for the core on the H750.Is there a place I can compare the current ...

Hello,I'm having an issue while programming a small section of FLASH memory during runtime of my device.Our device executes its program from FLASH memory. In-addition, we reconfigured the systick timer to run at 20kHz and this is the heartbeat of our...

Hello,For a few months now I have been having issues with writing data to flash memory on the STM32H743ZIT6. Most of the time, everything works great and I am able to read the data from flash successfully, but every now and again, the flash memory ge...

I thought you might say that! Unfortunately our application is big enough where we have to use both bank 1 and 2.I went ahead and updated our bootloader and linker to run from SRAM. It resolved my issue. No more glitch. Thanks for the confirmation. :...

Hi @F.Belaid I just wanted to thank you again for the help with my issue. As of today, we have shipped 100+ units and had zero field failures since checking and clearing the RDS and RDP bits before erase/write operations.

I think you can just add another case called "CTRL_TRIM" and then instruct the BSP to erase whatever blocks are requested. You can call HAL_SD_Erase(&hsd_sdmmc, st, ed) instead of BSP_SD_Erase();The return value of this function when the command CTRL...

This is great advice @Pavel A.. The user interface of the product I am developing for is fairly simple but I've put together a system that now shows some error codes using LEDs when this exception is generated. The user can then clear them and the d...

Hi @F.Belaid this is great information and I am feeling hopeful this may be my issue. I am now clearing the RDS and RDP errors prior to erase and write operations and so far so good. I have created a system to check the flash status register and log...
