Fastest/best way to recover from a SDMMC TXUNDERR error, and write again successfully?

Hello, we are using the SD Card HAL code on an STM32F7. We are pretty much using the default initializers for the peripheral, which leave us atSDMMC2.POWER = 0x00000003 SDMMC2.CLKCR = 0x00000900 SDMMC2.DCTRL = 0x00000033We have some operations that ...

hi guys, I've been trying to write to internal flash for the last two weeks, and unfortunately, I didn't manage to do so. I worked with the function I have from the library and read in the manual.
