HAL MMC card initialization always fails #45

Closed nickstoughton closed 2 years ago

nickstoughton commented 3 years ago

Setup

Nucleo-F746ZG board, but present for at least all F7xx processors (and probably many others)
Found using gcc 10.1

Problem Any attempt to call MMC_InitCard() will fail

How To Reproduce 1.Attach an eMMC card (1-bit, 4-bit or 8-bit data paths, it will not make a difference) to aSDMMC port (NOTE, eMMC cards use the JEDEC MMC protocol, and not the SD Card protocol).

2.Attempt to initialize it. This call will fail under all circumstances.

Patch Please see attached patch patch.tar.gz

Hi @nickstoughton,

This issue has been fixed in the frame of version v1.16.2 of the STM32CubeF7 published some time ago. Please allow me then to close it.

With regards,
