I tried NPL v3 with the current trunk and an rather old MMC (not
SDCard). This worked immediately without any problem. The card had been
newly formatted with FAT (not FAT32) on a Windows PC.

Anyway, I'll use other NPL versions and SD-cards to reproduce the problem.

Note, that there are 2 known bugs with Ethernut 3.0E and memory cards:
