Hi Anton,

At runtime do you get into the code inside npcmx50_sdhci.c, but it
doesn't work well or not access at all?
Can you check those registers (BootBlock should set them for you):
sd1irv1 at address 0xf0800054 value =3D 0xf5c80f80
sd1irv2 at address 0xf0800058 value =3D 0x52001132
sd2irv1 at address 0xf08000b4 value =3D 0xfdc80f80
sd2irv2 at address 0xf08000b8 value =3D 0x52003132

Also try to use attached file.

Thanks,
Avi
