RiotBoard problem w SD booting

Question

Hi

I have a problem with my RiotBoard. I can not boot from SD card inserted into J7 ( microSD slot). Nothing works, even u-boot does not start

When I take the same card and put it into SD adapter and insert it into J6 ( SD card slot) , board starts ( uboot is alive - I can see output from u-boot, kernel etc .) I checked DIP settings in both cases and are ok ( "Boot Device: SD ")

What is a problem with J7 ? How make it working ?

Are you using the same switch settings for both?

The switch settings for booting micro SD are not the same as SD as follows:

Micro SD J7

D1 D2 D3 D4 D5 D6 D7 D8

1 0 1 0 0 1 1 0

SD J6

D1 D2 D3 D4 D5 D6 D7 D8

1 0 1 0 0 1 0 1
