Hi,

Booting top of tree U-Boot from the SD card on a sama5d27_wlsom1_ek
board works when  AT91 Bootstrap is used.

Now, I want to replace AT91 Bootstrap with U-Boot SPL.

I copied spl/boot.bin to the VFAT partition of the SD card, and I only
got this storm of the following messages:

Could not initialize timer (err -96)

Could not initialize timer (err -96)

Could not initialize timer (err -96)

Could not initialize timer (err -96)

Could not initialize timer (err -96)

Would you happen to have any suggestions on how to fix this error and
boot sama5d27 using U-Boot SPL?

Thanks,

Fabio Estevam
