[U-Boot] U-Boot 2016.03 on Altera Cyclone 5 SOCKIT

[Nathan Barrett]

Hey Anatolij,

Thanks for getting back to me.

I actually just solved this a few minutes ago.  Here's the relevant patch:

I think you do not have CONFIG_SPL_FAT_SUPPORT or CONFIG_SPL_EXT_SUPPORT defined in the board config file and SPL uses MMCSD_MODE_RAW and just reads at offset CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR of the card and not from the partition 3.

SPL reads at byte offset 0x140000 of the device it seems.

Does SPL detect the image if you write it to the sd-card as below?

  dd if=u-boot-with-spl.sfp of=/dev/sdb bs=1M seek=1

But please only write it this way if there is no partition with important data at the beginning of your sd-card.

HTH,

Anatolij
