Hi Lukasz,

Hi Sherry,
From: Sherry Sun sherry.sun@nxp.com
The SPL SDP is configured as BOOT_DEVICE_BOARD, so when booting from USB, change its type to BOOT_DEVICE_BOARD, so we can use SDP.

It is spl sdp need it. SPL_LOAD_IMAGE_METHOD("USB SDP", 0, BOOT_DEVICE_BOARD, spl_sdp_load_image);
My point is why this error was not apparent earlier (or when I was using the uuu with newest u-boot)?
The patch changes the i.MX7/8/8M spl_boot_device, i.MX7 already have BOARD support. i.MX8/8M has not been verified SDP before, so this patch is to fix for i.MX8/8M SDP.
Regards, Peng.
I'm just curious why let's say "average" uuu/SDP user did not encountered this problem (as I had also to recover SPL on my i.MX6 board).
Regards, Peng.
I've been using recently SDP (with uuu on imx6q) and I did not experience any issues.
default: return BOOT_DEVICE_NONE; }
Best regards,
Lukasz Majewski
