Why is SPL not used in the mainline i.MX6ULL/ULZ port? The i.MX6UL
(14x14) does use SPL.
Yes, I think it could SPL as well. Maybe Peng can comment.
NXP vendor tree not support SPL, so when I upstream the code, SPL was not
included.
I see. Thanks for the update here. I might work on SPL support, if this
seems necessary for my custom i.MX6ULZ board.
I do have another question though. I'm currently testing QSPI booting
on the i.MX6ULL EVK. And this does not work 100% reliably. Sometimes
the board boots after programming of the IMX image to 0x1000 in QSPI
NOR to the U-Boot prompt. And sometimes I see no output at all. I
do have the QSPI binary programmed at 0x400. BTW, these binaries boot
all just fine when booted via the "imx_usb" loader. Only when booted
directly from QSPI (DIP switches) it fails sometimes.
Is this a known problem?
Do you have a reference U-Boot binary for QSPI booting for the i.MX6ULL
EVK? Best would be including the QSPI header (offset 0x400).
Thanks,
Stefan
