To use i.MX6 SPI-NOR boot.

Hi community,


I will use SPI-NOR boot for my custom i.MX6Q board.

Then, I want to confirm how to modify MCIMX6Q-SDP board schematic for SPI-NOR boot.

Please my questions below.



According to i.MX 6Dual/6Quad SABRE-SD Linux Release Notes, I understand KEY relative PINs don't support SPI boot.

Then, should I change all SPI-NOR pin assignments  (CLK, MOSI, MISO, CS) from KEY relative pins?

Or can I use if a specified pin is changed from KEY pin?)

(e.g. I can use SPI boot if CS singal is changed from KEY_ROW1 pin to EIM_EB2 pin)



I understand SABRE-AI can boot from SPI-NOR, and it uses EIM_Dxx pins for SPI-NOR.

Then, I want to confirm whether i.MX6 support SPI-NOR boot from pins other than EIM_Dxx.

(e.g. CSI0_DAT pin for SPI clock, DISP0_DAT15 pin for SPI chip select, etc...)

Could you let me know it?



Best Regards,
