i.MX6q Sabre SD : boot from SPI NOR

[GabrielHuau]

Hi,

I'm trying to boot from the SPI NOR with the i.MX6 Sabre SD. I'm able to boot from the eMMC and SD slot, but when I flash the NOR with u-boot at 0x400, boot switch 6 and 7 are set to "1" and others to "0", I'm not able to start u-boot. I tried with the i.MX6q Sabre Lite, and no problems (but no switch to configure the boot mode).

Someone succeed to boot from SPI NOR with the Sabre SD ?

Best regards,

Hello Gabriel,

Do you manage to boot from the SPI NOR with i.MX_6DualLite_Sabre-SDP Platform?

If so, can you  explain me how?

Best regards.
