hi experts

i want to boot from spi nor flash, on imx7d sabre board,

so using MikroBus i attached a spi-nor flash, i modified u-boot ( 2022.04 version) to support that flash, and i successfully read, update a spi-nor in u-boot,

from a user guide , i know imx7d can boot by spi, but i know not what part to change to boot from a spi flash in u-boot

basically u-boot has SD-boot and qpsi configuration, i tried to use these configuration with fail

any information will be of great help ,

thank you sincerely

Hi,

Thank you for your interest in NXP Semiconductor products,

Your boot device is not supported on 7D-SDB, the boot device you are trying to use is:

6.6.5.4 Serial ROM through SPI. i.MX 7Dual Applications Processor Reference Manual, Rev. 1, 01/2018.

There should be another board with the BOOT_CFG available for Serial SPI and make sure that the boot image complies with Figure 6-38. CSPI flow chart.
