uboot for NAND flash

jimmychiang — Sun, 11 Jul 2021 01:46:28 GMT

Dear Sir!

I have a MCIMX7SABRE EVB.

I tried build U-Boot and Kernel in standalone environment.

And I refer to the imx-yocto-L5.4.70_2.3.0 doc, and the compilation environment has been established.

However, because I need to boot from NAND flash. So I tried to compile with the following instructions.

=============================================================

Download source by cloning with git clone https://source.codeaurora.org/external/imx/linux-imx -b
imx_5.4.70_2.3.0
cd linux-imx
make imx_v7_defconfig
make

=============================================================

But the "imx_v7_defconfig" file has no NAND Flash configuration.

In fact, I have used "mfgtools\Profiles\Linux\OS Firmware\firmware\u-boot-imx7dsabresd_nand.imx" and program to NAND flash, it is working on MCIMX7SABRE-EVB.

So I think there should be a configuration file for "u-boot-imx7dsabresd_nand.imx".

However, there are many configuration files in uboot source code. (in "uboot-imx\configs" path)

Could you help me and let me know which configuration can be used for NAND boot on MCIMX7SABRE-EVB?

Thanks!

for uboot configuration one can look at sect.5.5 U-Boot configuration i.MX Yocto Project User’s Guide
