i.MX6UL u-boot-imx v2024.04 CONFIG_BOOT_RETRY_TIME does not work

[securemetersczhang]

Hi,

I am working on migrating u-boot-imx to the latest version v2024.04 GA 2.0.0 under Yocto for our custom board which is based on i.MX6UL.

The u-boot code is based on mx6ul_14x14_evk with nand support since we have a raw NAND.

I the defconfig which I begin with:

The u-boot builds and boots fine.

However, if I add these two configs, it does not work as expected:

CONFIG_RESET_TO_RETRY=y

CONFIG_BOOT_RETRY_TIME=30

The board does not reset itself after I stop autoboot and stay there with no action for more than 30 seconds.

Please help me on this issue. Thanks!

Best regards,

I also tried adding "bootretry=30" to default environment variable. But it does not help either.

Hello @securemetersczhang 

I hope you are doing well.

Could you please point to me what is the U-Boot version that you had before the update?

Best regards,

Salas.

Hi Salas,

Thank you for your reply.

We had u-boot-imx v2015.04. I believe the closet branch is nxp/imx_3.14.38_6ul_engr
