i.mx8M Plus Falcon mode: spl jump to kernel

[mengfei]

Dear:

I’m implementing Falcon Mode using NXP’s app note AN13709. now i successful achieve spl jump to kernel but have below error messenge. can you read it and tell me how to deal? 

the desg print the below messenge then stop

snvs_pwrkey: probe of 30370000.snvs:snvs-powerkey failed with error -22
i2c /dev entries driver

Can someone tell me where the error occurred？

my best wishes for you

Hi @mengfei ,

I hope you are doing well.

This issue could be due to the Device tree (FDT) not being loaded correctly or an incorrect device tree.

To enable FDT in Falcon mode,

One needs to prepare FDT for SPL using u-boot (non-falcon mode).

Please make sure to follow step 18. in 4.3 Implementation in Linux Boot Time Optimizations for i.MX8M Family

Thanks & Regards,

Hi,
Does Falcon mode support booting from EMMC? In the manual, it is now booting from TF card.

Hi @mengfei ,

I hope you are doing well.

NXP Yocto BSP does not support Falcon mode by default.

AN13709 has Falcon boot mode steps only for SD card.

Does Falcon mode support boot from EMMC? 

=> It should support Falcon boot from eMMC

.

     As Falcon mode does not support uuu. one has to boot normal mode u-boot from an SD card to flash ATF and Falcon bootloader image to emmc.

If the previous error message is resolved, can I mark this case as close?

Thanks & Regards,

Sanket Parekh
