avb_ab_flow.c:30: ERROR: Magic is incorrect.

[wanpengfu]

I use the command "sudo ./uuu_imx_android_flash.sh -f imx8mm -a -e" to update my imx8m mini EVK with the image "android_p9.0.0_2.0.0-ga_image_8mmevk".

The debug UART print the error messge

"avb_ab_flow.c:30: ERROR: Magic is incorrect.
avb_ab_flow.c:112: ERROR: Error validating A/B metadata from disk. Resetting and writing new A/B metadata to disk. "

Can anyone give me an answer? 

Thanks.

你好，

请问你这个问题最后解决了吗？我现在也遇到了同样的问题，求解决方法。

Hello,

This error seems to be related that you are flashing only one of the slots (-a), so when it expects to find the other slot metadata the error pops.

Having both slots are used for OTA updates for android, you can check more of this here

If you need to have both slots flashed you can use the following command

sudo ./uuu_imx_android_flash.sh -f imx8mm -e

Hope this helps,

Best regards,
Aldo.
