I had IMX8Mini EVK, which has MIPI panel., and I am using Android9
By default, the Android build image is HDMI, that's why every time I flash the EVK, I had to use -d mipi:
./uuu_imx_android_flash.sh -f imx8mm -a -e -d mipi
to let my MIPI screen up.
Unfortunately, when I create the OTA package(make otapackage), it seems it still use HDMI by default, so when I OTA the EVK, the screen didn't UP.
Could someone help me to let me know HOWTO create a MIPI-default OTA package instead of HDIM?
Thanks a lot.
Hi, Yang Songxiang
You need to specify the mipi dtbo image to the "BOARD_PREBUILT_DTBOIMAGE" variable for MIPI panel display in OTA package.
e.g BOARD_PREBUILT_DTBOIMAGE := out/target/product/evk_8mm/dtbo-imx8mm-mipi-panel.img
This variable is defined in the BoardConfig.mk file which resides in Android Source at "${MY_ANDROID}/device/fsl/imx8m/evk_8mm/BoardConfig.mk".
After this, you can generate the OTA package for evk_8mm with MIPI panel display.
Hope this will help you.
Let us know in case of any concern.
