Hi NXP team,

Currently we have plan of upgrading the OS from Android 6 to 9 with custom board(Sabresd quad Processor, IMX6Q).
During this process we made changes to android 9 with having existing android 6 BSP document and build is also success but flashing is getting hung at th uboot-imx.dtb file .

FYI :

Board Name : customboard
Reference : sabresd quad -imx6
lunch command : 14
Zimage : out/kernel/
uboot-imx.dtb : out/uboot-imx
tool - uuu and mfgtool
android : android_p9.0.0_2.2.0-ga
Source code : android_p9.0.0_2.2.0-ga


Below are the changes we made for custom board from referernce board.

1. PMIC :
SW2 is set to 3.3V
• SW4 is set to 1.975V
• VGEN5 is set to 2.8V
• VGEN6 is set to 3.3V

"regulatorboot-on” is set for sw4

2. DDR3

Is there any tool for flashing the custom board? currently, we are using the existing/customized android 6 uuu tool .

Is there way we can flash binaries to custom board other than uuu tool or mfg tool ?If so please share the details and scripts

Hi Lavanya

 

for programming options one can look at  Android P9.0.0_2.2.0   Documentation

sect.5 Programming Images, sect.7.2.1 Using ADB to update the Android platform

Android™ User's Guide.

 

Best regards
