Hi NXP team:
I need OTA function in imx6q-sabresd.
When I input the command as below:
sabresd_6dq:/ #
sabresd_6dq:/ #
sabresd_6dq:/ #
sabresd_6dq:/ # reboot recovery
But it can not enter recovery mode,it boot up normally .
Could anyone tell me how to change it ?
Hi, yingjin yan
Which Android BSP version are you using Android 7.1.1/7.1.2?
As Reboot recovery command is not supported in Android 7.1.1 u-boot. You have to add support for reboot recovery command in Android 7.1.1 AOSP. You can use Android 7.1.2 instead.
For Android 7.1.1, you can enter in recovery mode manually by pressing "VOLUME DOWN" and "Power SWITCH" after the system completes the bootup.

Shivani

Could you give some advice for porting recovery function to Android 7.1.1
Should I only porting uboot ? or uboot and kernel ?
Hi,
About recovery mode you can refer to the steps in the document Android_Frequently_Asked_Questions:
33 How do I update my device with the OTA Package?
Updating by Android fastboot
