how to customize UI menu for android recovery mode

chenguoyin — Tue, 19 Aug 2014 06:35:42 GMT

Since JB4.3, we have added a customer library in myandroid/devices/fsl/common/recovery to give a chance for customer to customize their UI menu in recovery.img

By default, we define below menu as below:

const char* ITEMS[] = { "reboot system now",

"apply update from ADB",

"wipe data/factory reset",

"wipe cache partition",

NULL };

Below is an example to add a new menu as "apply update from SD Card":

diff --git a/common/recovery/recovery_ui.cpp b/common/recovery/recovery_ui.cpp

index ccf8ccd..9cbd91e 100644

--- a/common/recovery/recovery_ui.cpp

The handle on the menu is defined in function prompt_and_wait(Device* device, int status) in myandroid/bootable/recovery/recovery.cpp. Below is the buildin menu function in recovery.

enum BuiltinAction { NO_ACTION, REBOOT, APPLY_EXT, APPLY_CACHE,

APPLY_ADB_SIDELOAD, WIPE_DATA, WIPE_CACHE };

Dear Guoyin,

I modified the below file based on your comments, and then confirmed the displayed SD-Card menu in UI menu.

common/recovery/recovery_ui.cpp

But I couldn't update the Android Image because the board couldn't mount sd-card in /mnt/extsd and /sdcard.

and I could confirm the sd-card mounting point in the below files.

1) myandroid/out/target/product/sabresd_6dq/recovery/root/fstab.freescale

/devices/platform/sdhci-esdhc-imx.2/mmc_host/mmc1 /mnt/extsd vfat defaults voldmanaged=sdcard:auto

2) myandroid/bootable/recovery/recovery.cpp

static const char *SDCARD_ROOT = "/sdcard";

Could you tell me how to update the Android image on the board with SD-Card for detailed?

I confirmed the below items for Android Recovery mode & Android Norml mode via SD-Card.

- check the sd-card interface operation in Android normal mode (No Recovery mode)

. SD-Card was mounted as /mnt/extsd when the sd-card was inserted.

. linked the /mnt/extsd to /sdcard, and then we can control the data in /mnt/extsd and /sdcard (after remounting "/" as rw)

- check SD-Card UI menu in Android Recovery mode

. displayed sd-card UI menu after applying your upper comments.

Best Regards,

Eric.

Dear Guoyin,

I found some point to solve the problem.

I compared the init.rc for Normal mode and Recovery mode for /mnt/extsd and /extsd.

init.rc in Normal mode : device/fsl/imx6/etc/init.rc

init.rc in Recovery mode : bootable/recovery/etc/init.rc

In the recovery mode, there wasn't /mnt/extsd and /extsd.

So I think we have to add /mnt/extsd and /extsd into the recovery mode init.rc

mkdir /mnt/extsd 0000 system system

symlink /mnt/extsd /extsd

Is that right?

I'll try to this method.

Best Regards,

Eric.

You also need to update recovery to make sure the /extsd been mounted. By default the extsd volume is not been mounted.

Dear Guoyin Chen,

Thanks for your response.

The SD-Card was not mounted when I applied your guide like as below

1st : ensure_path_mounted("/extsd");

2nd : ensure_path_mounted("/mnt/extsd");

I could see the below log when the board was entered the Recovery mode.

I'm using the JB4.3, and the board have SD-Card(via SD3 port) and eMMC(via SD4).

Could you tell me what's the problem?

Best Regards,

Eric.

We updated the Recovery Image by using fatload command, and others.

Hi,

You have to add the appropriate directory path in recovery init.rc also. Hope this may help others.

Hi,erickang

Have you solved this problem? also my SDcard can not mounted in the recovery mode.If you have done it,could you give me some help?thanks!

Re: how to customize UI menu for android recovery mode

sriramperiyasam — Wed, 07 Oct 2015 06:54:29 GMT

Hi,

you have to add the file system mount entry for the SD card in the file bootable\recovery\etc\fstab.freescale.recovery. And also create the directories needed to mount the sdcard in the bootable\recovery\etc\init.rc file.

Regards

Sriram.

Hi,Sriram

Thank you for your reply.

I have done the two things. 1、fstab.freescale 2、init.rc

But I have the "E:failed to mount /mnt/extsd (No such file or directory)" ,Could you give me some details about it.

Can you share me your init.rc and fstab.freescale?

Thanks

Hi,Sriram

Thank you for your reply. My android version is JB4.3.1.

Below is my fstab.freescale file in recovery mode

2、init.rc in recovery mode

service adbd /sbin/adbd recovery

disabled

# Restart adbd so it can run as root

on property:service.adb.root=1

write /sys/class/android_usb/android0/enable 0

restart adbd

write /sys/class/android_usb/android0/enable 1

There are the vold and mount in In JB4.3,but I don't know how to deal with them.

Thanks

Hi,

Please replace following line

/devices/platform/sdhci-esdhc-imx.2/mmc_host/mmc1 /mnt/extsd vfat defaults voldmanaged=sdcard:auto

with

/dev/block/mmcblk1p1 /mnt/extsd vfat defaults voldmanaged=sdcard:auto

And ensure that recovery image changes flashed successfully since if you flash it using fastboot, it will not flash properly. Try to use manufacturing tool for flashing.

Thanks and Regards

Sriram.

Hi,Sriram

Thank you very much!

I have solved this problem. I used the mount("/dev/block/mmcblk1p1....") command .

I am very grateful to you for giving me so much help。
