I am trying to do android recovery mode in Sabresd board. In my environment, I use HDMI as output display, no LVDS.
Below is my U-boot bootargs:
console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 vmalloc=400M androidboot.console=ttymxc0 no_console_suspend androidboot.hardware=freescale
To enter recovery mode, I do folllowing steps:
1. copy sabresd_6dq-ota-.... .zip to /cache
2. create a file "command" in /cache/recovery, the contents of this file represent the filename of update package, it should look like below:
3. in CLI, execute "reboot recovery"
4. system reboot and get into recovery mode
In previous android release (imx-android-13.4.1), I can see rolling star in Android icon on HDMI display which represents the update process is running.
But In JB 4.2.2 ga release, No HDMI display, but I can confirms the recovery is running.
I had try to add "--show_text" in command file and it can display static pic, but cannot see like previous "rollong star" in Android icon.
Anyone can figure out what I miss?
Thanks in advanced.
