I am trying to use recovery.img for upgrading android images (boot.img, system.img, recovery.img) in eMMC Nand flash. Please suggest if it is feasible to hack recovery.img to automate the upgrade process. Please provide any link or document in this regard.
Problem while using recovery.img
When i boot sabresd board in recovery mode (by pressing vol-down button) from eMMC, the boot up process hangs at "Freeing init memory" and android recovery icon appears on hdmi display. The same image boots up properly in normal mode with the bootargs=console=ttymxc0,115200 androidboot.console=ttymxc0 init=/init vmalloc=400M video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off video=mxcfb2:off fbmem=28M androidboot.hardware=freescale.
Thanks & Regards,
