Hello all, I am new to andorid and I am trying to port android 4.4.3_r1 to am43xx platform. I used am335x JB release as a reference.
The kernel version that I am using is 3.12.10, and I applied all the android patches that is applied on 3.10 linux kernel to my kernel. And also I am able to add a new device (with reference of am335x directory in am335x JB release) to the device directory for am43xx and build it successfully. The bootargs is given below *bootargs=console=ttyO0,115200n8 androidboot.console=ttyO0 mem=256M root=/dev/mmcblk0p2 rw rootfstype=ext4 rootwait init=/init ip=off* *fdtfile=am437x-gp-evm.dtb* *bootcmd=mmc rescan ; fatload mmc 0 0x80F80000 am437x-gp-evm.dtb; fatload mmc 0 81000000 uImage ; bootm 80F80000 - 81000000* *uenvcmd=boot* And while booting I am getting the following problem. Please help me to solve this. Starting kernel ...
