I have panda board Rev A6. I tried to port JB 4.2.1 on it. But it could not boot up. If I tried the same thing with my older panda board Rev A4 it works fine. After some googling I come to know that both have different memory. I had made changes accordingly in the kernel and boot loader. After those changes Kernel boot starts but when it tries to up Android FS it stuck. Nothing comes with serial console.
Any solution please.
