Hello
I have been working on AML8726 device that runs LINUX OS and runs KODI. This device is used to watch media over TV set using HDMI cable.
So I had to change this device firmware, but the device OS was locked. I was trying to run a kernel build with buildroot from SDCARD to mount the original OS file system. I had trouble to get working NAND drivers to find and read the existing partitions. When I managed to find and modify drivers that will work, on the kernel boot it has change the Partitioning of the device and the u boot get stuck.
Now it reaches up to here. After it was like this and as you see the partitions are different.
My question is: Are there ways to start uboot from sdcard? or to fix this problem some how, to be able to boot linux kernel or even write commands for uboot. Because right now neither kernel boots , not from nand or sdcard. And it does not run aml_autoscript or anything from sdcard.
