Hi, Andy, Balaji:
Right now, I use andy-tracking branch, and the version I built
was 2eb3742db1ecd3d9ffe8f02eaa8def1b2bd2a2c2.
I copied arch/arm/configs/gta02-moredrivers-defconfig to
.config, then I used the build script to build.
After the build, I got uImage-GTA02.bin and
uImage-moredrivers-GTA02_andy-tracking_2eb3742db1ecd3d9.bin. I think
they are the same. That are the image I used.
I changed the runlevel to 3 and tried as I can. The resume
seemed not work for me. and I got a resume panic log by using debug
board, as attached file. Any ideas about what I may do wrong ?
Thanks in advance.
BR.
