Hi,
I am trying to update latest upstream kernel on mphackbox TC2 board
according to this wiki.
https://wiki.linaro.org/Platform/LAVA/DevOps/TC2TilesOnLavaServer/hackbox
I use vexpress-v2p-ca15_a7.dts and vexpress_defconfig kernel config.
after make kernel and dtb images, I updated them as u-zimage.bin and
u-dtb.bin. but the kernel keep panic:
Did I miss sth or the just kernel broken?
