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?

Well the root error is the mmc card initialization. All the rest are the consequences (no directories to mount and process 1 exits leading to the panic). Unfortunately I can't help more.

Thanks a lot for the help!
I updated to latest upstream kernel, it has regulator update. and remove the mmc driver in kernel config, since wiki said it is using USB stick.
but seems this tc2 board is very unstable. sometime it need multi time 'reboot' command. sometime it hang on 'Cmd> reboot',

Anyone can check the hardware unstable issue for this board?

Yeah, that happens on my board too. After the board has rebooted you have to wait a bit (several seconds) before sending a command.

For me it happened only when I choose the wrong kernel or copied the kernel in the wrong place.

Thank you, Daniel!
when I use the latest upstream kernel. the error still exists.
but on 3.12 kernel. I can see the kernel panic on MMC. Without MMC driver on 3.12 kernel. I saw above 'unhandled Exception' again.
Recent kernel is unfriendly to the TC2 board. I give up to play TC2 now.

This could be an issue with kernel image, please ensure you copied zImage ( not uImage) and ensure you have right DTB.
