Hi All,
My Juno board could run a big-endian kernel, but it just work in UP mode, when I compiled
the kernel in SMP mode, it always halted in "arch_spin_lock".
I checked the PE status, when halted, pc register alway point to line 3 which is the code of
"arch_spin_lock".
line1 " sevl\n"
line2 "2: wfe\n"
line3 " ldaxrh %w2, %4\n" //pc always point here
I don't know how this could happen, and really need some help to make Juno board run a SMP
kernel.
Thanks
Best regards
It works fine with the mailine kernel on my Juno setup.
Just post the issue(if you still have) on the ALKML with details of your kernel version(preferably latest mainline)

Hi Sudeep,
The code I used is get from linaro, and I think that code couldn't intend to support big-endian kernel.
I update that code with some patches for big-endian, and the kernel could run stably.
