Hi Roger and all,
I can start fennec on my board, but all the pages I opened were blank
and cannot display anything, could you give me some suggestions? I suppose
maybe some configuration files are not correct. Thank you.

So you should definitely remove mtune=cortex-a8 for your all building, not just
for this app. Otherwise, you don't know when you would trigger this similar
issue again.

Are you talking about one feature bug? It did not relate with above issue.

Hi All,
Thank you so much for your help and I found the root cause of this
issue on my board, fennec generates an instruction that our processor cannot
deal with which is 'vmov d16, r0, r1'. It uses the higher 16x64 extension
registers which does not have in our processor.
I can run this app now, but all the pages I opened were blank and
cannot display anything, could you give me some suggestions? I suppose maybe
some configuration files are not correct.
B.R
Paul

Hi Imdat,
Thank you for your reply and I will check if this is the root cause.

If the app was running (i.e. you didn't get that when you started), then it can
also mean that your stack was corrupted, resulting in an illegal instruction on
the stack. Check whether you did anything on your stack that might have
negative impact on stack consistency.
