RE: Data abort during kernelInit

Hi Geoff.

It seems that you were right. I try to disable the abort trap on the JTAG
debugger. I checked the address after the data abort and it is now
accessible. So the handler seems to have mapped the page correctly.

Hi everybody.

I'm still working on a BSP for an ARM platform.
I have a question about the kernelInit phase.

During it, a data abort is generated after the VFP detection.
If I disable the data abort exception on my JTAG debugger, the kernel
continues to boot until the launch of shell.exe (it crashes here).

But if I enable the data abort, the kernel stop after the first update of
the eptr thing.
I wanted to know if it's normal to have a data abort here ?

Here the paste of my debug serial output.

Thanks in advance !
