PXA270 BSP

Postby Will137 » Tue Feb 13, 2007 1:24 am

Hi,

I am trying to get the DBPXA270DP BSP running on my PXA270-based device.

I am using a custom bootloader to load the image and so far it is running through the startup code okay, but halts when it goes to start procnto.
I think it could be because of the bootloader I am using, but am unsure why it would make the startup code run successfully without getting to the kernel. I am using QNX 6.3.

My debug output is as follows:

For anyone interested, the startup code, after initialising the MMU, wasn't waiting until the MMU was ready before jumping to the virtual procnto address. This was causing it to hang.
