Hi,
I’ve been trying to get a QNX image going on a Gumstix XM400 board which has a u-boot bootloader installed. The board runs at 400MHz, has 16mb Flash and 64mb Ram.
I’ve so far been using hte DBPXA250 binary bsp. has anyone successfully booted qnx on a pxa255 using this bsp?
The problem comes when i try to boot the image (directly from RAM in this case) and the board reboots straight away. I get the same effect if i use ‘go a2000000’ or bootm on an image created with u-boots mkimage.
My guess is that the memory mappings and processor speeds are not the same as the DBPXA250 dev kit, however i could not find any specs to confirm this. Is this likely to be the problem or should i be looking elsewhere? If this is the case, will i need the source bsp to configure the image properly or can i hack the binary bsp?
The other thing i thought it might be was the file system type. U-boot expects a jffs2 image, however i dont believe this is the same as what the qnx system builder creates. whats the difference between jffs2 and the ffs3 that mkefs creates?
Cheers,
Duncan
