An update:
I compared the dmesg for debian distro and the working Angstrom distro, I
found that the reading the CSSP revision showed a different value, ie:
val = readw(cam->reg_base_virt + REG_MODE);
produced (in debian):
cam->rev = val & 0xff;
cam->rev = 0x20;
whereas (in Angstrom):
cam->rev = 0x05;
I don't get why the iomem read from CSSP showed different value ?
