I've now successfully booted a 3.0.38 kernel. Couldn't get SD booting to work,
so the only way to do that was to put a kernel with hardcoded
"root=/dev/mmcblk0p2" as bImage into nanda.

The kernel is booted directly, not via u-boot (as mentioned on
http://elinux.org/Hack_A10_devices ), in linux/linux.ini

    [segment]
    img_name = c:\linux\bImage
    img_size = 0x2000000
    img_base = 0x40008000

I suppose this leads to a lack of certain initializations that the kernel
came to expect from u-boot. So I am attaching the dmesg. Some highlights:

[    0.000000] Total Detected Memory: 16MB with 1 banks
[    0.000000] 64 MB reserved for MALI

[    0.000000] Memory: 640MB 16776528MB = 16777168MB total
[    0.000000] Memory: 511960k/511960k available, 143404k reserved, 0K highmem

This one is supposed to be a 1GB unit, but not even the stock android sees
1GB, so I wonder if this is just a fraud by the supplier (TomTop).

I am attaching dmesg from Android as well, just in case.

With respect,
