You have target mode working?

cfg4icmd will only happen if we support cdbs greater than
16 bytes in length. I have not been able to test this yet,
so the code has not been written. The load_overrun_buf code
has never been exercised either. It is missing a ret on line
2394.

Yes, these were fixed recently. In general, the definitions
for registers that have never been used may not be 100% correct.
I spent several hours one day just typing them in and the process
was error prone. I always validate definitions prior to their
first use in any code.

Should be 0x0CB

If you used a web browser to download it, it may already be uncompressed.
Just use tar without the gunzip option. The "file" command should also
indicate that the file is not compressed.

Not until the next revision of the silicon. Although Rev A can be
made to work as a non-packetized target, there are several bugs that
make this task "unpalatable". Rev B has pretty solid non-pack target
mode, but is still lacking packetized target mode. Rev H1B (single channel
version) should have this all fixed, so I will be targeting it for
target mode applications.
