The board revision is E 03/2003
It has the following chips:
About 1cm square
NxtWave communications
Nxt 6000
DD8376
1A1 0304
Ok, then they still have the Ntx6000 onboard. Hmmm - I read again your
first mail and there you mentioned that it was already working, so sorry
for confusion. But now I remember the problem: Gerd Knorr said that the
bt8xx it is not able to send zero-byte messages using the hardware i2c
controller thus you get -EINVAL when trying to check which PLL is
onboard - so you need the software bitbanging driver for the nxt6000.
