Hello,
I did some hacking. I have the CAR stage booting, I hacked the RS690 code and early SB600 code to work on SB700/RS780. However I'm stuck with ht - reset. I'm not able to set the new HT settings - the documentation disagrees with reality. The docs are bad also for 690.
8.4.2 Changing to High-Speed HyperTransport 1 Mode suggests to write new freq NBCFG x d0 [11:8]. This reg is RO. I tried to do the same as 690 code but the reg seems to be RO too.
So I'm stuck. It would really help if AMD could release the code.
I released the SerialICE patch for this board and I also mapped the GPIO settings.
Thanks, Rudolf
