Hi,
My M4A785T-M is currently not available for developing, due to a very long fsck(it musn't reboot,restarting from scratch won't speed it up more).
In the meantime I realized that my HP/Compaq nc6320 was very close to the Roda rk886ex, only the superio was different: the Roda rk886ex seem to have 2 superios and one of them is the SMSC LPC47N227, the superio of the nc6320 is the SMSC LPC47N217. The ec is also different...
So I tried to get serial output on the nc6320, hopeing that the ec wouldn't interfer at such early startup, but it seem that or I did something wrong, or the ec is interfering. My last try to make serial work is attached (patch 0001).
Then after that I tried to find a way to have a feedback, resetting the PCI in a while loop didn't make any led blink. However someone named phcoder on the #coreboot IRC channel gave me some example code for grub that should light the keyboards leds(like caps lock for instance),it's available in patch 0002, but that failed to light any led...
The informations gathered on the device are here: https://www.coreboot.org/HP_COMPAQ_NC6320
About the ec: There is an ec rom inside the BIOS(which can be unpacked with the following python uttility: http://paste.flashrom.org/view.php?id=1523
Since the ec doesn't seem to have access to the flash, I wonder how to send such rom to the ec? maybe putting it in RAM at a fixed location is enough? Since I don't have SerialIce working either I cannot look at how the BIOS does it.
Does anyone have an idea on how to proceed at that point? Is my serial Init code wrong? Or can the EC prevent serial output?
Denis.
