Hello All,
Is it possible be read POST Codes on LPC Bus ? The board will be very similar to AMD/DB800
There is no PCI slot on the board I plan to run coreboot. But it has a LPC header that I can make use off. There is a serial port on the system and this happens to be my main debugging tool, I am looking for a tool that I can rely on if some thing happens before I get to see the serial messages....
If so can you please recommend the LPC POST Card that I can buy. I came across "Artecgroup programmable LPC dongle" but it costs 150 EUR.
Regards, Phani

That will do more than you want but you can use it as the ROM so you don't have to reprogram the flash all the time. Maybe someone else knows of some other options.

Also if the board has an LED connected to a GPIO output you may be able to toggle it for 1 bit of information. Whether programming GPIOs is any easier than getting the serial port working depends on the chipset.
