Re: [flashrom] [coreboot] flashrom on MCP73
Hi Fabrício, [Followup to flashrom@flashrom.org please] some of us are interested in reverse engineering flashrom SPI support for your chipset. Do you still have that board available? On 15.01.2009 18:12, Fabrício Ceolin wrote:

Chipset MCP73 / SPI chip Macronix MX25L8005.
We made modifications using a enable_flash_mcp55 function, but does't work.
First you have to figure out what chip is the SPI bus master.
We made these tests. There are a superio, but the bios chip isn't connect to it. The bios chip is directly connected to the chipset MCP73.
So, I need to the datasheet of MCP73 to implement it.
Did you get any datasheets from Nvidia? Regards, Carl-Daniel -- Developer quote of the week: "We are juggling too many chainsaws and flaming arrows and tigers."
Hi Fabrício, latest flashrom now has some debug output which should be helpful in providing SPI support for your MCP73 board. Could you run "flashrom -V" with flashrom revision 902 (or later) and send the output to flashrom@flashrom.org? Thanks. Regards, Carl-Daniel On 08.10.2009 15:23, Carl-Daniel Hailfinger wrote:
