I am absolute beginner but I need to read and write the above mentioned serial Flash memory.
This is a BIOS chip and had a bad flash. Now it is unsoldered from mainboard. I want read it out and reflash a new BIOS file.
Therefore I really need help how to connect the chip pins with the buspirate pins in a correct way.
we have fixed the flashrom website and i have added a table explaining the connections. please see http://flashrom.org/Bus_Pirate#Connections
at first thanks for your help and for giving some more information on the website.
To answer your questions, I am using the Bus Pirate probe kit to connect the buspirate to chip. But I need to solder it at the chip because the test clips are too big for this chip size. It is a 8-SOP (200mil) form factor.
I want to try your solution but there is just one point which is not really clear. Could you please tell me the names of PIN 3, 7 and 8 in your description.
In my case it would mean: PIN 3: 5V PIN 7: CLK PIN 8: MOSI
But CLK + MOSI to WP# and 5V + CLK to VCC makes not really sense to me. I guess your Pins are different to mine.
Please let me know and I will try it.
Thanks and regards, Daniel
