Ouch. Do they differ a lot? Can you run xxd on them and then diff? Bit errors indeed start showing when the chip has been through (quite) a few erase/rewrite cycles. I had not heard about that write protection idea before. > > Can you get a few other flash chips for further testing? > > Today I telephone with the Galep producer and he said - some chip > vendors use a "writeprotection technic" that u cant use the free > samples to burn your own image on it.

If you are a company and have a budget for more than just a few chips you can usually get a decent deal for 30 chips (one tube) from the local component distributors. Price goes down a lot when quantity goes up, so I doubt Insyde is paying very much.. :) //Peter -- linuxbios mailing list linuxbios@linuxbios.org http://www.linuxbios.org/mailman/listinfo/linuxbios
