Hello,
I am using Fash TE28F320-C3
I've read various posts into the mail history in linux-mtd and arm-linux and I've not yet understood if this C3 flash type is
properly supported into the kernel-2.4.19 neither 2.5.x.
I've got this error and I think I need a patch for C3 flash.
If it already exist could I port it to 2.4.19-rmk4 ?
I hope the information below are sufficient to understand the problem,
if not I will be pleased to provide it.
TIA
