Hi all,
I use BuildRoot and Linux 2.6.19.2 (Denx kernel) on a MicroSys CR825/ PM827 board, but Linux didn't recognize my 32M flash (4 Intel
28F640C3). I have also tried the pm82x_defconfig profile but Linux crash after line "NFTL driver: nftlcore.c $Revision: 1.98 $, nftlmount.c $Revision: 1.41 $".Any ideas ?
Best regards, Guillaume
