Hi *, I'm trying to enable MTD and JFFS2 on an Intel 28F160F3 chip but have some problems.
The basic problem is what the physical start address of flash mapping is? While on PPCBoot, I got flash information using command 'flinfo'. The start address is FFE00000. Is this address the one used to configure CFI flash device in physical memeory map? I tried using this address but 'physmap' couldn't find flash device. -----------------clip----------------------------------------- root at ib8sw:~# modprobe -a physmap physmap flash device: 100000 at ffe00000 CFI: Found no Physically mapped flash device at location zero -----------------clip----------------------------------------- -----------------clip----------------------------------------- => flinfo Bank # 1: INTEL 28F160F3 (16 Mbit, top boot sector) Size: 2 MB in 39 Sectors Sector Start Addresses: FFE00000 FFE10000 FFE20000 FFE30000 FFE40000 FFE50000 FFE60000 FFE70000 FFE80000 FFE90000 FFEA0000 FFEB0000 FFEC0000 FFED0000 FFEE0000 FFEF0000 FFF00000 (RO) FFF10000 (RO) FFF20000 (RO) FFF30000 (RO) FFF40000 FFF50000 FFF60000 FFF70000 FFF80000 FFF90000 FFFA0000 FFFB0000 FFFC0000 FFFD0000 FFFE0000 FFFF0000 FFFF2000 FFFF4000 FFFF6000 FFFF8000 FFFFA000 FFFFC000 FFFFE000 => -----------------clip----------------------------------------- I haven't dived into the routine 'do_cfi_probe()' yet since I'm not sure if the start address I specified is correct. Any help is greatly appreciated. - Shawn. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
