I m using custom board same as MPC8272ADS board. u-boot is u-boot-1.1.2. linux-2.6.10 Flash AM29LV641ML no.of flash chips are 2 I have already tested jffs2 in 2 ways on MPC8272ADS board.......... = =20 1) booted kernel with root as nfs and after that mounted jffs2 using comman= d mount -t jffs2 /dev/mtdblock0 /mnt its working fine. 2) with root as jffs2....it is also working fine. Now i m testing jffs2 on Custom board... case 1 is working fine but 2nd is not working.. I have enabled DEBUG options in kernel so it is reading correctly as cfi datas as per datasheet. here is bootlog for Custom board... bootlog for case 1 ------------------------------------------------ physmap flash device: 1000000 at ff000000 Primary Vendor Command Set: 0002 (AMD/Fujitsu Standard) Primary Algorithm Table at 0040 Alternative Vendor Command Set: 0000 (None) No Alternate Algorithm Table Vcc Minimum: 2.7 V Vcc Maximum: 3.6 V No Vpp line Typical byte/word write timeout: 128 =C2=B5s Maximum byte/word write timeout: 256 =C2=B5s Typical full buffer write timeout: 128 =C2=B5s Maximum full buffer write timeout: 4096 =C2=B5s Typical block erase timeout: 1024 ms Maximum block erase timeout: 16384 ms Chip erase not supported cfip->DevSize=3D0x17 Device size: 0x800000 bytes (8 MiB) Flash Device Interface description: 0x0001 -
