Here's my problem. I have two pxa 255 boards , one with ST flash and one with AMD. I configured them to use the lubbock flash driver , and made one partition for jffs2. sorry i dont have the board with me, i shall post the dumps soon.. On both the boards, it boots up properly , performs all file operations smooth ...mount , read write etc.. on the AMD , this performance is consistent even after powering the board down. But on the ST , the moment you power down the board ! , the next time , it only mounts , but doesnt let me perform any fops. I keep getting I/O errors..for only write operations... read works , coz i could ls in the partition. It also doesnt let me format the partition. So I upgraded , the mtd subsys , along with jffs2 , but still the same behaviour... Also , after upgrading mtd , i found that , the lubbock driver uses ioremap_cached and DMA , which is not available in 2.4.19 , so i disabled all of it , but then the cfi probe fails , and only rom_mapping works... due to which im guessing , mtdblock0 gets write protected and mounts jffs2 as read-only. So I used the physmap driver , created one partition just like the lubbock driver .. , but then again , it mounts it as ro !! here again , only ROM mapping works , it doesnt detect the flash type anymore. I have enabled Intel/Sharp , ST and AMD flash driver options in the CFI submenu. Before upgrading the mtd , these options used to work. Can anyone , give me a lead here ?
