WebIf the page are 2k+64B you should read 2k+64B when OOB are requested. If the controller only returns 2k+32B, then perform a random read to just move the read pointer to mtd->size + mtd->oobsize - 32 and retrieve the missing 32 bytes? 1) raw read can read out the whole page data 2k+64B, decided by the len in the controller raw read command: Webspecify a size of 0x600000 then mtd_debug write will try to read 0x600000 bytes from the file, and fail like it does above if it cannot find it all. The 'fread(): Success' line indicates that the read actually went well, but bumped into an end-of-file before all data could be read.

WebYour /proc/mtd shows an erase block size of 64 KiB (0x10000). The size of the "image" partition (0x1202c0) is indeed not a multiple of the erase block size. The closest (though slightly smaller) is 0x120000 (1152 KiB); the next largest is 0x130000 (1216 KiB).
