I have a setup with u-boot-1.1.6 with the nand/jffs2 subsystem enabled and I have a flash that has been formatted with 'flash_eraseall -j /dev/mtd0' in Linux. Additionally a PPC uImage for this 8241 target has been put on the flash. At this point, I reboot, set the mtdids and mtdparts and try an fsload and here is the result.

I8000E> setenv mtdids nand0=atx-0 I8000E> setenv mtdparts mtdparts=atx-0:16M@0M(rootfs1) I8000E> fsload ### JFFS2 loading 'uImage' to 0x100000 Scanning JFFS2 FS: - ... read_nand_cached: error reading nand off 0xdfe200 size 8192 bytes read_nand_cached: error reading nand off 0xdfe000 size 8192 bytes read_nand_cached: error reading nand off 0xdffe00 size 8192 bytes off = 0xdffff8 magic 0x0 type 0x0 node.totlen = 0 . done. ### JFFS2 load complete: 936990 bytes loaded to 0x100000 I8000E> md 0x100000 00100000: 27051956 6ed7fc8a 4587f48c 000e4bde '..Vn...E.....K. 00100010: 00000000 00000000 dd803a34 05070201 ..........:4.... 00100020: 4c696e75 782d322e 362e3137 2e313100 Linux-2.6.17.11. ...

So, this leads to a few questions: 1. Why might there be occaisional read_nand_cached errors? 2. Why does the load take 5 minutes? 3. Why does the load appear to complete successfully, the bootm start, but then there is a GUNZIP error and the board reset?
