[U-Boot-Users] fsload questions

[Charles Krinke]

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 at 0M(rootfs1)
I8000E> fsload

## Booting image at 00100000 ...
   Image Name:   Linux-2.6.17.11
   Image Type:   PowerPC Linux Kernel Image (gzip compressed)
   Data Size:    936926 Bytes = 915 kB
   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... Error: inflate() returned -3
GUNZIP ERROR - must RESET board to recover

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?
