[U-Boot-Users] the ppc405ep u-boot (with jffs2 configure) failed

[Tyler Jia]

Hello,


   I am a new user, try to get the u-boot(with jffs2)
work on a ppc405ep board(32M Ram, 8M flash disk, one
serial port, one network port), it will has one
partition for u-boot(128k), the rest make one jffs2
partition, the kernel and initrd will locate in this
JFFS2 partition.
 
   First I build the u-boot.bin without configure
jffs2 support, installed it to 405ep board flash
memory, it works well, when turn on power, from serial
port, I could get the prompt => and excute the u-boot
command like setenv, saveenv. 

  But after I configure u-boot JFFS2 support in
include/configs/PPC405EPVV.h, add 4 lines:

#define CONFIG_COMMANDS		( CFG_CMD_JFFS2 )

#define CFG_JFFS2_FIRST_BANK    0    
#define CFG_JFFS2_FIRST_SECTOR  0
#define CFG_JFFS2_NUM_BANKS     1

(the 8M flash memery havs one bank, 64 sector.)

after make compile, I load this jffs2 configured 
 u-boot.bin to flash memory, turn on power, but
nothing happened on serial port, no display, no prompt
=>, could not type command, it seems u-boot crashed.

 I could not figure out how to fix the problem that
adding jffs2 support crashed the u-boot.


thanks


Tyler
