[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

So you have at least these two partitions, right?

How many partitions did you configure here, and which sizes  do  they
have?

How big is your U-Boot image?

Are you sure? Is this really 131071 bytes? That would mean  that  the
last byte of flash does not get written to - it should be exactly 128
kB  (also, this sounds too small to me; with a decent set of features
U-boot will not fit in this image). Check your u-boot.map file and/or
the output of objdump -h to make sure you don;t have any  overlapping
sections defined in your linker script.

And please keep the list Cc:ed.

Gotcha!!!

Indeed. As I mentioned before: 128 kB seems too small to me.

Reduce TEXT_BASE in your config.mk file.

Add  a  "Cc:   <U-Boot-Users@lists.sourceforge.net>"   header   line,
probably  by  using  "reply  to  all" or whatever your MUA names this
function.

[Tyler Jia]

thanks!!!  thanks!!!

as your said,
 
After add 128k to size of u-boot.bin, the u-boot with
JFFS2 configure comes up serial port.
I could run setenv and saveenv command.

in ../board/ppc405epvv/config.mk, 
changed from TEXT_BASE = 0xFFFE0000 to 0xFFFC0000  
add 128k.

also:
in ../include/configs/PPC405EPVV.h changed from:
#define CFG_MONITOR_BASE        0xFFFE0000      /*
last 128 kB */  
to 0xFFFC0000, /*last 256K */.

changed from
#define CFG_MONITOR_LEN         (128 * 1024) 
to 256*1024
