Hi all,
now the SDRAM and Flash size of my board is increased, so the ppcboot needs
to change, I changed the board/TQM8xx/flash.c  and tqm8xx.c, and some other
files.
now I use BDM to test the RAM ppcboot, I see "=>" from minicom,  but
printenv command returns:

=> printenv
bootcmd=bootp; setenv bootargs root=/dev/nfs rw
nfsroot=$(serverip):$(rootpath)
ip=$(ipaddr):$(serve+>>>rip):$(gatewayip):$(netmask):$(hostname)::off; bootm
baudrate=115200
loads_echo=1
preboot=echo;echo 'Type "run flash_nfs" to mount root filesystem over
NFS';echo
clocks_in_mhz=1

Environment size: 278/16380 bytes

then I use flinfo command to see flash info :
it returns:
Bank # 1: Unknown Vendor flash_info: size=50502, sector_count=4,
flash_id=94204020
Unknown Chip Type
  Size: 0 MB in 4 Sectors
  Sector Start Addresses:
    10000000      10182036 (RO) 00102830 (RO) 00010220 (RO)

Bank # 2: Unknown Vendor flash_info: size=40062280, sector_count=24576,
flash_id=90200
Unknown Chip Type
  Size: 1024 MB in 24576 Sectors
  Sector Start Addresses:
    40002001 (RO) 00001402      00004000      00100100 (RO) 01000210
    00014020 (RO) 10000980 (RO) 08204040      00000521      80408210 (RO)
.....

it seems that variables is not correct, the correct flash_id should be
0x0000 000B according to my modify.

how dose it happen? and please offer me some suggestion?
thanks
