Hi all,<br>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. <br>now I use BDM to test the RAM ppcboot, I see "=>" from minicom, but printenv command returns:
<br><br>=> printenv<br>bootcmd=bootp; setenv bootargs root=/dev/nfs rw nfsroot=$(serverip):$(rootpath) ip=$(ipaddr):$(serve+>>>rip):$(gatewayip):$(netmask):$(hostname)::off; bootm<br>baudrate=115200<br>loads_echo=1
<br>preboot=echo;echo 'Type "run flash_nfs" to mount root filesystem over NFS';echo<br>clocks_in_mhz=1<br><br>Environment size: 278/16380 bytes<br><br>then I use flinfo command to see flash info :<br>it returns:
<br>Bank # 1: Unknown Vendor flash_info: size=50502, sector_count=4, flash_id=94204020<br>Unknown Chip Type<br> Size: 0 MB in 4 Sectors<br> Sector Start Addresses:<br> 10000000 10182036 (RO) 00102830 (RO) 00010220 (RO)
<br><br>Bank # 2: Unknown Vendor flash_info: size=40062280, sector_count=24576, flash_id=90200<br>Unknown Chip Type<br> Size: 1024 MB in 24576 Sectors<br> Sector Start Addresses:<br> 40002001 (RO) 00001402 00004000 00100100 (RO) 01000210
<br> 00014020 (RO) 10000980 (RO) 08204040 00000521 80408210 (RO)<br>.....<br><br>it seems that variables is not correct, the correct flash_id should be 0x0000 000B according to my modify.<br><br>how dose it happen? and please offer me some suggestion?
<br>thanks<br>
