Hello
I have a board, pxa based, and it has u-boot burnt, but i don't have the source from which it was compiled from, so i don't have any config setting (got the board as-is).
for now booting is made from flash, loading both kernel and ramdisk. i want to try nfs based booting and first strange thing i notice when kernel gets booted is that kernel parameters are always the same, no matter to what i set 'bootargs' var in u-boot. it always displays .... Kernel command line: root=/dev/ram0 console=ttyS0,115200 mem=64M .... and hangs at .... NET4: Linux TCP/IP 1.0 for NET4.0 IP Protocols: ICMP, UDP, TCP IP: routing cache hash table of 512 buckets, 4Kbytes TCP: Hash tables configured (established 4096 bind 8192) NET4: Unix domain sockets 1.0/SMP for Linux NET4.0. NetWinder Floating Point Emulator V0.95 (c) 1998-1999 Rebel.com Kernel panic: VFS: Unable to mount root fs on 01:00
although passed bootargs says: bootargs=root=/dev/nfs rw nfsroot=10.10.10.1:/tftpboot/10.10.10.1 ip=10.10.10.2:10.10.10.1::255.255.255.0:xcep:: console=ttyS0,115200 mem=64M
I also tried changing CONFIG_CMDLINE setting in .config of the kernel to same value as bootargs but still notihng changed.
If CONFIG_BOOTARGS var in u-boot is specified during compile time, does it interfere with bootargs passed at boot time ?
i will copile u-boot from CVS tomorrow (need to create new board defines), just need to clear some stuff now...
