Hi
I would be grateful for some help with environment variable substitution in
U-Boot please.
I have:
=> printenv
[snip]
bootargs=console=ttyS0,115200 root=/dev/nfs rw
ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:${netdev}:off
nfsroot=${serverip}:${rootpath}
[snip]
bootcmd=run flashboot_nohv_mount_nfs
[snip]
flashboot_nohv_mount_nfs=setenv bdev /dev/ram; run bootargs; bootm $kern_flash
$rfs_flash $fdt_flash
[snip]
ipaddr etc. are also defined.
When I leave the system to autoboot I see:
[ 0.000000] Kernel command line: console=ttyS0,115200 root=/dev/nfs rw
ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:${netdev}:off
nfsroot=${serverip}:${rootpath}
So environment variable substitution is not happening.
What am I doing wrong please?
Best regards
David
