Hello - I was recently porting some old U-Boot scripts to my new board and I was having a problem with the kernel command line. Instead of getting substitutions for things like $(ipaddr), I was seeing, literally, $(ipaddr) in the kernel command line as reported by the kernel. I also saw a similar problem with the U-Boot tftpboot command.
This: Ant2> setenv load_kernel tftp $(loadaddr) $(kernel_image); Ant2> run load_kernel
Gives this output from U-Boot: Ant2> run load_kernel TFTP from server 192.168.0.100; our IP address is 192.168.0.10 Filename '$(kernel_image)'.
While this: Ant2> setenv load_kernel tftp $loadaddr $kernel_image Ant2> run load_kernel
Gives this: Ant2> run load_kernel TFTP from server 192.168.0.100; our IP address is 192.168.0.10 Filename 'kernel.uImage'.
Which works.
I checked the DULG, and the guide indicates that the first form shown above is correct. Have things changed or do I have something misconfigured? Any ideas?
Thanks,
Keith
