[U-Boot-Users] Query about U-Boot NAND ENV section

[Hiremath, Vaibhav]

Hi,

 

I am using U-Boot 1.2.0 release of U-Boot and working on ARM1176
platform. I have ported U-Boot for my platform, which boots from NAND
Flash, save ENV variable onto NAND Flash. Almost everything works fine
for me till now. But today I came across one issue - 

 

When I set baudrate to different value from U-Boot prompt, and do a
"saveenv", and after that if I reboot the system it should boot with new
baudrate set. Ideally it should take new baudrate, but it always
configures default baudrate.

 

I tried to dig into this issue, and found that, U-Boot for NAND Flash is
designed the same way. The function "nand_init" gets invoked after
"env_init" and "serial_init", and sue to this U-Boot always uses the
default baudrate. 

 

Do I understand it correctly? Is there any way to resolve this issue?

 

Thanks,

Vaibhav
