Hello,

thanks for reply,

this patch is very good in general, but the problem is that the function nand_boot() is never called in my architecture. I use a AT91SAM9G20 from Atmel [ARM9].

Do oyu have another idea ?

Thanks a lot Manuel

Hello,

I want to use the "silent" paramter of ubbot in a dynamically way. The problem is that I use a Nand Flash to store my uboot paramters.

When the function env_init is called only the default enviroment is linked as the actual enviroment. After env_init the serial console is initialized and the banner is printed.

I want to read out my actual uboot paramters from NAND to check the silent paramter before any character is sent through the Serial-Console. I placed the functions nand_init(); and env_relocate(); into the function env_init, buth that desn´t work. (I think there is always a reset ?!)

Doesn't this patch help:

You mean you boot from another memory (NOR) and have your environment in NAND? I think, this is one of configurations, that we said noone would ever come up with... Maybe I'm wrong though, see if others correct me.

Hello, all is inside the NAND flash,

0x00000 First Level Bootloader (which loads the UBoot from 0x20000 to RAM and execute it) 0x20000 UBoot 0x60000 UBootEnviroment 0x80000 UBoot Enviroment Rendundant

So have a look at /lib_arm/board.c The function nand_init() and env_relocate() sre called too late for the "silent" flag.

I tried to place the functions nand_init() and env_relocate() into the function env_init(), but that crashes...?

Thanks for help Manuel
