Non-experimental U-Boot compilation
Dear all,
???? I am using the AT91SAM9G20EK kit and want to port Linux on this. I am using the AT91SAM9260ek configuration as it seems the closest. The problem is after building the U-boot with the sources for this board, generating the .bin, loading and a power on reset (POR), there isn't a command prompt exposed (u-boot>). After POR, 1 1 2 1 1 2 continuosly prints on the hyperterminal. I read from AT91.com that this is the expected behavior for the demo version. What is rge procedure to get the prompt ? Are there any separate configuration settings?
Please help as I am stuck.
Thanks & regards
Sandeep.

Try to define CONFIG_AT91SAM9G20EK in the board configuration ;)

Dear Reinhard Meyer,
Appreciate your quick response. I had done this earlier before posting this mail, but with the same problem:
step 1) export PATH=$PATH:/work/arm/4.3.2/bin step 2) make distclean
step 3) makeAT91SAM9260ek_config
step 4)make
Can you please help me further, please.
I can't help you with the following tasks:
1. find out what are the differences between 9260-EK and 9G20-EK ?
2. find out what subtle differences might exist between 9260 and 9G20 SoC?
It might be more than "AT91SAM9G20 = 400MHz version of AT91SAM9260"...
And I can't see in above transcript where you set the #define I mentioned.
"#ifdef CONFIG_AT91SAM9G20EK" exists in various places in the source, but I do not know if that ever was a really working port or just someone starting on it.

Dear Reinhard Meyer & All,
?????????????? Apology for not sending to the mailing list; forwarding the same to the mailing list. There is already a #define CONFIG_AT91SAM9260ek 1 in /include/configs/at91sam9260ek.h. I will check further.
Please help me if you have any clue further.
Thanks & regards
Sandeep Suresh.

#define CONFIG_AT91SAM9G20EK !!!
I think you would have to define this additionally to or instead of.
If that does not help, you have to investigate yourself what the diffeences are.
