[En-Nut-Discussion] Porting NUT/OS on the AT91SAM9xe512

[hsx]

Hi ole:
Thank you for your reply!
First，I say that I use the NUT/OS version is 4.9.9.
I want to say something about porting NUT/OS on the AT91SAM9260 and AT91SAM9xe512。
first question:
I use the AT91SAM9260 board that is made by myself. The two HY57V561620FTP-H are used for SDRAM. Uploading a binary(include NUT/OS) to the AT91SAM9260 SDRAM via SAM-BA works normally.
I use the AT91SAM9XE-ek board that is got from ATMEL company. The two 48LC16M16A2 are used for SDRAM. Uploading a binary(include NUT/OS) to the AT91SAM9XE-ek（AT91SAM9xe512）SDRAM via SAM-BA doesn't work.
In the ChangeLog file( 2010-08-02),you say "arch/arm/init/crtat91sam9260_ram.S: Uploading a binary to the
 AT91SAM9260-EK SDRAM via SAM-BA doesn't work...." . The problem is tha same with  my AT91SAM9XE-ek board from ATMEL company. Is there a problem with ATMEL's board,you think?
second question:
I want to run NUT/OS in internal flash on the AT91SAM9XE-ek（AT91SAM9xe512）, How to use SAM-BA to load program to the  AT91SAM9XE-ek（AT91SAM9xe512)?
third question:
You said thar you can achieve to run NUT / OS in SDRAM and internal flash on ETHERNUT 5. I want to know which linker script / startup code are used for you? Where can I download?
Any help will be appreciated.
Best Regards,
