Hi,
I've been looking for a way to write to the SAM7S256 using the DBGU port. I know I need Samba in order to do this. So I'm looking for a way to boot with SAMBA. When I erase the FLASH using the ERASE jumper on the eva kit, I need to use the TST pin to rewrite the SAMBA to the flash. Is there another way to do this without using the TST pin and/or JTAG each time I erase the FLASH?
The SAM7X has a script that enables booting from ROM but the pin GPNVM2 doesn't exist on the SAM7S. Is there a similar script I can use to boot from ROM or a pin I can use to do this? I don't have access to the TST pin on my board. I would want something that boots from ROM after the FLASH is erased.
I could really use the help so thank you in advance!

hello chiko,
no there is no way to get samba active without using the TST pin.
and even if you have access to the TST pin, samba is a pain. use jtage in any case.

Thanks for the quick reply. Frankly, I hoped I was wrong...
