Hello all, I've been struggling to get my ATSAM7S256 (on an Olimex SAM7-H256 Board) to blink, or do anythign for that matter.
For the past (I don't even know how many) months, I've been trying off and on to get started on it, using many different blink led tutorials.
Many of those were the eclipse/yagataro tools.
I found Crossstudio, and have actually connected to my arm. (I'm using an Olimex ARM-USB-OCD JTAG adapter)
Now my problem is that when I try and do anything with my target, I get an error

Thanks in advance.

Cannot halt target after resetI have done some researching, tried to change the setting on my JTAG connection, and even went the "Generic RS232 port" in Crossworks. I've tried the powerdown,test jumper+power up+10,power down, and nothing.

AT91SAM7 parts have a reset pin, NRST. Unfortunately, the micro can set the RSTC_MR control register to ignore NRST - and "ignore" is the default setting. What were they thinking?Would this have anything to do with my inability to stop the cpu after a reset? Or is it clearly resetting?
Thanks in advance.
