I have another startup-related problem with an at91SAM7 family CPU; hopefully you guys can help.
The demo worked fine right away on my dev board (the standard atmel S64 board), but it crashes about 2/3 of the time on my S256 board (custom made, but similar to the dev board). I’m pretty sure the hardware is ok, since I’ve been running other code on it for months with no trouble.
When entering xTaskCreate for the first time, one of three things will happen:
1. jump to AT91F_Default_IRQ_handler (an infinite loop)
2. jump to dabtvec (Data Abort, another infinite loop)
3. Successful completion (runs fine)
I haven’t found any way to predict which one I’ll get, although I only get successful completion with the JTAG connected. Without it, the board just continually resets.
