Exceptions occur while debugging thru JTAG
2004-10-28 by Leighton Rowe
While I'm debugging a device running a single EINT as FIQ and timers & uart through IRQ, I tend to get exceptions (undef, swi, prefetch, data) occuring randomly while I'm stepping through the code. Currently, I don't have any code done for these exceptions. I've also experienced data aborts whenever I use the JTAG to download, & debug code. I reverted back to ISP downloading (serial port) because of this. However, the JTAG doesn't seem to be crashing as the JTAG always shows the PC excecuting the undefined exception vectors. So, I'm not sure what could be causing these exceptions to happen. Any ideas/suggestions? best regards, Leighton
