hi,everyone.
I am using CCS5.5 and XDS100V2 debug omap-l138, this is the problem I faced:
I use the starterware example "UartEcho.c" for test. Because I also use boot.asm so The arm core is in
supervisor mode when start. And it can print string on terminal. but when I use Uart interrupt to recieve a string , I found it's not working . there is what i conclude:
1, I am sure the interrupt has occured. because when i put a char on terminal, CCS shows that the pc of arm go to a place which is very strange. Otherwise it worked well. so this means that register configuration is right.
2,I am sure The VBR and VSR of AINTC is configured properly.
3, I am sure the arm core is working in supervisor mode.
4, I think maybe it's about vector or something, but I can not find.
Is there anyone who had the same problem?
if someone can help , I really appreciate it, thanks.
