Hello everyone:

                           I'm using CCS v5.4 and SYS/BIOS v6.34 debug a spi_edma program.Now I find a unknow error is:

B24=0xced15094 B25=0x25c0fb51
B26=0xc8d2d030 B27=0x55d0ab19
B28=0x20400840 B29=0xaa3c6766

NTSR=0x1020e
ITSR=0xf
IRP=0xc0002ff8
SSR=0x0
AMR=0x0
RILC=0x0
ILC=0x0
Exception at 0x0
EFR=0x2 NRP=0x0
Internal exception: IERR=0x1
Instruction fetch exception
ti.sysbios.family.c64p.Exception: line 248: E_exceptionMin: pc = 0x00000000, sp = 0xc001a3a8.
To see more exception detail, use ROV or set 'ti.sysbios.family.c64p.Exception.enablePrint = true;'
xdc.runtime.Error.raise: terminating execution

But I didn't make anything for those module.

Who can help me ???

    Have you look at the site? http://processors.wiki.ti.com/index.php/SYS/BIOS_FAQs#4_Exception_Dump_Decoding_Using_the_CCS_Register_View

    Also, you might need to increase the size of the SysMin buffer. It looks like you are losing some of the dump. You can increase it. For example, the below code in the .cfg changes it to 4096 bytes.

    var SysMin = xdc.useModule('xdc.runtime.SysMin');
    SysMin.bufSize = 4096;
    System.SupportProxy = SysMin;
