I'am doing with DSK C6713. When I run "step into" go to "memcpy" it's stop. I known't what error

0000D8E0 8087E059 [ A1] SUB.L1 A1,1,A1

0000D8E4 021436F7 || STW.D2T2 B4,*B5++[0x1]

0000D8E8 020C105B || MV.L2X A3,B4

0000D8EC 20000011 || [ B0] B.S1 0xD8E0

0000D8F0 2003E1A3 || [ B0] SUB.S2 B0,1,B0

0000D8F4 81943665 || [ A1] LDW.D1T1 *A5++[0x1],A3

0000D8F8 00000001 || NOP

0000D8FC 00000000 || NOP

I press F11 but it don' run. What do memory "memcpy" contain? Why error?

Please help me. Thank u very much.

I am guessing that in this case memcpy is a compiler built-in functon. The compiler not actually call a function but inline the code that you have posted. So stepping into or out would not make any sense.

Thanks for the reply.

Can you help me find this error? I can't not determine the cause.

Put a breakpoint on the next instruction at 0xd900, then Run.

Why are you trying to debug memcpy in the disassembly window?

You can guide me debug memcpy in the disassemble window.

I debuged window but it's run entire program not just memcpy.

We are getting too far off topic.

You do not need to debug into memcpy. You do not need to step-into this function.

What was the problem in your C program? Perhaps you should be using step-over instead of step-into for your debug. You should be using Step Over or C Step Over and not Assembly Step Over.
