Debug problem on certain memory block using ccs5.5 for c5517

Vava

Hi all,

I just found another Problem on debugging our custom c5517 board. the different from our previous custom board that used c5517 is we change the use of i2s with mcbsp.

other modules run perfectly the same, but only the mcbsp has some Problem in Debugging. as we know that the Register of mcbsp setting starts at 0x4000. the debug always shows error by:

C55xx: Trouble Reading Memory Block at 0x4000 on Page 2 of Length 0x1: (Error -1143 @ 0x4000) Device core was hung. The debugger has forced the device to a ready state and recovered debug control, but your application's state is now corrupt. You should have limited access to memory and registers, but you may need to reset the device to debug further. (Emulation package 5.1.507.0)

further Information:

ccs that we use is . ccs v5.5

Compiler 4.4.1

and jtag Debugger: xds100v2.

thank you in advance.

best regards,

vava

Suggest to check the cMcBSP module clock is on. Such as McBSP clocking gating bit in PCGCRL.

Hi Vava,

Could you confirm the McBSP clock stop request is deasserted, as shown below.

hMcbsp->sysRegs->CLKSTOP1 = (Uint16) (((hMcbsp->sysRegs->CLKSTOP1 & 0xFFBF) | 0x0000));

Also, suggest you to probe McBSP register once these Clock Setting are taken care. You shouldn't see the error - "Trouble Reading Memory Block at 0x4000" .

Hope this helps.

Regards

Hallo Vasanth,

thank you for your Suggestion. here I dont use the library of CSL, but the declaration that you mention is written already.

I tried to not run the program (the pointer of debug still stands on void main(void)) and the error is already there. We suspect that the mistake Comes from the initialization. So far I use the gel file C5517.gel that is provided.

Thank you.

Regards,

Vava

Hallo Vasanth and Steve,

i decided to try the CSL library, and now the McBSP is okay. I have not found what's wrong with my own code, but at least now I have a right reference to continue working.

Thank you so much :)

best regards,
