JTAG and DSP Bootup Problem

Started by wei Wang September 18, 2006
Dear all,

Now I am debugging DM642 Board which is designed and layouted by myself, when I want to connect my board to CCS, there occurs problem that CCS cannnot initialize target cpu.

After carefully examing my board, I found that this problem is caused by DM642 cannot quit RESET state after pluging power supply, but I have configured all necessary dsp pins for device boot configuration such
as CLOCKMODE, BOOTMODE, LEDIAN, MAC_EN etc.

So is there any one that can tell me why and hoe to fix it? Thanks very much!

Best Wishes

Dear Wang
I have worked on PEP5416 a version of DSK5416 and have faced the same problem of "CCS cannot initialize the target CPU".
The way I figured it out was through the GEL files. After loading the required configuartion in CCS through the StartUp, I reloaded the GEL files (after the CCS opens). And then the device was working.
I hope it works for you.
