I am using ULINK to debug the LPC2132 board. They work well for some days. But now a problem appeared. Everytime I want to download code to FLASH, always get"Could not stop ARM device, please check your JTAG cable?" But JTAG can be detect on Option for device. I do not know what is wrong? Thanks in advance for any idea.
I had the same problem when i got some new 2138's (with them all) and my old one's, based upon 2132 worked fine. I've tried to change max. JTAG clock to 500kHz and it works. And then i changed i back again and it still works. I don't now the reason for this.
Yes originally the method I quoted earlier worked for me. However the problem has come back and I can't fix it. I'll have to take a look at the JTAG disabling thing...
