Linux/AM5728: JTAG fails to connect to DSP

Part Number: AM5728

Tool/software: Linux

Hi,

I am using AM572x EVM and have problem connecting to C66x using JTAG. I am able to connect and load the code to all cores with JTAG. But when I have Linux running on A15, when I tried to connect to C66 cores, JTAG always complains that 'the core is held in reset'. I am using the standard image for SD card created by Linux SDK. And I believe there are codes for both C66s that are loaded into the C66 by the boot loader.

Here is my question: How can I connect ONLY to C66 using JTAG while Linux is running on A15?

Thanks
