Hi Experts,

Good day!

Please assist us on this customer's concern.

66x core 0 is not connect success However, other DSP cores can be connected successfully. The ARM core cannot be connected successfully, but it is indicated that it is running.

may I ask why this security setting prevents the bebug? I just want to know if the reason is our hardware design or the chip itself.

Any information that can help is much appreciated.

Regard,

Jonathan

Both the messages are true.

It means, it was connected and it was running.

But while running, the connection between the JTAG on the board and the PC got disconnected. This may be due to power cut ( I.e., Power off) on the board side.

Once the disconnection happens the CCS console detects the disconnection and displays the error message.

Since the disconnection happens, the debug window cannot receive any communication, it just stand still.
