Hi,

I've the same problem as Lizongfang.

Jtag device is not mIDASLink but a updated J-link from Segger. Keil is V4.72.10.

Here some output:

 

Info: ADI system TAP: Connecting to device with system TAP.
Info: TotalIRLen = 5, IRPrint = 0x11
Info: Analog devices system TAP: Enabling CPU core.
***JLink Error: ADI system TAP: Could not read CPU core Id.
Invalid core Id. (0x00000000)
Trying to connect with 5 kHz !
Info: ADI system TAP: Connecting to device with system TAP.

Info: Analog devices system TAP: Enabling CPU core.
***JLink Error: ADI system TAP: Could not read CPU core Id.
Invalid core Id. (0x00000000)

 

Any suggestions?

Thank you
