How to create configdb entry for debug to conect to coresight using D-STREAM. I put ARMCS-DP in scan chain and try to configure.

Hi,

I am trying to  create configdb entry for debug to conect to coresight using D-STREAM. I put ARMCS-DP in scan chain and try to configure .

Debug hardware config tool complains Coresight ROM table has failed - failed to read confi item DAP_CONFIG_INFO.

To debug furhter I used CSAT command line tool. I am able to read version ID and power up the DAP..

Here are the commands.

1) Con usb  (connect to DStream)

2) chain  dev=ARMCS-DP clk=20000  (put coresight in JTAG chain)

3) dvo 0  (This should print the ID)

4) drw DPACC.CSW  0x5400000  (Power up DAP)

5)  drr DPACC.CSW  (Please  let know what you read back.)

I am using ARMv8. I want to use dmr command to read some memory location but CSAT doesn't take more than 32 bit addresses.

Any ideas how to overcome this hurdle.

Thanks in advance.
