cable is locked in JTAG-based Hyperterminal

[hulkakos]

Hello,

I have implemented an architecture with microblaze 7.10.d in EDK 10.1 and I have downloaded a linux image. As an output I am using the mdm uart. When I am trying to boot linux  ( with command "run" in xmd console) in the JTAG-based Hyperterminal I have this repeated  message: Info:Cable is LOCKED. Retrying... Does anyone have any idea what may cause this?

Thanks in advance

The tools typically do lock the cable such as when I used Impact to download the bitstream, it locks the cable.  I have to tell Imact to release the cable or I get that from XMD.

I'm not sure how you downloaded the bitstream but it sounds like the same issue.

Thanks.

I have downloaded the bitstream from EDK (Device Configuration ->Download bitstream) and then I open a xmd terminal and I download the linux image from xmd. For the output I have another xmd terminal that is connected with the mdm uart. So when I start the microblaze I have the message "Cable is locked" in the mdm uart terminal.   Should I use two separate xmd terminals ( one for downloading the image and the other one for mdm uart) or I can do everything in just one xmd terminal?

Thanks in advance,

Nikos

From the first XMD console, are you using the "terminal" command to open up a dedicated terminal window?

[hulkakos]

Yes, in the xmd console that I use for mdm uart I type "connect mdm -uart" and then "terminal". After that I use the other xmd console and I type "run" and the message about the cable appears in the first xmd console that I use as mdm-uart.

You should only have two windows open - first open XMD and connect to the processor normally. Then run the terminal command and another window will open for the terminal. Then you should be able to download your code,  modify memory, etc. from the first window..

It works. Thank you very much.
