Hi segger experts，

Recently, I've met the following case and i've no idea to fix that, could you please help check that?

Issue:
If I choose the official RV32 as the device for my risc-v platform, then it can be accessed via Jlink-cJTAG; but if I define my own device name in the JLinkDevices.xml file, it cannot be accessed.

Steps:
1. Select the official RV32 as the device.

2. You could see my risc-v platform can be accessed via cJTAG.3. Now I add my own device into the JlinkDevices.xml, meanwhile named the Vendor is "VendorTest" and the device name is "TestDevice" just as the following shows:


4. Select the TestDevice.


5. My risc-v platform can not be accessed!
I need to add my own device name into the JlinkDevice.xml so that I can use my flashloader, but now it sees there exists problem to access the risc-v core via cJTAG in such way .

Have you met such issue before and how to fix that?

Thanks in advance,

Gavin

Hi segger experts,
I notice that the jlink cJtag accesses to core successfully, the ConfigTargetSettings() would be done before access core, but if choose my device from JlinkDevcices.xml, there has no such operation and the jlink cJtag can't access to the acore. Maybe that is reason. So could you point out what does the ConfigTargetSettings() do to risc-v core?



Thanks a lot,

Gavin

Hi Fabian,

Thanks your reply and I've tried with wiki.segger.com/J-Link_cJTAG_s…cs#Short_connect_sequence.
Now my device can be accessed with J-LINK cJTAG.

Many thanks agagin!
