OM13098 Can program over segger but not Link2

[whinis]

I am having an odd issue on my OM13098. After the first programming with the RNG example I am unable to use MCUXpresso to program the board again over Link2. Link2 appears active, I can put it in DFU mode and program it with CMSIS-DAP using LPCScrypt. I can also access the UART over its VCOMM and have confirmed that UART is working as I can put the board into ISP0 mode and wipe the ROM.

I can also confirm SWD is working as using a Segger JLink on P1 allows me to use MCUXpresso to write the LPC54628.

Using Link2 gives me this error

Unable to open probe index 1.
Error: Probe not open

Also D10 keeps blinking.

Have you re-programmed it with LPCscrypt back to a CMSIS-DAP probe and the jumper JP1 removed?

[whinis]

I did, it was one of the first things I tried without success

Hello,

How about program  it with LPCscrypt   to a jlink probe ?

If all can't work, maybe the debugger on your board broken.

So previously I had no issue programming it atleast in debug mode, now that is not the case after having programmed a few times using my jlink. It enumerates

However my usb tester says its broken in some way

Small update, after unplugging and replugging 5-10 times I got it to flash to jlink and that worked flawlessly then. However reflashing to CMSIS-DAP continues to not work.

[Alice_Yang]

How about change to  another PC to test ?

[whinis]

Sorry been busy with life and I don't seem to get emailed from these threads even though its checked. Will need to debug that at another time.

Using another PC did not work and now even using a JLink has stopped working. I  can connect to the debug header and appear to have a connection as the JLink shows voltage. However I cannot connect to the core. I can still flash over USB MSC however I can no longer debug.

Thought I replied to this earlier, neither deleting the launch file nor starting a new workspace fixed the issue.

[Alice_Yang]

OK, thanks for your sharing.

[whinis]

Is there anything else for my to try or is my board broken in some way ?

[Alice_Yang]

Hello whinis,

How about change to a new workspace, open a new project, then click the "Debug" button under "Quickstart Panel" view :

[ErichStyger]

have you tried deleting the .launch file for the LPC-Link2 already and create a new & fresh one?
