Segger JLink Firmware Update fails

When trying to use Segger's JLinkExe it says, that there is a new firmware for the onboard J-Link OB-SAM3U128. When I do the update, it always fails at 98% with the message:

ERROR: Communication timeout. Emulator did not re-enumerate.
ERROR: Firmware update failed.

Flashing binaries with the dialog SDK (which uses JLink with JTAG itself) works.

What could be wrong here? Were can I investigate?

Hi ZephraimMcKladden,

Hi ZephraimMcKladden,

Thanks for your question online. Could you please indicate if you are using any of our Development Boards?

Are you able to program the DA1469x after the update fails?

Thanks, PM_Dialog

Well, because I select all

Well, because I select all the relevant values in the comboboxes, when creating an issue, I thought my selection would be visible.
I'm using the da14695 DevKit and as I wrote, programming/flashing is not an issue, it works, also after the failed update try.

Only the update of the JLink-OB Firmware failed.

BUT: Meanwhile I tried the same DevKit with JLink.exe on a Windows PC, and the update worked without any complaints. I don't know the original reason for the failure though, as this doesn't seem to be deterministic behavior :-(

Is it possible that USB-hub effects may be a reason here?

Hi ZephraimMcKladden,

Hi ZephraimMcKladden,

Glad that you got it working. Yes, probably the USB-hug might be the root cause. I’d suggest you connect it directly to you PC rather than using a USB-hub.

Thanks, PM_Dialog
