DWM1001 update fail


I am trying to update a DWM1001 module with J-flash lite 6.14d, but erase failed.
Is the module dead or did I make a mistake? thanks

Hi Xranger

Are you using a devboard with onboard Jlink, or you own design with an external JLink debugger ?


Hi Yves,

Thanks for reply. The issue has been solved, I use a Jlink in 4 pin SW mode,
after updating a latest driver, the erase is OK.
