[bahubali-bg]

Dear Sandeep,

When we trying to flash nRF52840 dongle with openthread FTD hex file, We got prompt to select soft device id, we have tried with various soft device ids like s140,130 etc. But we are getting below error,
Failed with exit code 1. One or more program tasks failed: * CFE82E07A57F: [sdfu] , code: SdfuExtSdVersionFailure. Message: Failed, [sdfu].

Please let us know how to resolve the issue.

Thank you.
