We got new Nano B01(ex:SN:1423019138891) and the Nanos failed to boot.
As We used a Nano with a SDcard which worked well on our previous Nano board(SN:1423219075767),
and Nano launched failed.
However, the Nano (ex:SN:1423019138891) worked well after be re-flashed by using SDKManager.
It’s similar with the previous Nano A2 issue.
Is there a way to fix it?
Thank you for any advice,
