Walnut PI 1b

Hello I have a new Walnut PI 1B. Tried to flash the 32Gb SD card the ““2025-3-6_V2.5.1_WalnutPi-1B_6.1.31_debian12_desktop.img”” , with BalenaEtcher, like have done many in RaspBerry´s.

Then the Walnut start, but keeps rebooting, and never end the sart up. I can see it in HDMii out, the rebooting, and keep rebooting,rebooting.

What can this be ?

it was the power supply, not amp enought.
