VIM1S not working at all

Hello,

i’m trying to boot a VIM1S, but oowow is not working at all,
i see with hdmi output just the oowow sign and no network cable,

can anyone point me to a solution please ? i tried to upgrade the spi flash too.

i built a debian distribution with the fenix tool, but vim1s does not boot at all…

please help me, i have ten of these for a project laying on the shelf !

Can you follow the user manual to boot into OOWOW with PRESS the Func key ?

  1. try get some logs from UART serial console
  2. led indication
  3. try boot from from SD write image to sd http://dl.khadas.com/products/oowow/system/vim1s-oowow-latest-sd.img.gz
  4. check more information about OOWOW [Khadas Docs]
  5. if nothing works return or change device please
