Please describe your issue below:

Hello @numbqq, @Frank,

I’m facing compatibility issues with the new version of Khadas Vim3 v14.

Until now, I used Khadas Vim3 v12 with models using NPU under Xubuntu 18.04.

After this new v14 version, the flash of the old Khadas no longer worked, so I built a new Xubuntu 18.04 OS.

If I understood correctly, the new build uses (mandatory?) Acuity 6.0 (previously I used Acuity 5.7), therefore my old models converted to “.nb” can no longer be used and must be re-converted.

My questions are:

  • Can we build an Xubuntu OS for the Vim3 v14 using Acuity 5.7 in order to use the old “.nb” already converted?
  • If not, is there a method to directly transform “.nb” v12 to “.nb” v14 so that there is no difference in the model outputs?

Thank you in advance for your response.
