@neuropilot-captain can you have a look?

I think the buck version should be set correctly if you install executorch. MTK backend didn't use speicalized buck, but the same as the executorch buck

@Vinaysukhesh98 Which Neuropilot Express SDK version did you download? Switching back to the older one could solve this problem
