I found the solution.

for anyone that is interested with this topic also, here is the explanation.
I compiled the AI model with Vitis AI 2.5, somehow the other versions like 3.0 and 1.4 does not work with DPU overlay in kv260. the arch.json for default kv260 consist of this line of word

{
    "target": "DPUCZDX8G_ISA1_B4096"
}

If you modify the architecture of DPU into B3136, then you need to change arch.json with this

{
    "target": "DPUCZDX8G_ISA1_B3136"
}
