error cu[0] timeout

[Yuxin-Yu]

Hi, I want to test the functionality of the DPU separately, so I set the number of softmax in the DPU to 0 and built a testing process for "DPU+CPU softmax" based on the CPU softmax test code. However, during the running process, an error occurred after enabling the DPU. It seems that my DPU hardware did not start running. What may be the reason for this?
