vx4 tests fail on linux agent #301
Description
test_thdn.py::Test_BasicMicArray::test_thdn_OneStageFilter[1stg-python_xcore] and test test_BasicMicArray when run with 16frame-8n_mics config (for eg. test_BasicMicArray[16000-0mo-0isr-16frame-8n_mics]) fail for the vx4 target when run on the sw-hw-vx4-exp0 agent.
The tests pass when run on my Mac.
I've debugged and found the issue to be in data sent from the host to the device over xscope.
As a workaround, I've found that adding a small delay before xscope_ep_request_upload() call in xscope.py fixes this.
PR #300 adds a delay of 0.1ms before the xscope_ep_request_upload() call.
