Hi, sorry for posting many questions.
I’m now in trouble running this demo, and it fails when flashing to the board.
I specified ‘target’ and ‘board’ like below:
TARGET = tvm.target.target.micro("stm32f746xx")
BOARD = "nucleo_f746zg"
I didn’t make any change except the above part, but when I ran below:
################
# Run Autotuning
################
# Now we can run autotuning separately on each extracted task.
num_trials = 10
for task in tasks:
tuner = tvm.autotvm.tuner.GATuner(task)
tuner.tune(
n_trial=num_trials,
measure_option=measure_option,
callbacks=[
tvm.autotvm.callback.log_to_file("microtvm_autotune.log.txt"),
tvm.autotvm.callback.progress_bar(num_trials, si_prefix="M"),
],
si_prefix="M",
)
I got the error below 10 times.

I’m not sure what the backend is doing here, but maybe it uses west command and tries to flash the microcontrollers right?
I connected the correct board to PC, and also checked if zephyr is installed properly by trying blinky project. west command is recognized properly in current directory so I can’t find why it doesn’t work.
Could anyone help me on this?
Glad you were able to figure it out!
