@cek Deer cek,
Thanks for the quick response and kindness.
In the past, IMU values could be read using the 300ZI EVK.
But, there was a problem that I could not connect to the IMU Server.
I tried to fix the problem by modifying the firmware, but now I cannot read the IMU values.
In my personal opinion, the firmware (or image) seems to be corrupted.
I want to check or fix the cause of the problem, what should I do?
P.S. 330ZI (X) -> 300ZI (O)
