SBL1360A issue

SBL1360A issue was created by Inounx

I am trying to test the SBL1360A with a brushless motor without hall sensors. So far didn't get any good results.
I tried to use trapezoidal mode, run the motor/sensor calibration (motor turns during calibration) but does not run after when I select a command.
The motor has a built in resolver, I wired it to the SBL1360A and tried the sinusoidal mode with resolver feedback, the calibration make the motor turn slowly (maybe 4 turns back and forth). After that when I send a command, the motor turns a little then stops, current stays constant but no more movement. The resolver value seems to work, (I ploted it with roborun+) but it's noisy (the signals ASIN and ACOS seems good when viewed with an oscilloscope)

I am king of lost between the controller manual and the roborun manual: some explanation on how to setup the controller does not match, and the descriptions are not clear at all. Moreover the displayed software version of the controller is v2.0 beta. On the download page there is no firmware for SBL1360A (only 1360 not "A"). Is this a bugged version ? do you have a new version ? More clear setup explanations ? Before digging deeper into this problem, I would apreciate some hints / advices.

The SBL1360A is not capable of sensorless commutation.

the manual says
• Trapezoidal Sensorless (A-version)
on page 1
Its very confusing. I bought this module for driving a BLDC motor with no sensors!
