Hello,
I just received the MCSPTR2A5775E kit. I tested the boards when received it, and the motor was spinning toggling the switch and pressing the buttons.
The second step I tried was to upload the software, I have S32DS Version: 2.1 (Build id: 190624), I've installed AMMCLIB_v1.1.23.
Following the steps here, I used the software provided here,I have imported the project, created a new debug configuration for OpenSDA and flashed.
At this point, the motor does the alignment phase, but the software seems to get stuck: it never goes out of this while:
/* wait till SW Resolver is properly started */
while(resolver_states.state < 4){
FMSTR_Poll();
}I also tried the FreeMaster interface, and I don't see any change in the rotor angle, even if I spin the disk manually. Moreover, if I press any button after 3 seconds from toggling the switch (to allow the alignment phase to end), the motor starts to spin and then I am getting an overcurrent error. To me, it seems that there is no position feedback from the resolver.
Did you encounter this problem before?
One extra note: From FreeMaster, I am able to spin the motor using the "Scalar Control", which doesn't use the position sensor, confirming my theory.
I have also checked the resolver signals adding them to the FreeMaster page, and the SDADC seem to work fine:
Thank you,
Marco
I also believe there is a bug in the "While" I mentioned, where the code is waiting for the resolver state to change above 4; however I believe this state is never updated. A tell for this behaviour is the fact that my phase currents had always some DC offset; in fact the offset is compensated just after this while.
I simply added a call to the function that reads the resolver state within the while loop, and now the code continues and the phase currents don't have DC offset anymore, as visible below
/* wait till SW Resolver is properly started */
while(resolver_states.state < 4) {
FMSTR_Poll();
fs_etpu_resolver_get_states(&resolver_instance, &resolver_states); //Fix to exit loop when resolver is aligned
}
