Hello all, I am having issues with getting the motors working. I have flashed the microdriver according to the guide and also ensure I use the ‘flash’ option and not the ‘release’ and I try to get the motors working but no response. What could be the issue? and how can I resolve this?
HOw do I even verify that the microdriver was successfully flashed? According to the COde COmposer software it looked successful and went into debug mode.
@felixwidmaier please I need your help. When I tried to debug the driver code running, after few lines it enters ‘pie_illegalIsr’ mode. THe line that tries to run before entering this mode is:
estHandle[HAL_MTR1] = EST_init((void *)USER_EST_HANDLE_ADDRESS, 0x200);
The illegalIsr is not returning. How can I fix this. Thank you.
sorry for not responding earlier!
I’m afraid I can’t help with the
PIE_illegalIsr, I don’t think I ever ran into this.
From the motorware documentation (which comes together with the code, see “…/motorware/sw/drivers/docs/api/f2802x/html/index.html” in your workspace):
Defines an illegal interrupt service routine - if the program pointer references this function, there is an incorrect mapping in the PIE interrupt table.
I don’t know what might be causing this, though. Did you make any modifications in the firmware code?
Since this seems to be an issue with MotorWare, you may also try asking the Texas Instruments support.
Regarding your initial question testing about testing if flashing worked: Are you connecting to the board directly via CAN or are you using a master board?
I hope this helps.
