CRD25DA12N-FMC v2.0 Firmware

Hello,

I downloaded the v2 firmware and tried running it on the v2 PCB, but I did not get any output.

I changed the modulation factor to 0.5f and debugged anything that could be wrong on the hardware-side, but no luck (I am applying 100Vdc and have 3-ph inductor loads for an initial test).

After debugging the software, I believe the problem is the CLA task is not being triggered. (As a simple test, I tried toggling an LED both in the ePWM1 interrupt and the CLA interrupt. I saw the red led light up for the ePWM, but not for the CLA task).

I tried a few additional steps to ensue the CLA was properly being initialized, etc. but so far no luck (I am not an expert in embedded software though)

Have this v2 firmware working w/ v2 board been comfirmed to work at this point?

Thanks!

    Hi tjdonne,

    I can confirm that the V2 firmware works with the V2 board. We perform system-level burn-in at full power before we ship every CRD25DA12N-FMC unit, so the unit should be in a functional state when it is received. Would you be able to provide a few more details of your system testing? Supplying images would also be very helpful. For example, are you able to communicate via CAN? Which CAN adapter are you utilizing? What is the value of your inductive load?

    Best Regards,

    Austin C.

    Thanks for the reply Austin C.

    I was wrong about the CLA task not running, everything in the v2 firmware is great!

    The problem was instead of controlling the inverter via the CAN interface, I was deploying/monitoring the c2000 via code composer studio (CCS). I am going to be modifying the code for closed-loop control for my project, so need to deploy new code this way.

    To future viewers also using CCS: ensure GATEDRIVE_DISABLE gets set low to enable the inverter :)
