Recently, we have been speaking with NXP to find some good candidates for a series of roadtests they would like to sponsor. The first product we've talked about is a reference design board (RDK) that's capable of controlling three sensorless-based PMSMs (Permanent Magnet Synchronous Motors), one direct current (DC) motor, and four valves under low CPU loading. I think there's a lot to do on a roadtest of this product and wanted to get your opinions.
I'll add some basic facts about the RDK below.
If you have the time, I'd appreciate you voting in my polls, too. Thanks.

Here are some basic facts about the board:
The MCTPTX1AK324 is a reference design board engineered for out-of-the-box automotive multi permanent magnet synchronous motor (PMSM), targeting electric pumps, electric powertrain, eTurbo or thermal management system controller applications. Based on the 32-bit Arm® Cortex®-M7 S32K3 microcontroller and the GD3000 pre-driver, it controls three sensorless-based PMSMs, one direct current (DC) motor and four valves under low CPU loading.
Here are some features of the board:
- Supports up to three PMS motors sensorless field-oriented control (FOC)
- Up to 100W power for each PMSM
- Up to 20W power for DC motors
- Up to 5A peak current for high-side switch
- One-way CAN and one-way LIN
- Dual-core operation mode to reduce CPU load
- ISO 26262 support
Here's the block diagram:
