MPC5744P DevKit Onboard Debugger for External MPC574xP Target and Low-Cost JTAG Debuggers

KP_1999 — Tue, 23 Dec 2025 10:29:30 GMT

I have a custom board based on the MPC574xP MCU. Can I use the onboard debugger on the MPC5744P DevKit to program and debug it? If yes, how should I wire and configure it? Are there any affordable JTAG debuggers available that support programming/debugging of MPC57xx devices?

Thanks

Hi @KP_1999

The onboard OpenSDA interface is supposed to be used with the DevKit only.

A lot of customers are using these tools from Pemicro:

They have also tools for production programing:

All of them are compatible with S32 Design Studio.
