Is it possible to get a homemade board to work with MCUXpresso?

[christian_gross]

Hello,

Well as the topic states, Is it possible to get a homemade board designed around a chip like LPC51U68, to work with MCUXpresso IDE?

Best regards,

Christian.

Hi Christian

If the board is designed by you, we can use MCUxpresso IDE connect it, but we must use it supported target interface.

Our recommendation is LPC-Link2, see:

Have a great day,

Thank you for the answer.

So it is not possible to connect my own design board to MCUXpresso via USB like boards from NXP?

Hi Christian,

it depend what you mean: if this is about debugging, you need some kind of debug probe. So if you have added the JTAG/SWD debug header to your own board, with the help of a debug probe you can use it with the MCUXpresso IDE. All what you need is to use an external debug probe, e.g. a LPC-Link2, a SEGGER J-Link or P&E Multilink. Or you could add/embedd say the LPC-Link2 debug circuit to your board too.

I hope this helps,

Erich

Hello Erich, thank you for the answer.

I have the LPC-Link 2 board, so that is one way, adding the JTAG/SWD debug connector too my board. But it would also be nice to have the LPC-Link2 debug circuit.

I am building a board around the LPC51U68 MCU, so if I wanted to add LPC-Link2 debug circuit, would it be correct to have a look at the LPCXPRESSO LPC51U68 EVAL BRD? Are there any app notes on embbeding LPC-Lind2 debug circuits?

Hi Christian,

Yes, I would look at that board as a reference design. Personally I would stick with a JTAG/SWD connector and use an external debug probe for a custom board because this reduces design complexity and BOM cost. As for an application note on embedding the LPC-Link on your own board: I have not seen something like this when I searched for it, but maybe someone else is aware of it and can respond.

I hope this helps,

Erich
