Programming and Debugging a third party module.

[Dhyey Sejpal]

Hello,

I have a Taiyo Yuden EYSHSNZWZ module. I also had a breakout board manufactured for it to get access to all the pins. I am having trouble trying to program the chip. I saw the datasheet for the evaluation board for that component and it says a J-link Lite is needed to load programs onto the chip. If so, are there any J-link modules available that I can buy to bootload my chip?

Otherwise, do I need to buy the entire EKSHSNZWZ evaluation kit to test code on a reference board and then program my chip? Or can I use the NRF52-DK to test code and program my external chip? Will I face any difficulty in running the code as the chip on the NRF52-DK is a pure NRF52832 whereas what I have is a third party module?

Any help is greatly appreciated.

Dhyey.

The chip has an ARM-Cortex-M4; so it can be programmed with any SWD-compatible programmer.

The advantage of a J-Link - any J-Link - is that Nordic support it with their tools, and it is widely supported by 3rd-party IDEs - including the free Segger Embedded Studio (SES).

Nordic provide example projects for use in SES.

You don't need to,  but it is always wise to have the manufacturer's development kit - as they will be best placed to support you on that, and there won't be any doubts about possible issues with your own board.

Yes.

In fact, you may be better with the Nordic DK,  as you then have all Nordic's example projects ready to go on it.

No more difficulty than in porting anything from one board to another.
