Difference between NRF52-DK Version v3.0.0 and v2.1.0

[YakaMein]

Hi Nordicsemi Team,

The one of our customers recently purchased NRF52-DK (Dev. Kit) which was Ver 2.1.0.

But This time has issue.

He thinks after version 3.0.0. cause the problem.


 

It seems like more switches were added and IC sized different than Version 2.1.0 2021.35 which normally working.

So, the questions are,

*He requires the information what's the differences between those models and how to make it work Version 3.0.0? 



Can you give us some advice?


Thank you so much.

Hi Takashi

What exactly is the problem with their 3.0.0 revision of the nRF52 DK?

There was one big change made from revision 2.x.x to 3.x.x, and that is that we changed the interface MCU from a SEGGER chip to one of our own nRF5340 SoCs to use as the Interface MCU (debugger). This should still work as normal though. There was also one switch added to disable or enable flow control on the VCOM port. Those should be the only major changes.

Best regards,

Simon

Hi Simonr -san

The customer said he use SEGGER Embedded Studio.

Should he use nRF Programmer - nordicsemi.com instead SEGGER one?

Since you said MCU is changed to Original nRF5340 SoCs from SEGGER chip and you may not use SEGGER Embedded Studio either,right?

We want to know how you succeeded to connect J-Link. I think software.

Can you give some advice?
