Hello,
i use a LP WiFi click board from Mikroe with a DA16200MOD-AAC4WA32 on it and as flasher + debugger probe a Segger j-link Plus.
The connection between the j-link and the DA16200 works perfectly. I can see the RTT output on Segger RTT viewer and also in e2studio telnet terminal (localhost:19021).
With a USB to UART converter connected to UART0 of the DA16200 i see the output in e2studio serial terminal. But i cannot see the output of the Printf() code lines anywhere.
I wish only to connect my Segger j-link probe to the DA16200, so i have the following questions:
1. Is it possible to see the output of UART0 about the Segger j-link emulator in e2studio directly? Because actually i need to connect a USB to UART connector and my j-link probe to my pc.
2. How can i see the output of the Printf() code lines in e2studio?
Also the question, is it recommended to use the DA16200MOD-AAC for new designs, how long will it be available?
Thanks!
Hi There,Thank you for posting your question online.

Let me check on this and I will get back to you as soon as possible.

Yes, the DA16200MOD is suggested for new designs.Please refer on: Product Longevity Program (PLP) for Former-Dialog Products | RenesasThe DA16xxx series will be available until May 2035. Best Regards,OV_Renesas
Hi There,Apologies for the delay.

You will be able to print the output of UART0 through the SEGGER RTT viewer with some modification of console.c. But the JLink will not work when the device goes to sleep. because the peripheral block is turned off.
ms said:2. How can i see the output of the Printf() code lines in e2studio?
You can see the output of the Printf() code lines through the Command Shell Console in e2studio.Best Regards,OV_Renesas
after activating SEGGER VCOM and connecting VCOM RX and TX of my J-Link to the DA16200 UART0 i can see some output when using the getting started code either in the command shell console or the serial terminal in e2studio.
The serial terminal settings are COM15, 230400, 8, None, 1.
But the output is always wrong see picture Screenshot-2025-02-28-122826 hosted at ImgBB — ImgBB

Hi There,Apologies for the delay.We have confirmed that the SEGGER VCOM works with DA16200 UART0 using the instruction from Using J-Link VCOM functionality - SEGGER Knowledge BaseNo additional settings are required.Best Regards,OV_Renesas
thanks for the confirmation!
It was my fault, because my SEGGER J-Link PLUS only supports VCOM baudrates upto 115200 baud.
See this link for max. VCOM baudrates of SEGGER J-Link probes SEGGER J-Link debug probes
