I am using DA14531MOD with Keli uvision5.
I was able to connect ULINK2 with JTAG and run it in debug mode, so I want to write code to flash and use it. Where should I refer to for necessary settings?
You can get tutorial here UM-B-083 SmartSnippets Toolbox — UM-B-083 (renesas.com)
I'm trying with Smartsnippets toolbox, but this error occured:
No known chip found while opening JLink connection.
I used ULINK2 with serial wire mode interface.
What is the issue?
Thank you
Hi Yoshihiko,
DA14531 reset is active high, the reset pin shows in the picture is active low. This may be the problem.
you can place a mosfet for voltage transform.

I tried with MOSFET, and this error occured.
I can use debug mode of uvision5 without MOSFET circuit.
Is this really issue of connection?
Just make sure the reset pin is positive active is ok.
could you share the screen shot of the tool box, and the connection picture of your device.
Thanks

Connection is here
I check J10, then it shows 2.2V
The screen shot of the tool box
Are you sure the ulink's reset is positive triger?
this pin should be low as default.
It is default high.
Now, I changed like this:
I click "connect" in the tool box, then reset pin become higt.
But error occured like this:
There is no reason that you can use keil for debug but can not using tool box for connection.
try to switch like this and have a try, since the reset of jlink is an input.
