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?
Hi Yoshihiko,
Thank you for posting your questions online.
DA14531 does not support keil flash loading, please using smart snippets tool box. or smartbond-flash-programmer

Thank you
Do you mean that in order to use DA14531 independently of PC, Keil uvison alone is not possible?
yes, but you can use e2stdio IDE with our latest SDK version..
Thanks,
Because the DA14531 series' flash is not on-chip, it is plugged as peripheral. customer can select different kind of flash or eeprom for booting. So, it is not generic drive-able by one flash script.
I try to install smartbond flash programmer, but I cannnot.
The situation is the same when running with administrator privileges.
And more, what is the easiest way to boot with Flash on the DA14531MOD?I am using SPI to communicate with the sensor. Can I still boot with SPI Flash?
yes, the spi can be used after booting.
you can find boot details here.

Thank you for teaching.
Do you have any idea about trouble of installing smartbond-flash-programmer?
could you try another PC, it works well my site. with Windows 10 English edition.
Personally, I recommend smart snippets tool box. it's more powerful.
I try with 2 PC, but I cannot.
Where should I look for how to use smart snipets tool box?
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?
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
