Hello, I am using the Dialog Semiconductor DA14531 Tiny module which I programmed with the SDK6.0.16.1144 from DA14531 - SmartBond Ultra-Low Power Bluetooth® 5.1 System-on-Chip | Renesas by following their getting started tutorial. I am using the Keil uvision5 software and opened the "project/target_apps/ble_examples/ble_app_peripheral/Keil5/ble_app_peripheral" project.
With my ble module plugged in (through USB), I compiled the project in Keil5, started 'debug' mode and started 'run code execution' successfully and I could detect the ble module from my smartphone.
Next, I used the SmartSnippets Toolbox and burned the hex file (I got from compiling the ble_app_peripheral project from Keil5) to the device and received a 'burning was successful' prompt.
The problem started when I made some changes to the ble_app_peripheral project and wanted to test it in the device, when i tried to start debug mode again, Keil5 gave me a 'cortex-m sw device not found' error message (problem persists with the unchanged project as well).
And when I tried the SmartSnippets Toolbox, the software couldn't detect any device
The pictures below are of the device I am using:
I apologize for the bad picture quality; I do not have a good camera. I think the pin connections are all good because before flashing the device, it was running fine.
And the error messages are attached here:
I found this tutorial later on and I fear the problem arised because I did not follow these steps.

Does anyone have any idea what I can do, I am stuck with this at work.
Thank you once again.
