Hello everyone,
I have developed a program that utilizes UART communication, Bluetooth Mesh, and TWI/I²C functionalities, all within the framework of the Zephyr project.
The program runs flawlessly on an nRF52832 Development Kit, where I am able to receive log outputs correctly and process UART inputs. The build configuration for the nRF52832 DK has worked as expected.
I encounter a problem when attempting to run the same program on an nRF52840 Dongle. After adjusting the corresponding build configuration for the nRF52840 Dongle, I experience the device crashing and not even shows a COM port. Is it possible to obtain an output or diagnosis of my error without relying on the COM port?
I'm uncertain whether this issue stems from hardware, software, or compatibility problems. Has anyone encountered similar issues or can offer assistance in troubleshooting?
To provide some context, I utilize Visual Studio Code with the nRF Connect plugin for both developing and programming the nRF52832 DK. Additionally, I use the nRF Connect Programmer for flashing the nRF52840 Dongle.
