Can't make flash or make flash_softdevice about chameleonultra HOT 5 CLOSED

Please confirm your device type and connect it to the corresponding debugging probe pin according to your device type.

Note: After erasing all firmware, ChameleinLite needs to use 3.3V power supply for the VCCNRF pin, otherwise it will result in the kernel not having 3.3V power supply and unable to start.

Hold on. I'm using the type-c cable with ultra, do you mean I need some specific cable to flash the device ?

If you are using type-c, Only run usb-dfu can to update your device firmware.

after nrfutil installed, you can run cmd:
nrfutil pkg generate --application application.hex --application-version 1 --hw-version 0 --sd-req 0x100 --key-file ../ChameleonUltra/resource/dfu_key/chameleon.pem chameleon_ultra_app_update.zip
to build update packages.

The above example is to build an update package for an application. If you need to update the bootloader, you need to read the command line documentation for nrutil. I have not tried using USB-SERIAL to update the BOOT firmware yet.

This obviously does not apply to downloading firmware multiple times during debugging (which is too troublesome). If you need to modify the functionality/debugging, I suggest you purchase the JLink probe tool.

Follow your advice, I generated the app_update.zip and enter the dfu mode, use command
nrfutil dfu serial -b 115200 -p /dev/tty.usbmodemEF38944C806E1 -pkg chameleon_ultra_app_update.zip
updated the device.
