How to open project! about chameleonultra HOT 11 CLOSED

I was able to open and compile the project! I wrote some instructions in my commit!
Did you use the VS-Code Cortex-Debug Extension? What version of GCC did you use? Can you share your openocd commands/files?
How did you compile the bootloader and application in one file or did you upload them seperate?`
Can you share your flashing procedure?

thanks,
Paul

maybe that will help?
(altough unsure if they even use segger studio?)

I'm use vscode + armgcc + openocd to develop.

I will find time later to write the deployment tutorial for the development environment into the markdown, and I have been busy dealing with the production of the chameleon Ultra recently.

Good~~!!!

A、Yes, i'm using cortex-debug extension on vs, and jlink gdb tools(not openocd)

this is content for my launch.json file

{
    "configurations": [
        {
            "cwd": "${workspaceFolder}",
            "executable": "${workspaceRoot}/firmware/objects/bootloader.out",
            "name": "Debug with JLink",
            "request": "launch",
            "type": "cortex-debug",
            "runToEntryPoint": "main",
            "showDevDebugOutput": "none",
            "servertype": "jlink",
            "device": "nrf52",
            "interface": "swd",
            "svdFile": "${workspaceRoot}/firmware/nrf52_sdk/modules/nrfx/mdk/nrf52.svd"
        },
    ]
}

Edit your cortex-debug settings in vs settings.json, to define

    "cortex-debug.armToolchainPath": "Your arm gcc toolchain path",       // such as C:\\UserProgram\\arm_gcc\\none\\bin
    "cortex-debug.JLinkGDBServerPath": "Your jlink gdb executable path",  // such as C:\\Program Files (x86)\\SEGGER\\JLink\\JLinkGDBServerCL.exe

Note: you can replace bootloader.out to application.out to debug app.

B、I'm use armgcc-none to compile firmware for chameleonUltra, download from Official website

Download from Official Website For ARM
and it's version:

C、Use "nrfutil" merge boot and app firmware hex to one file(To install tool from NRF website)

// generate settings page, get a 'settings.hex'
nrfutil settings generate --family NRF52840 --application application.hex --application-version 1 --bootloader-version 1 --bl-settings-version 2 settings.hex
// merge boot and settings page to one file, get a 'bootloader_settings.hex'
mergehex --merge bootloader.hex settings.hex --output bootloader_settings.hex
// merge boot settings and app to one file, get a 'project.hex'
mergehex --merge bootloader_settings.hex application.hex softdevice.hex --output project.hex

Note: You can flash only application firmware to debug, or else the bootlaoder has crc check, your new app from jlink flash will error start and goto bootloader.

D、Flash firmware and Enjoy your dev.

0、Open terminal in projectRoot/firmware/[application ] or [bootloader]
1、Execute cmd make -j4 to compile [application ] or [bootloader]
2、Execute cmd make flash to flash firmware(only one, if your device is new chip, you must to flash soft device!!!)
3、Execute cmd make flash_softdevice to flash softdevice(Optional~~~)
Note: the make flash cmd will auto execute nrfjprog xxx xxxx, If you are interested, you can read the official NRF documentation.

Thanks, I will close this issue when I can get it to run + written instructions!

Where did you get the softdevice.hex file?

Where did you get the softdevice.hex file?

See: {projectRoot}/nrf52_sdk/components/softdevice/s140/hex/s140_nrf52_7.2.0_softdevice.hex

Everything clear and working, if possible please check my instructions for JLink (I have only STLINK)
Instructions in new Pull request #14 !
