[QUESTION] Grand central M4 project

[GMagician]

I'm trying to see what does it mean to implement adafruit grand station M4 into Marlin but I'm lost with a strange error.

AssertionError: Missed J-Link Device ID for malyanM200v2

it's generated when I execute

platformio boards

inside marlin folder where platformio.ini is resident.

From original marlin file I only added:

#

Ardfruit Metro Grand Central M4 (Atmel SAMD51P20A ARM Cortex-M4)

# [env:adafruit_grandcentral_m4] platform = atmelsam framework = arduino board = adafruit_grandcentral_m4 build_flags = ${common.build_flags} lib_deps = ${common.lib_deps} src_filter = ${common.default_src_filter} +<src/HAL/HAL_GRANDCENTRAL_M4>

this is error I get: errlog.txt

I see from closed issues that this error has been already noticed by other guys but no solution has been given

pip install -U platformio command platformio upgrade platformio update

have been executed but don't solve it

platformio.ini.txt

Note: It will be impossible to me to answer till next week

Where did you get malyanM200v2 board? I don't see this board in our registry.

[GMagician]

Where did you get malyanM200v2 board? I don't see this board in our registry.

This is what I get when I launch "platformio boards" it should only return supported boards, but I get reported error

Edit: I don't really know which board is malyan and where does it come from

[ivankravets]

Which source code do you use? Where did you get it?

[GMagician]

Marlin source code? or platformio code? I don't use platformio source, I downloaded from web site the window compiled version

Edit: Core version since I use VS community edition to edit project

[ivankravets]

Do you use the latest version of Marlin firmware?

• https://github.com/MarlinFirmware/Marlin/tree/bugfix-2.0.x

I don't see this board. https://github.com/MarlinFirmware/Marlin/search?q=malyanM200v2&unscoped_q=malyanM200v2

[GMagician]

Yes I just redone everything again yesterday night. Downloaded marlin 2.0.x, "update" and "upgrade" platformio and "platformio boards" and got same error. But since "boards" should report platformio supported boards...how Marlin code may be involved?

Edit: And Yes, Marlin doesn't support such board!

[ivankravets]

It seems that you installed another dev/platform with a broken board manifest. Please remove ~/.platformio folder and restart VSCode.

[ivankravets]

You can check dev/platforms via pio platform list or visiting ~/.platformio/platforms. The broken malyanM200v2.json is located in boards folder of one of dev/platform.

[GMagician]

I'll try but I don't know how I could downloaded that...never done anything else than "platformio update" "platformio upgrade" and compile via VS (not vscode)

[GMagician]

Thanks for support

[GMagician]

I think there something else, here is "pio platform list" report: log.txt

and C:\Users[username].platformio\platforms contains only avr & saml folders

[GMagician]

Text search inside files gives no result, Get-ChildItem -r -Filter "malyan*" starting from same folder report no file

[GMagician]

deleted saml folder and it works... I executed: pio init --ide visualstudio --board adafruit_grandcentral_m4 and now I get the error again

[GMagician]

next test: deleted files and subfolder inside saml folder now I only have platform.json platform.py and I still get the same error. error disappears only when I delete attached platform.json platform.json.txt

[ivankravets]

Where did you get saml folder?

[GMagician]

it is created by: pio init --ide visualstudio --board adafruit_grandcentral_m4 that downloads all tool chain

[GMagician]

real folder name is atmelsam

[GMagician]

Found! Such board is define inside Marlin folders!

[ivankravets]

Could you show me here https://github.com/MarlinFirmware/Marlin?

[GMagician]

Of course I can, it's here: https://github.com/MarlinFirmware/Marlin/tree/bugfix-2.0.x/buildroot/share/PlatformIO/boards since I don't know how PlatformIO works nor I know Phyton language it has been an adventure to discover where the issue was. I already open an issue in Marlin repository about that https://github.com/MarlinFirmware/Marlin/issues/14054 and guy that added board wrote:

PIO should get proper json definitions for the M200/M300 series soon, since ST’s core now officially supports them.
