Tested this on my hardware and the HWID needs to be adjusted to be 0x2890 0x8022, I think the zero was a typo. Specifying the COM port directly will skip that check and will let it keep working, though

Correction, this needs to have BOTH HWID's, not changing the singular one. The bootloader, which can sometimes get stuck searching for an upload, uses the HWID you used. There are cases where PIO will get stuck and not be able to find the COM port when that happens, so both will be needed.

You don't need this line because the code below it that checks for "is there a build.variant and if yes add it to the cpp path" already takes care of this:

platform-atmelsam/builder/frameworks/arduino/arduino-samd.py

Lines 214 to 221 in 1718730

if "build.variant" in board:
variants_dir = os.path.join(
"$PROJECT_DIR", board.get("build.variants_dir")) if board.get(
"build.variants_dir", "") else os.path.join(FRAMEWORK_DIR, "variants")
env.Append(
CPPPATH=[os.path.join(variants_dir, board.get("build.variant"))]

Just to be clear, the only line I don't need is 191? Or also the two first arduino lines?

so, this would be the result:

CPPPATH=[
    os.path.join(FRAMEWORK_DIR, "cores", "arduino", "api"),
    os.path.join(FRAMEWORK_DIR, "cores", "arduino"),
    os.path.join(FRAMEWORK_DIR, "Teknic", "LwIP", "LwIP", "port", "include"),
    os.path.join(FRAMEWORK_DIR, "Teknic", "LwIP", "LwIP", "src", "include"),
    os.path.join(FRAMEWORK_DIR, "Teknic", "libClearCore", "inc")
],

Correct, only os.path.join(FRAMEWORK_DIR, "variants", "clearcore"), is not needed.

os.path.join(FRAMEWORK_DIR, "Teknic", "LwIP", "LwIP", "port", "include"),
os.path.join(FRAMEWORK_DIR, "Teknic", "LwIP", "LwIP", "src", "include"),
os.path.join(FRAMEWORK_DIR, "Teknic", "libClearCore", "inc")
],

LIBPATH=[
os.path.join(FRAMEWORK_DIR, "Teknic", "libClearCore", "Release"),
os.path.join(FRAMEWORK_DIR, "Teknic", "LwIP", "Release")
],

LIBS=[
"ClearCore",
"LwIP"
