Corrected date 'Wed, 29 Oct 2025' should be 'Tue, 29 Oct 2024' as October 29, 2025 falls on a Wednesday but this appears to be a typo for a past date (2024).

Direct modification of CFLAGS/CXXFLAGS using += can cause issues in BitBake. Use the _append operator instead: CXXFLAGS_append = \" -fPIC\" and CFLAGS_append = \" -fPIC\" to ensure proper flag concatenation.

There was a problem hiding this comment.
TODO comment indicates license verification is incomplete. This should be resolved before merging to production, especially for a proprietary license.

The date 'Wed, 29 Oct 2025' is in the future and incorrect. October 29, 2025 is a Wednesday, but this appears to be authored in 2024 or earlier. Update to the correct historical date when this patch was created.

| # TODO: Verify license -- it is Silabs specific | |||
There was a problem hiding this comment.
The TODO comment in line 1 indicates the license needs verification for Silabs, but the LICENSE field is set to 'Proprietary'. This should be clarified - either remove the TODO if the license is correct, or keep investigating if it's truly proprietary vs. a specific Silabs license.

There was a problem hiding this comment.
The LICENSE is set to 'Proprietary' but the checksum points to a specific license file. If the Gecko SDK has a specific license type (e.g., Zlib as is common for Silabs SDK), the LICENSE field should reflect that rather than 'Proprietary'.

Inconsistent whitespace usage before closing parameter: line 8 uses empty string '' while line 9 uses single space ' '. For consistency and clarity, both should use the same convention (preferably empty string).
