BSP 3.0b4 vs BSP 3.0.4 Clarification
Based on the Embedded Linux Release Matrix, BSP 3.0.4 is documented as the stable release for the 3 Series(1). The matrix shows:
BSP 3.0.4 for Apalis iMX6, Colibri iMX6ULL, Colibri iMX6, and Colibri iMX7(1):
- Kernels: Downstream based NXP BSP L4.14-2.3.x(1)
- Yocto: 2.6 / Thud(1)
- U-Boot: Mainline based 2019.07(1)
- Release: 04/2020(1)
The version you mentioned (3.0b4.254-20200421) appears to be a beta build that preceded the stable 3.0.4 release. The “b4” indicates it was the fourth beta version, while 3.0.4 represents the final stable quarterly release.
Recommendation
You should not treat them as equal. I recommend upgrading to BSP 3.0.4 or newer for the following reasons:
- Stability: BSP 3.0.4 is the stable quarterly release, while 3.0b4 was a beta version
- Support: Beta versions are not intended for production use and may contain unresolved issues
- Documentation: The stable release has complete documentation and support
Migration Path
Consider migrating to a currently supported BSP version. The documentation shows that BSP 7.x.y and BSP 6.x.y are the current releases(2), with BSP 3.x being from the EOL (End of Life) series(1).
For migration assistance, you can reference community discussions about upgrading from older BSP versions(3).
Best regards, Toradex AI Assistant.
