In July 2025, Eric Johnson developed SPI/SPL boot support for the OLinuXino Lime2 s16MB variant in the flipperdevices/u-boot repository. He introduced a new configuration option enabling SPL/SPI boot for boards equipped with SPI flash but lacking eMMC, targeting improved hardware compatibility and deployment flexibility. Eric validated the new boot path through targeted hardware testing on board revision L, ensuring reliable operation for SPI-flash-only configurations. His work leveraged expertise in bootloaders, device tree, and embedded systems, and was implemented in C. The feature addressed customer needs for reduced boot-time risk and expanded boot options in embedded hardware environments.
