Developed SPI/SPL boot support for the OLinuXino Lime2 s16MB variant in the flipperdevices/u-boot repository, focusing on embedded systems and bootloader configuration. The work introduced a new configuration option enabling SPL/SPI boot for hardware setups using SPI flash without eMMC, specifically targeting board revision L. Using C and device tree expertise, the developer implemented and validated the new boot path through targeted hardware testing, ensuring reliable operation for SPI-flash-only deployments. This enhancement expanded boot options, improved hardware compatibility, and reduced boot-time risk for customers relying on SPI/SPL boot paths, reflecting a focused approach to embedded system reliability and flexibility.
