During January 2025, Peter Lin contributed to the flipperdevices/u-boot repository by enabling OP-TEE support on RISC-V platforms, focusing on both security and performance improvements. He introduced a configurable load address for OP-TEE and integrated OS image loading via binman, enhancing deployment flexibility and reliability. Peter also set the default cache line size to 64 bytes in Kconfig, improving memory alignment and performance for RVA23U64 profiles. His work leveraged skills in Device Tree, Embedded Systems, and Kernel Configuration, using C, DTS, and Kconfig to deliver well-documented, maintainable features that addressed deployment and compatibility needs without reported bugs.
