During March 2026, Steven Tseng focused on reliability improvements for the chipsalliance/caliptra-mcu-sw repository, addressing a critical endianness bug in McuMbox SRAM memory reads. He resolved data misinterpretation by switching the MemoryReadResponse encoding from big-endian to little-endian, ensuring correct handling of MCU and SOC data during boot streaming. Steven reinforced this fix by developing regression tests that validate system behavior with non-identical SOC images, reducing the risk of flaky failures. His work demonstrated depth in Rust programming, embedded systems, and integration testing, contributing to more robust memory serialization and cross-component data handling within the MCU software stack.
