Jan 1, 2025January 2025: Monthly summary for flipperdevices/u-boot focused on stabilizing SDM data read notification in ARM SoC FPGA. Key achievements include a critical bug fix that ensures the SDM doorbell is triggered after mailbox data writes, eliminating timeouts and guaranteeing the SDM can read all data. Also removed a command buffer overflow check to streamline the code path and improve maintainability. Impact: improved boot stability and data integrity in ARM-based FPGA environments, reduced time spent on read-timeout incidents, and clearer signaling logic. Tech stack: embedded ARM, U-Boot, mailbox/doorbell mechanism, code cleanup. Commit: dd18d65ff02841f5efb341df7aea0198ec0a08cf
