Worked on the flipperdevices/u-boot repository to introduce Essential System Management (ESM) support for PMICs across k3-am69-r5-evm and j784s4_evm_r5 platforms. The work involved adding a PMIC ESM node to the Device Tree using DTS and enabling ESM-related configurations to support system resets and ESM programming during boot. This approach improved system stability and error handling at boot time for embedded systems. Leveraging skills in configuration management, device drivers, and embedded C, the developer focused on robust boot-time configuration, ensuring that ESM features are reliably initialized and managed across multiple evaluation platforms without addressing bug fixes.
