PROFILE
Chintan Vankar
In July 2025, Chetan Vankar enhanced the flipperdevices/u-boot repository by delivering robust networking boot improvements focused on embedded systems and bootloader development in C. He reworked the CPSW driver probing to use a bind method via UCLASS_ETH, streamlining Ethernet port initialization and improving boot reliability across multiple SoCs. By updating device trees, clocks, and defconfigs, he enabled Ethernet and SPL network boot support for platforms such as j721s2 and j722s. Additionally, he optimized J722s SPL boot performance by enabling CPU caches, reducing boot times and simplifying hardware bring-up for network-enabled deployments. The work demonstrated strong depth in BSP and driver development.

Jul 1, 2025In 2025-07, delivered robust networking boot improvements for U-Boot in flipperdevices/u-boot, focusing on CPSW binding, broad Ethernet boot enablement, and SPL performance optimizations. Key work includes reworking CPSW driver probing to rely on a bind method via UCLASS_ETH and removing explicit probing, improving boot reliability and maintenance. Expanded Ethernet boot support across multiple SoCs/platforms by configuring clocks, CPSW bindings, and defconfigs (j721s2, j722s, j784s4, SK-AM69, AM68 SK, AM62px, AM69 SK-A72). Also implemented J722s SPL boot performance improvements by enabling CPU caches in SPL on the J722s EVM, reducing boot times. These changes reduce time-to-network availability, enhance reliability across a broad hardware matrix, and simplify hardware bring-up for network-enabled deployments.
