Miquèl Raynal
Embedded Linux Engineer at Bootlin
Toulouse, Occitania, France
Summary
👤
Senior🎓
Top SchoolMiquèl Raynal is an Embedded Linux engineer with a decade of hands-on experience designing kernel drivers and platform support for SoCs, currently contributing at Bootlin from Toulouse. He is a recognized Linux kernel NAND/MTD maintainer and active upstream contributor to high-profile projects such as torvalds/linux and u-boot, notably adding SPI-NAND DTR support, OTP handling, and the ->exec_op() interface to modernize raw NAND communication. His work spans bootloader and kernel layers, device-tree and PHY/clock/power domain integrations, and he has upstreamed platform enablement for Marvell Armada and A3700 families. Prior roles include building Yocto-based distributions and low-level drivers for Freescale i.MX platforms, demonstrating strong cross-domain skills from boot to userland tooling. Colleagues value his propensity to refactor legacy subsystems into cleaner, reusable abstractions (e.g., generic ECC engine and MTD partitions rework). He combines formal engineering training from INSA Toulouse and international study at Nanyang Technological University with a pragmatic, upstream-first approach to embedded systems development.

Contributions summary:Miquèl primarily contributed to the Linux kernel source tree, specifically focusing on the MTD (Memory Technology Device) subsystem for NAND flash memory. Their work involved fixing memory leaks, addressing OOB (Out-of-Band) layout issues, and correcting ECC (Error Correction Code) information for various SPI NAND flash chips, especially those from Winbond. The user also added support for DTR (Double Data Rate) operations in the SPI-NAND subsystem, significantly improving read performance, and implemented OTP (One-Time Programmable) support.
