Summary
🤩
Rockstar🎓
Top SchoolFredrik Ahlberg is a hardware and firmware engineer with 13 years’ experience, co-founding and leading hardware at Minut from Lund, Sweden. He combines hands-on PCB and firmware development with product-minded leadership, taking prototypes to production across consumer IoT and embedded systems. His open-source contributions to widely used tools like Espressif’s esptool and the Black Magic debugger show deep familiarity with flash/RAM programming, debugging interfaces, and MCU identification for Cortex families. Earlier roles at Ericsson and Axis sharpened his test automation and RF/ASIC verification skills, complementing a formal M.Sc. in Electrical and Electronics Engineering from Lund. Colleagues would describe him as a practical engineer who bridges low-level bootloader details and hardware design while keeping an eye on product reliability and manufacturability.

Nov 2014 - Jul 2020
In-application debugger for ARM Cortex and RISC-V processors.
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:7 commits, 1 PR, 7 comments in 5 years 8 months
Contributions summary:Fredrik primarily focused on adding support for new hardware platforms, specifically the TI TM4C123 Launchpad. They implemented necessary USB CDC-ACM functionality for debugging purposes. Further contributions included reading CPUID to identify core versions and reading CoreSight registers (DEVTYPE and ARCHID) to identify Cortex-M23 and Cortex-M33 debug components. They also made minor code adjustments and comments, enhancing the project's debugging capabilities.
