In application debugger for ARM Cortex microcontrollers.
Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:8 commits, 10 PRs, 16 comments in 4 years 6 months
Contributions summary:Mark primarily contributed to adding and updating support for Nordic nRF51 and nRF52 series microcontrollers within the blackmagic debugger. This involved identifying device IDs, updating device definitions, and implementing support for features like mass erasing when APPROTECT is set. They also added code to utilize an external script to gather device IDs and incorporated external resources like openocd to improve the accuracy of device information.

Wear-leveled SPI flash file system for embedded devices
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:6 commits, 1 PR, 1 comment in 3 days
Contributions summary:Mark primarily contributed to the implementation of a Python binding for the SPIFFS file system, a wear-leveled file system designed for embedded devices. They developed a Python interface, integrating with C code to allow the SPIFFS file system to be used within Python environments. The user also focused on fixing issues and improving error handling within the Python binding, ensuring the software's robustness. Additionally, the user created tests to validate read, write, and erase functionality of the file system at a block level.
