It’s been over two weeks since I started on my GSoC project, and what a journey it’s been! Reading thousands of lines of kernel code, prototyping my own drivers and involved discussions with the community members :D

Here is the update :

• Tried out character drivers
• Developed my own sysfs driver with support for both binary and device files.
• Hacked on my mentors driver.
• Got upcalls and down calls working.
• Developed some C + Assembly based firmware for the PRU
• Shared memory implementation between the kernel and PRU.
• currently working on exporting the shared memory to userspace.
