Daily progress :

Date : 31 May 2019

  • First I made an introductory youtube video of my project
  • Purchased hardware related to this project like 8-bit logic analyzer ,logic level converter
  • Understand about the code structure on making kernel module Beagleboard and understanding the beaglelogic code docs
  • Read a little bit about kernel module development from this page .

Date : 1 June 2019

  • Till now made the circuit based on the GitHub link withh shift register circuit diagram.
  • Made the circuit for testing the board see the circuit drive link
  • Further work is to implement first user space program then PRU assembly code program.
  • completed studing kernel module developnment from site as suggested by my mentor and further looking into makefile

Date : 2 June 2019

I think i should also include blocker and goals in my further work

  • Till Now
    • Today I studied more about kernel module development and try to understand the code base starting from docs, then kernel folder and firmware folder
    • Try to complete the first week commitment of making the video for the different interfacing circuit but faces some problem due to less understanding assembly code in PRU
    • As i was working earlier in the User space so i was comfortable to make the program their but i want to submit the video and code with the assembly code
  • Blockers:
    • During navigating through the code of beaglelogic .asm file are less understandable for me .
    • Less understaning of the PRU assembly code to tackle that i watched again pru video from beagle bone site.
    • came across a github page during my search for barebone pru programming on pocket_beagle_samples
    • And downloaded the Sitara PRU but it was too big to be understable to me.
