Weekly reports

1. All weekly reports will be sent to the mailing list (as that is our primary support venue outside of live chat) on a single thread (to avoid e-mail thrash).
2. They must be sent on Monday to allow for mentors to respond ahead of Wednesdays IRC meeting where all blockers will be discussed live.
3. They must include the following sections:
   • Accomplishments
   • Resolutions to blockers
   • On-going blockers
   • Plans for the next week

Cape Compatibility

The idea of this project is to make

1. The same userspace code work with both BeagleBone Black and BeagleBone AI, using the same references to drivers for peripherals assigned to the same header pins between BBB and BBAI.
2. The same DT overlay work for both BBB and BBAI. For capes, uBoot Cape manager will also be updated to support BBAI so that DT overlays will be automatically loaded during boot.

Milestones

1. Introductory YouTube video.
2. Testing Capes on BBB (Comms, Servo, Load, Realy, Motor, and LCD4).
3. Cleaning up code in beagle-tester and creating new examples.
4. Creating new userspace examples for BBB.
5. Testing new beagle-tester code on BBB.
6. Finalizing BeagleBoard-DeviceTrees/src/arm/am5729-beagleboneai.dts.
7. Testing the BBAI pin control using libgpiod.
8. Testing user space examples with BeagleBone AI.
9. Testing comms cape on BBAI.
10. Testing Servo cape on BBAI.
11. Testing Motor cape on BBAI.
12. Testing Load cape on BBAI.
13. Testing Relay cape on BBAI.
14. Testing LCD4 cape on BBAI.
15. Creating buses DT overlay for BBAI.
16. Testing BBAI u-boot peripheral support.
17. BBAI u-boot SPL cape manager compatibility.
18. Final YouTube video.

PRU Bi-dir bus

TBD

Milestones

1. Introductory Video
2. Setting up BeagleLogic to analyse communication between PRU and Shift Register
3. Configuring the system to use remoteproc and run sample codes on PRU
4. Understanding Writing a character driver
5. Understanding and writing GPIO chip driver
6. Wrtiting code to send simple data to 74hc595.

PRU Improvements

Idea of this project is to implement a compiled language which will compile down to PRU assembly. PRU programming is a uphill task and quite tough for beginners, this language intends to simplify this, by providing a high level language with simple syntax. This will make it easy to get beginners onboard with PRU

Milestones

1. Introductory YouTube video
2. Setting up BeagleBone Black Wireless i.e flashing up to date Linux image and Testing user-led blink code :D
3. Running existing example codes from this repository
4. Implementing int, bool data types
5. Implementing Arithmetic operators
6. Implementing Relational operators
7. Implementing Bitwise operators
8. Implementing Logical operators
9. Implementing Arithmetic operations
10. Implementing Variable assignment
11. Implementing if else elif
12. Implementing for loop
13. Implementing functions
14. Implementing Register access
15. Writing documentation for same
16. Implementing Language backend
17. Implementing Utility functions
18. Testing the language, and implementing example codes.
19. Finalizing and documenting everything done till now, submitting second report for evaluation
20. Solving github issues
21. getting PRUSpeaks to work on the new kernel
22. Writing documentation
23. Packaging the compiler for distribution, like packaging into debian package.

Media IP Streaming

This project aims in porting the existing drivers for the CTAG Face audiocard to the 4.19-rt kernel for Beaglebone AI. Furthermore, the AVB protocol, implementented during a former GSoC Project, should also be ported and optimised to 4.19-rt kernel. More information about the project can be found here.

Milestones

June 8	Introductory YouTube video, review of existing drivers for ctag face audio interface, identifying challenges for porting drivers to Beagle AI and selection of appropriate kernel
June 15	Implementation / porting of ALSA audio drivers for ctag face to Beagle AI --> toolchain setup, driver adoptions, coding
June 22	Port of sound card drivers, testing, performance check
July 3	Finalzing port of ctag face audio card driver to Beagle AI and getting pull request to Beagleboard Mainline
July 10	Review of existing AVB network driver architecture for real-time audio streaming, basis is https://elinux.org/BeagleBoard/GSoC/2017_Projects#Project:_BeagleBone_AVB_Stack , identifying challenges for porting to Beagle AI
July 17	Implementation / porting of ALSA AVB network drivers to Beagle AI --> toolchain setup, driver adoptions
July 24	AVB ALSA drivers implementation for Beagle AI
July 31	Getting ALSA AVB network drivers finished and document everything till now
August 3	Joining AVB ALSA drivers with ctag face audio card drivers
August 10	Performance and integration testing of driver ports
August 17	Completion YouTube video, pull request of driver architecture for mainline
