About you
IRC: lorforlinux Github: Deepak Khatri School: Netaji Subhas Univerity of Technology (NSUT) formely NSIT Country: India Primary language(s): Hindi,English Typical work hours: 9AM - 7PM IST Previous GSoC participation: I participated in GSoC2019 but i was not selected for the project. The project was to make a jekyll website for AIMA organization, Discussion on the project can be found here and the prototype i made can be found here. From the GSoC2019 I learnt the importance of communication.

About your project
Project name: Cape compatibility layer for BeagleBone Black and BeagleBone AI

Description
The idea of this project is to make the same userspace examples work, to use the same references to drivers for peripherals assigned to the same pins between Black and AI. For making the boards pin to pin compatible as in pin names, we are required to create new device tree sources include files. The file "am335x-bone-common-univ.dtsi" defines the pin names for P8 and P9 header of Black and we are required to implement a similar file for am5729 like "am5729-beagleboneai-common-univ.dtsi". To use serial ports and userspace I2Cdev/spidev, aliases provided by the device trees would match. For GPIOs, examples would work using pin names under libgpiod.

The project requires the use of the device tree compiler (dtc) for compiling the device tree source (ex. *.dts, *.dtsi) files. The c programming language will be used for kernel-level programming and gcc compiler along with other build tools will be used for compiling the C source code (*.c).

Experience and approach
I have a good understanding of C, C++, and python. I have done an internship on Embedded Electronics using BeagleBoneBlack. I completed this project called "Mausam national" during my internship. Mausam national is an air quality cum multiple gases ppm level acquisition system. The interesting part of the project is that it can connect to the internet and fetch the air quality data from my university's pollution center that they provide for everyone to use. we used that data for the calibration of the MQ sensors on-board.

I was one of the quarter-finalists in IICDC2017 and during that period I worked with ARM cortex M4 based MSP432. I participated in Electronics Maker contest '17 there I presented a low-cost biopotential amplifier based on TL074 and won Ti's C2000 DSP for the project. I have worked on both hardware and software-based projects, hardware projects can be found on my youtube channel here and software projects can be found on my GitHub here.

Contingency
I believe that if I get stuck on my project and my mentor isn’t around, I will use the resources that are available to me. Some of those information portals are listed below.


 * 1) Derek Molly's beagle bone guide provides all the information needed for getting up and running with my beagle.
 * 2) Content on e-ALE.org is very useful for information that ranges from tutorials and walkthroughs to the level of very advanced stuff.
 * 3) BeagleBone cookbook from Mark A. Yoder & Jason Kridner is the best source for test projects during the prototyping period.
 * 4) The technical reference manuals provided by TI on am3358 and am5729 are the best source for getting the insights on the SoC used in Black and Ai.

Benefit
If successfully completed, what will its impact be on the BeagleBoard.org community? Include quotes from BeagleBoard.org community members who can be found on http://beagleboard.org/discuss and http://bbb.io/gsocchat.

Suggestions
Is there anything else we should have asked you?
