We are a small company in Virginia designing, manufacturing laptops, desktops, and servers for government and enterprises. Our current product is in the video display sector. The following tasks are to be performed on a Raspberry Pi 4 board running Linux. 1- The MTU on the 1GB Ethernet port of the Raspberry Pi 4 is currently limited to 1500 bytes. Modify the stock system software to create a 9000-byte MTU. 2- The frame buffer on Raspberry Pi 4 is emulated using the on-board GPU. It currently only seems to support 32 bit pixels. Modify the stock system software to support 24 bit pixels (for RGB only, no alpha bits). 3- Modify the stock system software to increase the frame refresh rate to 120Hz from the current 60Hz rate. Deliverables: Provide detailed instructions including source code/script for implementing the 3 items above.

Hello, I see that you are looking for a developer to work on your Raspberry Pi board running Linux and modify the stock system software according to your requirements. I represent a team with extensive experience in working with the Raspberry Pi and Linux environment. We have a proven track record of our skills and I would like to give you some examples of our relevant projects. We created a “Raspberry Pi Video Player”. This is a custom device with specific functionality to download and play video files from a server. Implemented functions: download video files from a server, checking data integrity, VLC player control, VLC optimization for the hardware. The system runs on Raspbian Linux build. We provided custom Linux build and driver development in a variety of projects, for example, in “Happy Code (Custom DIY Tablet Based on Raspberry Pi for Teaching Kids How to Code)”. In the scope of this project, our team created a user-friendly intuitive interactive interface. Also, we built a custom Linux operating system for the tablet and adapted display drivers to be able to work with HD resolution. To create a custom OS for the touchscreen device we modified Debian – the operating system based on Linux kernel. We will be happy to discuss your project with you and help you efficiently. I am looking forward to your answer. Thank you! Kindest regards, Daniel Ternovsky
