Project for Duc D. - Help Build a Star Tracker

We're a team of MIT graduate students working on building and open-sourcing a star tracker (a piece of satellite hardware that performs celestial navigation). We need an experienced Zynq developer to help build the image processing pipeline. We've already built the board: Photo: [login to view URL] Layout: [login to view URL] Hardware: Zynq 7010 clg225: [login to view URL] Python 1300 monochrome imager: [login to view URL] 128 Mb QSPI Flash: [login to view URL] 8 GB microSD Card There are two challenges with our board: 1. No RAM - Our board does not have a DDR memory chip. The design can only use L2 cache and the QSPI Flash. For example: http://www.wiki.xilinx.com/Zynq-7000+AP+SoC+Boot+-+Booting+and+Running+Without+External+Memory+Tech+Tip 2. No SD card booting - The Zynq 7010 clg225 cannot boot directly from the SD card, the FSBL needs to be in the QSPI Flash. This project can be broken up into milestones: 1. Boot from QSPI Flash, blink one of the LEDs, and send "Hello World" over UART. 2. After booting, take a picture every second and save them on the microSD card. 3. Subtract from the image its median-filtered version in the PL (output = image - median_filter(image)), find the 10 brightest pixels in the PS and send them over UART. Code should be written in Vivado Design Suite (WebPack version) and should be well-commented.
