In my spare time, I was doing some OpenBMC Yocto builds on my Linux machines, and decided I wanted to copy these files over to my Windows PC. Little did I know how complicated this could be.
In Episode 2 of the Basys Chronicles, I configured (programmed) the Artix-7 FPGA with a simple Binary-to-Decimal calculator application, through the USB-JTAG port. But, power down the Basys 3, and it goes back to the Built-In Self Test that comes with the board. This week, I flashed the calculator configuration into the nonvolatile SPI flash, making it the default boot-up configuration.
In the Basys Chronicles Episode 1, I started to learn about FPGA programming using Xilinx’s Vivado tool and the Digilent Basys 3 Trainer Board. Now, after a few weeks (okay, time flies; it’s been almost two months), I’ve made some good headway in understanding FPGA architecture and creating some interesting designs that do useful things.
Over the last two and a half years, I've intermittently chronicled my explorations into some fairly esoteric technical topics, using the MinnowBoard Turbot board as a platform. And yes, time flies, and I've covered a lot of ground. All 45 chapters are listed below. Enjoy!
This past week, I attended the AUTOTESTCON 2019 conference, the premiere Defense Automated Test Equipment show, that has the theme of “increased mission effectiveness through advanced test and support technology”. As you may have seen, I was honored with the “Walter E. Peterson Best Paper on New Technology” award for Mitigating JTAG as an Attack Surface (note: it might take a little while for the paper to be posted on IEEE Xplore; you might have to check back later).
