KB and DJ are BACK and kick the show off with the biggest news in the lacrosse world: Paul Rabil announced his retirement from playing our beautiful game. The guys discuss his impact on the sport, their sadness of no longer seeing him play moving forward, but also their excitement for what the PLL is going to grow into now that Paul can fully dedicate his time to growing the business side of the game. Then the guys get into their 2021 PLL Championship Game preview with some help from an old friend and some new ones. Kyle Jackson kicks off our guest list (18:50-55:34) as he gives insight on what it takes to win a championship, the experience this Chaos roster has in title games that nobody's talking about, and of course we talk about his incredibly adorable daughter who has become the face of Chaos LC. Then the guys are joined by Ian MacKay (1:13:27-1:52:51) and you know we had to bring up the "Connor Fields trade", how Ian has transitioned to the SSDM position, the pre-championship anxiousness, and what his expectations are heading into D.C. as his squad takes on the two-time defending champs. Then our mini media day wraps up with the "Trash Man" Jay Carlson (2:06:53-2:30:47) and Jay gives KB his thoughts on playing in a third straight championship game, playing for a title so close to home, if Whipsnakes will be a legacy/dynasty if they pull off the win, playing with Zed Williams, and so much more. GO BIG OR GO HOME! We'll see you all in Washington, D.C.  Follow Us!

OTB Episode 187: Paul Rabil Announces His Retirement & 2021 PLL Championship Preview With Kyle Jackson, Ian MacKay, & Jay Carlson

Welcome Jay Carlson!  The new article “So you want to build an embedded Linux system” is 35,000 words. Why not a book? Friend of the show Drew Fustini was on embedded last week talking about building Linux Jason and Robert from BeagleBoard.org on TAH “I’m your classic electrical engineer” For the aforementioned article, Jay designed 10 boards with different application microprocessors. Took 3 hours on the software side Tweeted about baremetal vs linux  https://twitter.com/jaydcarlson/status/1313730320169078784  Device tree Operating system Object files in C POSIX A33 UBoot, Yocto, Buildroot Building for the A33 Git repo Olinuxino A33 board Erik Larson on the Contextual Electronics Podcast Want a good exercise for learning the build system? Change where the UART is located What if they don’t know linux? “I just break stuff and cycle around and keep trying” Twitter thread about linux shell commands V3S Allwinner Hackaday podcast talked about the 0.8mm pitch parts Using higher grade parts to get more margin on (memory) parts $50 bucks and a weekend “Just try it” 10 breakout board with parallel board Adding a new driver NUC980 internal RAM Student stories Spotify daemon Networking is “free” SDIO wifi module for $0.60 Set top box example   Jay and Chris discuss a theoretical project, like a sous vide with a cap touch screen How big is the screen? With most of the 10 boards shown, they’d be OK up to 5″ Newer displays have MIPI Most parts are older and have parallel interfaces (which can be an EMI risk) MP1 and A33 only have MIPI LVDS Video of the QT5 demo iMX8 is another category of layout Robert Ferenec course NUC Research lab at Univ Neb – Lincoln Occult tracking of pigs When do you switch down to a micro? STM32F7 Power considerations $1 microcontroller article When should you use an RTOS? For most programs running on Linux, Jay recommends to wrap it in a while 1 loop. “Linux benefits from the whole human race” Combining low power and high power systems. Sometimes Jay will send data over USB (if he needs high speed transfer) or set up SPI/I2C for direct control. MP1 and AM335x have built in micros Listener questions! “Have any vendors contacted him to use his designs as a devkit or just permission to promote it? He mentioned working with one on GitHub for bug fixes but I think that was it.”  Ran a verison without serpentine traces Overclocking the memory chip to try and break it Vendors should use a 0.1″ form factor   “What CAD package did he use for all of those boards?”  Altium   What core elements does he try to address in the class, and as embedded systems change where does he see intro course work going?  Intro embedded systems class Working on a platform to learn embedded systems Jay talked extensively about engineering education on Embedded.fm episode 303   Which of the three pinmux tools (NXP, TI or ST) did Jay like the most?  All similar   Assume I now working hardware (an iMX6ULL series board) as a base I can work upon. After what complexity point should I consider using this embedded linux system in a project? Any luck interfacing with current smartphones cameras?  Camera modules will be raw output over MIPI   Do you see embedded linux, combined with something like etherCat or modbusTCP, as a viable replacement for PLC machines?  This is the type of application the AM335x is targeted at   How much did he use the dev board from each part before making its own board ?  Not much. Most went straight to proto. THe STM32MP1 dev board stinks as a SBC.   Hard RealTime Linux for safety applications. Why is it a good idea and why it’s a horrible idea? How good are different silicon vendors about upstreaming their kernel patches?  What is upstreaming? Smart cameras and rear cameras example Quectel module with Android   Why Lincoln, Nebraska? Yes Man Jay now works for Virtual Incision, a surgical robot company located in Lincoln.  You can find Jay via his website JayCarlson.net. You can also find him on twitter at @jaydcarlson.
