OSHPark accepts Kicad board files directly?!?!


I'm working on a small filtering board to filter out high frequency noise from an RC servo power and signal. It's a simple 2-layer board with large traces and large (>= 0603) parts. That means it's within the capabilities of pretty much all online quick turn board fabs.

Wrapped the design last night, time to order the first set of prototype boards.

A few of my favorite quick turn board fabs are jlcpcb and OSHPark. These will be hand assembled, otherwise I'd probably use jlcpcb as they'll assemble boards and have a ton of passives in their catalog of available parts.

All of my ECAD work is done with KiCAD so you can imagine my surprise when I spotted this mention on the OSHPark site of "drag and drop your KiCAD files"?!?!


Looking at their help page it turns out OSHPark will directly accept a KiCAD .kicad_pcb file, no pre-processing necessary.

I'm not sure how long OSH has had this support, maybe its been a while and I just noticed it, but its a huge timer saver over the typical process of:

  • KiCAD plot gerbers (with the correct settings for the board house)
  • Plot drill file (again, with the correct settings)
  • Zip up gerbers and drill file
  • Upload zip file
  • Go through a web based matcher to match files to what they are, front copper, front silk, back copper etc.
These steps take me a handful of minutes (5-10min) but I've also done it a few dozen times in the past year. Uploading the board file directly to the osh site took only a few seconds. The upload worked seamlessly and the preview images looked exactly as expected. I even made a dozen or so minor tweaks and re-uploads as I kept spotting little things in the silk screen that I wanted to correct.

If you use KiCAD and are looking for a quick turn pcb fab I recommend checking osh out. If you aren't comfortable or familiar with the typical upload a zipped gerber file process it could save you an hour or so of effort.

Debugging an imprecise bus access fault on a Cortex-M3

This information may apply to other cortex series processors but is written from practical experience with the Cortex-M3. Imprecise bus access faults are ambiguous, as noted by the term "imprecise". Compared to precise bus errors, imprecise errors are much trickier to debug and especially so without a deep understanding of arm processors and assembly language. Imprecise and precise flags are found in the BusFault status register, a byte in the CFSR (Configurable Fault Status Register). BusFault status register bits The definition for imprecise and precise bits is: [2] IMPRECISERR Imprecise data bus error: 0 = no imprecise data bus error 1 = a data bus error has occurred, but the return address in the stack frame is not related to the instruction that caused the error. When the processor sets this bit to 1, it does not write a fault address to the BFAR. This is an asynchronous fault. Therefore, if it is detected when the priority of the current pr...

Travelling on Spirit airlines out of Boston Logan airport? Here are some tips.

I attended CES 2017 in Las Vegas. Booking the trip late I ended up on Spirit airlines. It was both non-stop, making it six hours to Las Vegas from Boston, and affordable, less than $300 for a one way trip compared to around $700 with JetBlue. Here are some tips that might help you when travelling on Spirit from Boston Logan airport. Eat Spirit is located in the B-terminal, gates B-37 and 38, with its own TSA security checkpoint. While it does have restrooms and places to sit the food selection is limited to a single food stand. I'd recommend eating at the Legal C Bar (number 77 in the image below) prior to going through the terminal security checkpoint. The food and service there were great. Drink The water and other drinks are cheaper if you buy them at the food cart rather than on the flight. Seats The seats on Spirit don't recline. They do this to reduce weight, seat cost, seat maintenance costs, and so seats don't impact the free space of other passengers,...

Yocto recipe SRC_URI for a BitBucket / GitHub ssh git repository

This is a particularly geeky post but because Google searches didn't turn up any information I thought it would be helpful to document the issue and solution for others. I was writing  Yocto recipes that pulled from BitBucket git repositories in ssh form and ran into several issues getting a SRC_URI that worked. GitHub uses the same syntax for their ssh repositories. A BitBucket / GitHub git url, in ssh form, looks like: < username >@bitbucket.org:< account name >/< repository name >.git a more concrete example for a git repository in one of my BitBucket accounts looks like: git@bitbucket.org:cmorgan/somerepository.git Yocto recipes can pull from git repositories by setting the SRC_URI variable appropriately. Unfortunately you can't just do: SRC_URI = "git@bitbucket.org:cmorgan/somerepository.git You'll get errors because the Yocto won't know what kind of url this is. You need to specify the protocol for Yocto to k...
