Take the following with a grain of salt in that it's probably outdated, but it may also be something to consider if you're not planning on using capes: A few year's back on BBB, we ran across an issue where config-pin gave an error when attempting to reconfigure pins that were already in use by

We had a similar issue on the BB-X15 (am57xx) a few year's back, where the primary image (SPL, u-boot, kernel, debian) was flashed to eMMC. We were using an SD card for logging, and the SD card was formatted as FAT to allow reading from Windows. However, an improperly formatted SD card

Hi when you say you're collecting information for faster boot times, can you tell us more about what OS and FS you're running? Why are you focusing solely on speeding up the hardware as opposed to ways to make u-boot and the kernel to boot faster, for instance? Here's a prior post on speeding

Hi Steve, I'm just picking back up Linux on the BB-X15, and was looking for expansion headers. Saw a couple of designs online (someone had gerber files available for one design, downloadable online). These were developed by a hardware engineer on our team to support our custom board port.

Hi Steve, Now, I'm in the same boat. These were developed by a hardware engineer on our team to support our custom board port. We really wanted to send this to BB.org after all the help they gave us. But as noted above, the hirose connector was flipped, so we weren't able to expose the 30

Thanks for cross referencing all the docs Mark! I'm sorry I missed this, but I stumbled upon an older GSOC project, libdsp-x15, which looks like it adds an FFT, IFFT, and biquad/sos functionality which are callable from a library added to Linux. Not sure if that's part of OpenCL..
