Hi all, I am following this discussion with great interest. I am using the PocketBeagle on a musical instrument and it should not take too long to start it up or I miss that all important firsts note!! I am using a PocketBeagle with Linux beaglebone 4.14.108-ti-r127 #1 SMP PREEMPT Wed Jan 29 04:10:14 UTC 2020 armv7l GNU/Linux. I used the console image from e linux.org. I see a few big gaps in the start up as well. Apart from the filesystem mount which takes a long time (in my case 16+ seconds), there is also a huge gap before the PRU comes online (a gap of 28 seconds!!!). I am suspecting the Edimax USB Wifi driver since I see the same even larger gap on my other (standard) image around the startup of that device. Is this normal, is this something to report or does anyone know a solution or direction in which to look?
