Qualcomm Arduino Q - Blink...eventually (When ‘Embedded’ Means Waiting 46 Seconds)

..."the Qualcomm Arduino Q takes at least 43 seconds before the assistant-MCU runs and 46 seconds before user code starts. That delay is due to the Linux kernel + systemd + containers (including App Lab) and other cloud-y tooling stacked on top."

Yes but Linux is free!

@ptorrone That doesn't seem horrible. When I used a Raspberry Pi Zero to make a system to help me photograph a total solar eclipse, I think it took about a minute from power on to running my program. Not great, but I decided not to bother trying to speed up booting Linux since I was going to leave it running for hours so waiting a minute wasn't a big deal.

@jjackowski agree - that works great for that application, boot to running a sketch and other things, looks like the person is explore removing some of the start up.. boot to do something or from low power would be good to keep track of for platforms
