Does anyone yet have a Raspberry Pi Zero 2 W? I'm wondering about the bootup time. With a Raspberry Pi Zero W, systemd-analyze gives me this (39.313s): $ systemd-analyze Startup finished in 4.497s (kernel) + 34.815s (userspace) = 39.313s graphical.target reached after 34.481s in userspace PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

Thank you very much, but really? -- buster 17.585s; bullseye 23.470s. 33% increase. Talk about bloat. |

How often do you reboot? I'm more used to keeping the thing going than boot times, so I like the 5x speedup from the Zero. (I've had a Zero 2 W since the Sooper Sekrit Reseller-only session in early October. Decent machine, and what they've done to stop it getting too hot is pretty marvellous.) |

It's not an issue for me personally (usually--today I've been running something on a pi zero w which requires rebooting when I encounter an error--several dozen reboots today (but that's not why I asked the question)). My question was to find out the extent to which the Pi Zero 2 W might resolve the issue for those who want their MMBasic to be "instant on" like the CMM2. I didn't expect it to reach that speed, but 17 seconds wouldn't seem too intolerable to me (nor, to me, would 23 seconds). |

Here are the figures for both Buster & Bullseye Lite versions (which are the ones recommended for running Pi-cromite MMBasic) Some of Bullseye figures are "strange" to say the least, and note the "graphical.target", I had to double check it was indeed the Lite version. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Buster-Lite armv7l kernel: 5.10.63-v7+ PRETTY_NAME="Raspbian GNU/Linux 10 (buster)" Startup finished in 4.033s (kernel) + 15.376s (userspace) = 19.410s multi-user.target reached after 15.315s in userspace ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Bullseye-Lite armv7l kernel: 5.10.63-v7+ PRETTY_NAME="Raspbian GNU/Linux 11 (bullseye)" Startup finished in 4.089s (kernel) + 21.440s (userspace) = 25.529s graphical.target reached after 16.516s in userspace led PS Pi-cromite runs quite well on both versions although not fully tested! Edit: Peter named his MMBasic port Pi-cromite not Picromite (but I'm a lazy two-fingered typer, like so many others). I've corrected anyway. Edited 2021-11-26 18:27 by led-bloon |

Odd that the "lite" version takes longer than the non-lite. That would be great. Did you test pin control? As I recall, that was the problem the last time I looked--pigpio acting up. |

There is a project to boot a Pi3(!) in less than 2 seconds: https://furkantokac.com/rpi3-fast-boot-less-than-2-seconds/ |

My apologies, the above is an over-simplification of the software performance. I got a command prompt. I ran speedtest.bas ok. From memory, that's about it. The Zero 2 is for the collection, and not for any general use, hence no GPIO pin-headers soldered. I was more directed to the fact that it ran on Bullseye ok. led |
