How long does the bootup take? Shut down? Do I have to tell it I'm about to shut down or does just turning off the car do fine? Are there any other issues related to this that I should (would want to) know about? Thanks-

How long does the bootup take?

From a full power-down (i.e., power completely removed), about ten seconds on my Mark 1. Probably similar on the Mark 2.

From standby mode, about 0.000000 seconds.


Shut down?

Exactly 0.000000 seconds.


Do I have to tell it I'm about to shut down or does just turning off the car do fine? Are there any other issues related to this that I should (would want to) know about?

No, just turning off the car, or even yanking it out of the dash while it's playing is just fine. It doesn't need to be told to shut down. Although, if you want, you can manually put it into standby mode.

It's designed to shut itself down gracefully when it loses power, so there's no issues related to that. It only needs a couple milliseconds to save its current state to NVRAM, which it does when you shut it down or when it detects it's had the power removed. Sort of as a "last dying act", if you will.

The Mk.2 boots faster than the Mk.1 - and a car boot is a lot faster than a home boot. 10 seconds should be about the worst case, best case is (I think) about 7 seconds.

Not bad, considering we bring unix up and boot a sizeable application in the same time (or faster) that a lot of CD autochangers take to notice the disc that was already loaded!

What causes the difference between home and car boot?

In the car you can assume certain things, such as a second hard drive won't have been fitted since the last sync. Not having to time out waiting for a non existant second disk saves quite a lot of time for single drive players. There are other time savings as well, but Hugo knows the details better than I do.

Actually, the second disk probe skipping isn't implemented yet, but it's on my todo list.

The main things which make it boot faster is that it doesn't wait to be upgraded, so there's no pause for ~1 second at power on, and no pause for ~1 second in the pump program. Saves a couple of seconds. The mk1 did fast boots too, though not the very very first units.

Is this boot-up tweaking in hardware / are not all 300 Mk1s equal?

No, some had later initial-boot firmware than others. This can be upgraded, but you need to open the unit, fit a link, then upgrade with your fingers crossed - if the upgrade fails, your unit is toast (which is why you have to do the link thing). Older units still skip the pump stage, but take maybe 1s longer to boot in the car than newer mk1's.

Hmm, now the issue. Does Tony buy a Mark 2 now that this information is revealed?

In reply to:

if the upgrade fails, your unit is toast


Main Entry: toast
Function: noun
Date: 15th century
a : sliced bread browned on both sides by heat b : food prepared with toasted bread


Which would explain why the upgrade failed in the first place

I'm sorry... it's just turning out to be one of those days...
