Re: H300 bootloader - another (final?) push

Hi pondlife,

I REALLY welcome your effort to finally create a new (release) H300 bootloader!

> The current released H300 bootloader (v5) is now over 3 years old, and has

I don't care about this - I nearly never use my (non-LCD) remote anymore.

> - USB fails to work at all (on some devices)
Never had problems - neither with release nor with SVN versions.

> - Lacks RTC alarm support (* also needs FS#7814)
Would be nice - but is not important for me

> - Loud audio thump at startup
Never noticed this.

> - Hard disk click entering USB (on some devices)
Sometimes I have this...

What does "Shut off backlight properly in USB mode" mean?
That one sounds important to me

> Personally, I'm successfully running a bootloader I built,
I currently still run the unmodified v5 bootloader on my stock H340.
Actually I've to say I returned to it again - after I had some draining issues
with a SVN version.
I reported this as comment at FS#4753 - as you already saw (but I missed your
comment - sorry).
I'll now have a deeper look at it and try to find out what causes the
different behaviour.

So could LinusN tell us the revision so that we're able to have a look at the
differences to the previous version?
And what happens if some of us bricks his device?
Is it worth the effort to send it to LinusN to unbrick it?

I'm absolutely willing to help and bring this to a reasonable "end".
Though my spare time for coding or even for analysis is very limited.
But I'll do my best...

It's absolutely reasonable!
I think we should also have a (re)look at several flyspray patches regarding
the bootloader code, noticeably FS#3039 and FS#9202
and also have a deeper look at some feature requests e.g. in FS#5504 or FS#8085.

kind regards,
Matthias (aka Massa)
