I'd start by cleaning up the code you posted, like giving the pins sensible names instead of just numbers, then maybe work through some of the programming examples.

I'm pretty sure there are plenty of examples for the SR04 - have you tried the Playground?

Modified bootloader, carefully crafted to avoid using RAM that the user sketch would have used.

Hardly seems worth the effort - simpler to avoid the bugs and the crash in the first place.

(And yes, I do use crash dumps, but the devices have multi-core processors, hundreds of MB of RAM and tens of GB of flash, so not only is there spare capacity to get the dumps out, but there's also more fingers in the pie to put the bugs in in the first place)

There are approaches to this - for instance if the crash causes a reset you can have
a switch on a pin that is sensed early in setup() - if the switch is active run the sketch,
if the switch isn't active, run a RAM dump and then wait.
Run a RAM dump on memory that has probably just been reintialised by crt0?
No, not a good idea..
"setup" is far too late.

Looks pretty self-explanatory to me.

test.ino:42:29: error: 'gt' was not declared in this scope
Code:
if (mySerial.available() &gt; 0)

Code:
if (mySerial.available() > 0)
perhaps?

smiley-confuse.pF, I mean and you understand well...

I do understand well - I work on devices where frequencies are specified from mHz to GHz.
It's really important to know where your shift-key is.

I'm pretty sure you can't buy petaFarad devices.

Are they really "underwater" units, or simply "water-resistant", like automotive parking sonar sensors?

This is a rather different situation than that with the transistor
If the AVR's output stage isn't a transistor, what is it?
And if it is a transistor, how is the situation different?

I think we've already established the WProgram.h is not the correct approach.
57  Using Arduino / Programming Questions / Re: i have problem with this arduino coding..im lost... help me please!!!! on: September 14, 2014, 02:08:29 pm
theres no italic when at arduino softwre..
it goes italic when i paste here only..
It goes italic when you incorrectly paste it here.

Which version of the IDE are you using?
58  Using Arduino / Programming Questions / Re: i have problem with this arduino coding..im lost... help me please!!!! on: September 14, 2014, 02:04:47 pm
And what does it look like without italics?

You've still got WConstant.h

Now try posting the code without smilies and italics.
