Low memory available, stability problems may occur = bricked board

I've got this error message working on a micro plateform with fastled.h. and lot of pixels to control.

when I got this message, the first upldoad has worked but the next one was impossible!

beware because when you get this error and over a certain limit of free dynamic memory the bootloader is modified and definitively stop to work. the board is bricked for usb upload

I've tried several solutions but without success before to reflash the bootloader with Avr studio and a dragon ICSP programmer.
And I'm sure about the issue because I've do it 3 times.

So be aware! when you get this message if your micro board stop to upload, your bootloader is perhaps bricked.

Sketch uses 8,086 bytes (28%) of program storage space. Maximum is 28,672 bytes.
Global variables use 2,057 bytes (80%) of dynamic memory, leaving 503 bytes for local variables. Maximum is 2,560 bytes.

Low memory available, stability problems may occur = bricked board

Obligatory sp."Low memory available, stability problems may occur == bricked board".
:smiley: Sheesh, some people.

I've seen stability problems in code that only used 73% of available SRAM. Anymore, I don't trust the code if I hit 70% or more.

yes but if you hit compile + upload, it's too late!
it was to go from 80 leds to 400 for test. now I know :smiley:

do you want a video?

If you think it will serve some useful purpose, but personally, no.

AWOL:
Obligatory sp."Low memory available, stability problems may occur == bricked board".
:smiley: Sheesh, some people.

if you are bored when someone report a bug.....

in that case don't make a "compile + upload" button for a code who brick the board!
the strange thing is dynamic memory is the sram. So why the bootloader in flash is corrupted?
we never got something like this with our own bootloader.

in that case don't make a "compile + upload" button for a code who brick the board!

I've no concrete proof any such thing exists (hint)

(Also, I didn't make even a "compile" button, much less a "compile & upload" button)

I didn't say there was no problem, I said I've seen no evidence for a problem.

Or are you telling us you've found the source (another hint there) of the perceived problem?

ok but I found your first answer strange for a global moderator.

I can send my "killer" code to you and you will try it in a micro board.

My first post on this thread was what I like to call a "joke", aka "geek-gag".

Never mind.

ok sorry about that I was not sure on how to understand it :wink:

With my poorly-developed sense of humour, it doesn't necessarily help if you're anglophone.
