Stack again. Not enough for the main thread. Guess I need to go back to school
to learn about stacks :(
Update on my issues.
msconn crashing was, as suggested, inadequate stack size. Default was 768, and
changing to 2048 and it no longer crashes. This was my first experience of
stack issues with NuttX.
I have now merged the 10.2 release and building and running OK.
Msconn now allows my board to
Yes, I now think so. I know I looked at stack settings but (without benefit of
access to my Linux work machine from home) if I recall they are spread around
the place and I suspect - from other advise here - that it is the app stack
size that is inadequate.
Hopefully a break from it all will ma
Could it simply be a stack overflow?

Hello,
just an idea:
When adding more nested function calls causes a crash, I check stack
overflows.
Sometimes the default stack size specified when defining apps (2048) is
too small, specially you have buffers on this stack, and printf consumes
a lot of stack itself when calling nested for
It is better you create your own blog, some people could like your style to
write the posts!

Hi Tim,
Yes, get a solid settings before moving forward is the best approach.
Thank you very much, have a great Xmas and a Happy New Year!

This is a custom board (SAMA5D27-D5M). I suspect what has happened is
that multiple "messing around" with configs has broken something basic.
To add insult to injury I have messed it all up so badly that the apps
directory won't compile in properly either now.
I will take your advice and retu
Exactly, something is changing the memory layout and forcing the error
to happen.
I can try duplicate it later, but I think it could be specific for
your board configuration. What board/MCU are you using?

Usb_msc_main.c
If I add a "return OK" as the first line of main, msconn runs and returns.
If I put a printf statement before it, I get a crash.
If I do the same in an example app I've written, it is fine.
If I put a breakpoint at the printf statement and step over it, into there it
gets to "vo

Well, here's an odd thing.
I already had FS debug on of course, but not the informational output. Turn
that on, and I can now actually create a FAT volume on /dev/ram0.

Hi Tim,
I don't know the root cause of the issue you are facing, but it could
be some memory misalignment. Try to use GDB to investigate where the
crash is happening.
Also test using other File Systems, if you use USB MSD with FAT then
your host OS will show the content of the SPI Flash.
