How do you mean that ? You mean you got blue screen with some dumped codes on LCD ? :smile:


Bad source coding.
Bad and defected uC.
Bad circuit, and bad power supply.

Hello!

Your question is not accurate enough. What happens?
Do you have a "crashing" application? On what processor?
What do you mean by crashing? Does it loop forever?
What do you mean by "from a working system"? You had an
application, you changed something and it "crashes"?

Hello!

If I tell you : My TV used to work, and it does not work well and sometimes does not work at all,
can you conclude anything about what is wrong?

- What processor?
- What board ?
- What compiler?
- What program (or at least publish the part of the program where the bug happens).

If you don't tell us the above strict minimal information, I guess nobody can help you.

Dora.
