Hello,
I was hoping to hear your opinion about a serious problem I have - it is either I solve it or reduce my LPC2478 CPU speed from 72[MHz] to 64[MHz] (11% loss. The problem does not seem to be occurring at lower MHz settings). I posted about this in the past but it was a long time ago. When I place a controller in an environmental chamber and increase the temperature to 80+ Celsius degrees, I often see data abort exceptions, and sometimes I get the impression that the PC takes a hike (even the firmware LED that blinks every 1 second becomes irregular for a while before it stops). The program is launched by a boot loader and has a lower level supporting firmware layer that handles some interrupts (not all). I also see that if RTX is not started at all (but the application hangs in a "for (;;)" loop instead, hence the bootloader and firmware layer were/are involved, but the application is idle) - the system never crashes! I have excluded, as far as I could tell, the roll of external memory or RTX in this situation. However, I still suspect RTX a little (even though my test programs never crashed). My question: did you ever encounter such a situation? Where do I look best? can this be the result of a misbehaving peripheral? NXP have confirmed the LPC2478 is not the reason.
"(I have a new, interesting post)"
Where?
There's a new post, but surely interesting is not a true description?
Or was that an attempt at irony?
Not knowing your true name, I must wonder: have you ever posted something useful on this (or any other) forum? please stop hijacking my thread. I'm trying to be informative (=helpful). if you are in a mood for child's play, I suggest you go to a kindergarten.
Is that you being serious again?
Have you tried looking for the Keil command line option -SetMaxTemp=80
You'll not find it. It's not a Keil related problem.
this really is beyond you, ha? this is an issue that might effect Keil USERS and the safety of their product since Keil supports the LPC2478, thus very much their concern. Apart from that, I don't remember asking you when, if or what I may or may not post. Just go away, it won't help you.
Ok.
You're obviously happy with your tenuous links.
