@xenic
I know this crashes from my AOne XE.
I fixed it after MUCH hassle and trial and error by reducing the size of the RAM to 512MB (read 1 Module). As soon as two modules were in OR a 1 GB stick it kept crashing on me.
Unfortunately it seems that you already tried that.
I donŽt know what it could cause in your case, but iŽll be interested in a solution youŽll eventually find (maybe there *is* a bug afterall?)
Good luck

(SAM-flex)
Sucks in my opinion. Seems like an admission that the 800MZ board is flawed and had to be slowed down.
Maybe is not a 'sucking' problem, but a bad timer chip! Afterall, isn't it a SAM 667 overclocked?
[ b] I've been compiling programs with OS4 for a couple of years and never encountered problems as serious as this. [/b]
What does ACube think?

@xenic
What's your point?
Send it back to ACube! You're wasting your time trying to compile your code if there's a hardware timing problem. Let them look and see. It's under warranty, yes? Other SAM owners haven't been as annoyed as as much as you, so let's re-evaluate the problem and ask ACube to checkout your board. I would do this if I was in your predicament.

@all
the ppl with the sam 600mhz have this kind of problems too or it is just for the overclocked version ?
I am plan to use one sam and this kind of topics make me worried.
I never use the AmigaOS 4+, it have a guru meditation like the classic ?
how it show the crash ? some report ?
do you know if it is a really a stack overflow to just increase the stack to try abort the problem ?
BR,
edit ************
looking the 440ep architeture maybe the problem that we are having, and looking we giving much stack to the environment, I suspect the problem is in the memory alocation.
The PPC 440ep have a bug in the last 256k alocation anddress, if the OS no make it unvailable, I do not know if it is, we will have problems if the program tray get this .
from the errata
-------------------------------
CHIP_11: End of memory range area restricted access.
Category: 3
Overview:
The PPC440EP DDR controller acknowledges transactions which cross over the end-of-memory-range boundary and correctly responds only with the valid data. When the PLB3-to-PLB4 bridge is the PLB4 bus master making the read request to the DDR controller, it waits indefinitely until it receives all of the data requested regardless of the boundary condition.
Impact:
Since the DDR controller only returns the valid portion of a read request, the PLB3-to-PLB4 bridge waits indefinitely for the remaining data preventing other PLB masters from completing their transactions.
Workaround:
Forbid any application to access the last 256 bytes of DDR memory. For example, make your operating system believe that the last 256 bytes of DDR memory are absent.
---------------------------
Maybe other problem, but maybe is in it.
no much data about what you are dooing to know more about the problem.
sorry to not explain best, my english is terrible.
I hope it help you.
BR
Ice
