Default suspicious RAM problems - mvo - 07-30-2003 , 03:50 PM






Hi group,

My company is doubting my applications; there are happening strange things
in the field. It's about terminal running a state-machine on an old H8/500
processor. The problems seems to be weird and like this.

When we write software in the terminal's flash it runs differently from
terminals that have another software-version pre-loaded. In both situations
the previous software has to be overloaded fully (well, thats what is
desired). A lot of people are 'against' us saying the previous version
affects the new version.

A guy made a loading sequence with functions copied to (and running from)
RAM (still don't get how you do that trick, with the source-code in front of
me but whatever). But I want to clear the RAM chip (512K) totally, first.

Any tips on how to check the size of the RAM-chip? (the tricky-part We use
hardware with both 256K and 512K RAM.

Some tips would be appreciated very much!

Best regards,
M/\RK
