I have 2 TS7500 boards.
Board #1 is set up with the development kit.
- I usually use Hyperterm to communicate with it over the Serial Port.
- It's the one I compile on.
- I'll also telnet or ftp to it over the ethernet
Board #2 is set up getting it's power from a custom designed board.
- I'm trying to keep it set up as "pristine" as possible so that only the
necessary setup has been done to it.
- Communication with it is done via telnet or ftp over the ethernet
Both are booting from the SD card. I am NOT a linux expert.
I have two things I have noticed different between the 2 boards.
1) The following code segment:
double nowtime;
struct timeval tp;
struct timezone tzp;
gettimeofday(&tp,&tzp);
nowtime = tp.tv_usec / 1000000.0F;
nowtime += tp.tv_sec;
FAILS with a Floating Point exception at the 2nd to last line on Board #2, but
not on Board #1. I have fixed the code so that it doesn't cause a floating
point exception - but it still bothers me the inconsistency.
2) More troubling:
On Board #2: If I try coping (even a small file) I get
cp: memory exhausted
This happens even it's pretty much the first thing I do after a reboot.
Board #1: which doesn't have any problem compiling, copying files around, etc:
# free -m
total used free shared buffers cached
Mem: 61 60 1 0 5 41
-/+ buffers/cache: 13 48
Swap: 0 0 0
Board #2: which has the problem:
# free -m
total used free shared buffers cached
Mem: 61 45 16 0 12 21
-/+ buffers/cache: 11 49
Swap: 0 0 0
I really don't know how to proceed - any help or pointers would be appreciated.
