problem while running code on h/w

Started by hrihshikesh rajurkar ●September 15, 2005
hi all,
We are building an image processing application on
dm642. The code works fine on simulator but while
running the same code on h/w (dm642 eval board with
ccs
3.0.0.21),I am getting the following errors
/* errors*/
Error: Error 0x0000000C/-2044 Error during: Register,
Break Point, No breakpoint at 0x74000000 Sequence
ID: 16 Error Code: -2044 Error Class: 0x0000000C
Trouble Halting Target CPU: Error 0x0000000C/-2044
Error during: Register, Break Point, No breakpoint at
0x74000000 Sequence ID: 16 Error Code: -2044 Error
Class: 0x0000000C
/*errors message ends*/
As our .text size is quiet large (1663360) i am
loading it to external ram, cmd file of mine is as
follows
/* cmd file*/
-heap 0xFFFFF1

MEMORY
{
IRAM : origin = 0x0, len = 0x40000
EXT : origin = 0x80000000, len = 0x10000000

}

SECTIONS
{
.cinit > IRAM
.text > EXT
.stack > IRAM
.bss > IRAM
.const > IRAM
.data > IRAM
.far > EXT
.switch > EXT
.sysmem > EXT
.tables > IRAM
.cio > IRAM
/* cmd file ends */
Pl. throw some light on the issue and also on
simulator it is taking quiet a large time (10 mins
/frame of 320*240 of bmp).
thanks in advance

hrishikesh,
 
These are my thoughts and comments...
 
1. the amount of memory that is available to the simulator can easily excede the amount that the hardware provides.
2. 'EXT        : origin = 0x80000000,  len = 0x10000000' indicates that you have 268,435,456 bytes of external memory.  Is this true??
3. '-heap 0xFFFFF1' - what is this about??  I just just curious about the odd heap value [16,777,201bytes].
4. 'No breakpoint at 0x74000000' - this is most likely an indication that your code is in the weeds - I think that the memory at this address is supposed to be buffer memory.  Did someone try to set a breakpoint there??
