Hi,
We are facing problem while running our application over the
DVEVM.
1. We are able to run our application code properly in CCS V3.3
with XDS510 USB Emulator on the DVEVM .The DDR memory location and
length used in the cmd file is 0x8FA00000 and 0x400000 respectively.
2. We are using the same code for processing the BMP image buffer
in the ReadWrite example available with DSP/BIOS Link, this is done by
calling our application in TSKRDWR_execute () in the tskReadwrite.c file
after line No.183 and we are writing the BMP Image buffer read in ARM
side into the DSP memory in RDWR_Execute() in readwrite.c. Since size of
our code for processing the image is more than the code available in
this example we had to move to the code to different location in the DDR
memory by changing the DDR segment location and length available in the
"dsplink-davinci-base.tci" and "CFG_Davinci.c" file to the value
0x8FA00000 and 0x400000 respectively from the default value of
0x8FF00080 and 0xFFF80.
3. Our Image buffer size is 84000 bytes and we are writing it at
the DSP Memory location 2414563328(0x8FEB5000).
4. When we are trying to run this modified readwrite example it is
getting executed and then when it is calling up our application then it
is hanging up.
5. We have even tried using other different memory segment of the
DDR memory for loading the code and writing the Image buffer in the
DSP memory but that also did not help us.
6. Are these memory related changes that I have made Ok or we need
to do something else.
If anyone can Please help me out in resolving this issues. Thanks in
advance for the same .
Thanks n Regards
Manish Singh Bisht
