I am using OMAP L138 EVM . I modified memory map configuration for 'read-write' application by increasing the DDR(CODE/DATA) memory space.
But when I am trying to run the program, I am getting the following error.
Entered RDWR_Create () Leaving RDWR_Create () Entered RDWR_Execute () PROC_write Failed. Status: [0x80008013] PROC_write Failed. Status: [0x80008013] Leaving RDWR_Execute () Execute phase failed. Status: [0x80008013] Entered RDWR_Delete ()Initially size of DDR memory space was 0xFFF80, since my application requires more space I doubled the memory size to 0x1FFF00.
Because of that, the buffer area(POOLMEM) which is using for read write operation is now shifted to address starts at 0xC402FF80.
Initially POOLMEM area was from 0xC3F30000 to 0xC4000000.
After the memory changes, when I am trying to access the memory area from 0xC402FF80, getting the above error.
I modified the CFG_OMAPL138GEM_SHEM.c and dsplink-omapl138gem-base.tci files for the memory changes. I am attaching those files here.
Is there any problem for accessing memory area after 0xC4000000 , On the below link I read that the DDRALGHEAP area is within the
range 0xC3000000 - 0xC3FFFFFF for 64MB memory configuration.
Since OMAP L138 has 512MB of DDR2 memory, what this 64MB configuration?
Please help me to solve the problem.
Thanks in advance
I am managed to solve that problem. After changing memory configurations, I rebuild the entire DSPLink modules.
This solved the problem. Initially I rebuild only my application, that's why I got the above errors.
The OMAP L138 EVM from LOGIC ZOOM supports 128MB of DDR2 memory.
