I don't think the above is your actual command being used. I say this because your console output shows 2 blocks being used:

Reference Linux version 2.6.18
File /home/xia/ipc2.6/dvsdk_2_10_01_18/linuxutils_2_26_03_06/packages/ti/sdo/linuxutils/cmem/src/module/cmemk.c
allocated heap buffer 0xc4000000 of size 0x2bf2000
CMEM Range Overlaps Kernel Physical - allowing overlap
CMEM phys_start (0x1000) overlaps kernel (0x80000000 -> 0x82d00000)
allocated heap buffer 0xc3400000 of size 0x60000

In addition to two heap buffers being created (one for each physically-contiguous block), we can see the "phys_start(0x1000)" which is showing that one of your CMEM blocks was specified to start at 0x1000 (which is typical for DM365 DVSDKs).

I just wanted to point that out, that what you seem to think is your cmemk.ko insmod is not actually the one being used. Somewhere in your DVSDK is a file that does 'insmod cmemk.ko' (or 'modprobe cmemk.ko') with both phys_start/phys_end *and* phys_start1/phys_end1.

But on to your real problem - failure of CMEM allocations...

We can see that these failed allocations are "heap" based. In CMEM there are pools, which you specify with pools=..., and the heap, for each block. The heap is constructed from memory left over in the physical block after all the pool specifications have been processed. We can see that your heaps are of size 0x02bf2000 & 0x00060000 (that 2nd one confuses me - usually the 2nd block for CMEM on a DM365 is phys_start1=0x1000 phys_end1=0x8000, just 28K in size, so not nearly enough room for a heap block of 0x00060000).

When CMEM memory is allocated through Codec Engine (CE), the CE Memory interface specifies what type of allocation (POOL vs HEAP, CACHED vs NONCACHED, etc). The function Memory_alloc() takes a Memory_AllocParams structure, and one of those elements is the Memory_type. To get heap-based allocation, you would specifiy Memory_CONTIGHEAP for the type (and Memory_CONTIGPOOL if you want to alloc from one of the "pools=..." specified on the insmod command line). There is also the Memory_contigAlloc() API that essentially hardcodes Memory_CONTIGPOOL.

I get the sense that you want Memory_CONTIGPOOL allocations here. Without that, all your allocations will come from the heap, and all the pool blocks are left unused.

Also, one other mini-confusion...

...snip...
CMEMK Error: ioctl: failed to allocate heap buffer of size 0x15180

The size 0x15180 looks suspiciously like one of your pool sizes, 1x15180 (from your suspected-not-in-use 'insmod cmemk.ko'), but the pool size is in decimal and your failed allocation is printing hex. I just wanted to point this out, as it's easy to wrongly assume that the pool sizes on the insmod command are in hex (that 'x', which means "by" as in 2x4, leads folks to think the number is hex). The pool sizes are <#>x<decimal size> on the insmod command. The first size I quote directly above (0x151800) has one more '0' than 0x15180, so I wonder if that is a cut-and-paste mistake, or you're specifying an extra '0' (or you really do mean 0x15180 and 0x151800 and this is all just a huge coincidence with the decimal 15180).
