I use ti-processor-sdk-linux-am57xx-evm-03.03.00.04 on am5728
And want to allocate buffers for capture video. My dts:
reserved-memory {
#address-cells = <0x2>;

CMEM loads fine

But sample program not works:
CMEM_AllocParams prms;
prms.alignment = 0;
prms.flags = CMEM_NONCACHED;
prms.type = CMEM_POOL;
CMEM_init();
void* ptr = CMEM_alloc(640*480*2,&prms);
printf("Got buffer %08X\n",ptr);
CMEM_free(ptr,&prms);
CMEM_exit();
CMEM Error: registerAlloc: ioctl CMEM_IOCREGUSER failed for phys addr 0xa0000000: -1
TIOCL FATAL: The TI Multicore Tools daemon (/usr/bin/ti-mctd) is not running. Re-run application after starting the daemon. Refer User Guide for details.
When try to run ti-mctd:
