I copied a c66 elf binary(.out) to 66ak2h12's root filesystem.
and loaded dsp application by mpmcl.
mpmcl load dsp0 dsp_application.out
but an error is occurred as follows.
[ 52.774873] rproc-user dspmem.3: mmap offset 0x80000000 is outside the allowed range
load failed (error: -104)
dsp applications' MEMORY CONFIGURATION is as follows.
| name | origin | length | used | unused | attr |
| L2SRAM | 00800000 | 00100000 | 000ef9f0 | 00010610 | RW X |
| MSMCSRAM | 0c000000 | 00600000 | 0056b97e | 00094682 | RW X |
| DDR3 | 80000000 | 80000000 | 021f4000 | 7de0c000 | RWIX |
i did two tries to solve this problem that ARM side cannot recognize the memory region which dsp side uses.
first, edit U-boot env 'mem_reserve = 1536M' to get more dsp's available memory.
next, change /etc/mpm/mpm_config.json as follows.
"name": "local-ddr",
"globaladdr": "0x80000000",
"length": "0x80000000",
"devicename": "/dev/dspmem"
but the problem is still there.
how can i load a dsp application which uses ddr3a memory while arm linux is running?
