Tool/software:
Hi all,
This post related with "processors-forum/991591"
I used both Linux and RT 6_03_00_106 to build this example (Big Data IPC). However, when I try to load the server_dsp.xe66 file (copy from bigdataipc/host_linux/simple_buffer_example/dsp/bin/66AK2G/release) with the mpmcl command I get error 104. The corresponding messages from the /var/log/syslog are as follows:

This address (0xA0000000) is specified in the source code of the example as EXT_CODE region host_linux/simple_buffer_example/shared/66AK2G/config.bld
There are two questions:
(a) how should I describe this memory for the EXT_CODE in the DTS?
(b) where can I find the source code for the command mpmcl, mpmsrv and related with it?
Thanks.
