    Hi, Vishal,

    the dspmem currently specifies load address of 0xa0000000, and mpm_config.json file has the corresponding ddr memory address. Both need to be modified for the change.

    The DSP log messages can be read from following debugfs locations

    DSP log entry for core #: /debug/remoteproc/remoteproc#/trace0

    Where # is the core id starting from 0.

    root@keystone-evm:~# cat /debug/remoteproc/remoteproc0/trace0 Main started on core 1 .... root@keystone-evm:~#
