Unable to Load and boot DSP from ARM (remoteproc) - TCI6614

Hi,

I'm using TCI6614EVM board and trying to load the sample executable given in /lib/firmware to DSP core 0. But I'm not able to find the sysfs entry for the DSP cores. Why the drivers are not loading properly?

I have attached the kernel boot prints and dmesg command output for your reference.

    Joseph:

        Please check your MCSDK documentation, but I recall when I worked on this device (with my version of MCSDK), the command was:

    echo "running" > /sys/class/remoteproc/dsp-core0/state

    Regards,

    Hi Gil,

    I'm using SC-MCSDK Ver 2.0.0.8 and in the user guide it is mentioned that sysfs entries are found in /sys/devices folder.

    Did you check the boot logs, when I compared with the sample logs given in the mcsdk user guide document I'm not able to see the keystone_hwqueue, keystone_remoteproc related prints. I suspect remoteproc kernel drivers are not loading properly. Can somebody tell me whats happening?
