Deat Intel
I prepare Ubuntu 14.04 LTS. and download Intel RSD Git last ver. 2.2.
I follow 335460-003 PSME user guide "3 , PSME Develop Enviroment"
installed PSME packages and its agents, and use root.crt as ca.crt and generate server.key and ,crt,
"rmm-present" is false,
run PSME REST server success,
sudo ./psme-rest-server ../../application/config/psme-rest-server-configuration.json

but run psme-compute have error message
sudo ./psme-compute ../../agent/compute/configuration.json

Hi @housemic,

The PSME Compute Agent requires communication with the Cypress USB to I2C driver, which is provided by the cyMUX service. Your problem with the service could be hardware related, what is further explained in the issue #35 .

Dear tbykowsk

1. Do I need to prepare the hardware CY7C65215 device to startup PSME compute agent ?
2. If I don't have the hardware CY7C65215 device, Can I startup PSME compute agent ?
   thank you

1. The reference PSME Compute Agent depends upon the cyMUX service, which requires a CY7C65215 device.
2. However, you can modify the reference source code not to require the communication with cyMUX. It may take some effort to adjust the PSME Compute Agent code to your specific hardware, but it should be possible.
