Description

Describe the solution you'd like Create host emulator for CLI/OC-admin. Idea is to run the OCWare without the need of physical hardware.

Is your feature request related to a problem? Please describe. In order to fully test CLI it would be useful to have a full emulator to break dependency on hardware for tests.

Originally commented by mayuri2016 Added few comments on this feature requirement. Will call for discussion to explore this option more and feasible solution.

Proposed Functionality Details:

This capability will provide host emulator platform removing dependency of actual physical hardware.

• Required transmitter which can generate OCMP packets as its generated by host SW to send to firmware • Required receiver to receive these packets, validate the packet content and send response back • Transmitter can be either a host Linux machine where CLI SW can be run and OCMP packets can be generated • If there is need to explore additional functionalities for Intel, option for qemu emulator can be checked. But only for OCMP packets testing, this may not be required. • Checked for TI microcontroller emulator- currently there is no open source simulator available for these low cost microcontroller. Keil or IAR provides this feature, but that comes with a license. • TI recommends to use Launchpad to emulate tiva microcontroller as its most easier approach.

For the receive part, below 4 ways can be explored: o Use TI DK Launchpad to receive OCMP packets and send response, while other HW functionalities can be stubbed out o If its just needs to be sw component to send/receive OCMP packets independent of TIVA, current host sw can be customized to make it work like this. o Unit test framework might be doing similar functionalities for host sw- receiving commands from CLI and sending back dummy reply

Originally commented by samudhira We implemented OCWARE_STUB application to stubbing the config and status parameter values requested from the CLI application. In that, we are using Ethernet UDP communication to send/receive the message frame from/to middleware application. So far we have implemented config and status parameters for all te subsystem. Now we are in under discussion for command, alerts and other parameters.
