Once hello world is launched.. stm_master gets terminated..

Could you try modify the app json as reference from 6.0.10.

Also, can you share Logfolder and used command.

Which app JSON r u referring to from 6.0.10 ?

stefan65 · March 26, 2025, 10:28am

./apps/cgf_demo/CGFDemo.app.json
This one from sample.. (Sure will give a try).

stefan65 · March 26, 2025, 10:56am

Took Demo.app.json(modified it). Same result.

I don’t see the processPass() function being invoked.

dwStatus HelloNodeImpl::processPass()
{
    DW_LOGD << "Hello from HelloNode!" << Logger::State::endl;
    return DW_SUCCESS;
}

Any settings.. I may be missing ?

Thank you for sharing the json files. I will check the issue on DRIVE OS 6.0.10 and get back to you.

Attempt to provide cleaner logs… (process.log and schedular logs will clean jsons, yaml and stm file)

Result is same as previously reported (dwStatus HelloNodeImpl::processPass() not getting called)

Where auto-generated registerPasses looks like this..

void HelloNodeImpl::registerPasses()
{
    DW_LOGD << "Hello from HelloNode! RegisterPasses " << Logger::State::endl;
    using dw::core::operator""_sv;
    NODE_REGISTER_PASS("PROCESS"_sv,
        [this]() -> dwStatus {
            return processPass();
        });
}

Dear @stefan65,
As I understand from logs, you could run the node with out any issue but you don’t see prints from processPass() function. I expect the prints to come with DW_LOG_VERBOSE flag as you have used.
If so, can you confirm if the libs(libpebble_node.so) are copied to target after you have made changes in processPass() and compiled again.

stefan65 · April 9, 2025, 6:47pm

Yes, it’s part of the process to always copy libpebble_node.so to the target.
DW_LOGD in processPass was added first and then I added DW_LOGD to constructors to debug what all passes are called.

So I could see additional log added afterwards…
