Hi Fatih,
Thanks for your message. A lot of people are on holiday these days, so that’s why the response is slow. I will try to answer some of your questions as far as I can:
Markus recently made an addition ot hte user OEM commands which allow one to user the FRU LEDs, see New features in the core S/W
I am not sure how you want to use the Payload Interface. It is defined to used with IPMI messages. So far, we have only used it from the payload (IPMI request) to the IPMC (IPMI response).
I think there is a light-weight TCP server in the IPMC available, but it is probably better to wait until Julian is back from holidays to find out how it works.
Hope this helps already - more to come soon. Cheers,
Ralf
