Call failed: MCTP Endpoint did not respond: Qemu CXL switch with mctp-1.0

[Maverickk 78]

Hi

 I am trying mctp & mctpd with aspeed +buildroot(master) + linux v6.2
with Qemu 7.2.


I have added necessary FMAPI related patches into QEMU to support CLX
switch emulation

RFC-1-2-misc-i2c_mctp_cxl_fmapi-Initial-device-emulation.diff

RFC-2-3-hw-i2c-add-mctp-core.diff

RFC-4-4-hw-misc-add-a-toy-i2c-echo-device.diff

RFC-2-2-arm-virt-Add-aspeed-i2c-controller-and-MCTP-EP-to-enable-MCTP-testing.diff

RFC-3-3-hw-nvme-add-nvme-management-interface-model.diff


Executed following mctp commands to setup the binding,

mctp link set mctpi2c15 up

mctp addr add 50 dev mctpi2c15

mctp link set mctpi2c15 net 11

systemctl restart mctpd.service

busctl call xyz.openbmc_project.MCTP /xyz/openbmc_project/mctp
au.com.CodeConstruct.MCTP AssignEndpoint say mctpi2c15 1 0x4d


 The above busctl configuration is reaching fmapi patch and sets up
the endpoint id but then mctpd fails with log after timeout.

Call failed: MCTP Endpoint did not respond

Any clue what's going on?
