supporting remoteproc?

[linhz0hz]

I am not very experienced, but I think a major feature of the mp1 series is the MCU which can communicate fast with host. It seems this is not supported by these images? Would you mind to hint to me how should I solve this problem / add this support?

Answering my own question after some search. https://community.st.com/t5/stm32-mpus-products/missing-dev-ttyrpmsg0/td-p/106946
It seems that ST changed their handling of RPmsg and the old prebuilt ubuntu here probably no longer works with latest stm32cube library for the M4. I reverted to 1.4 of the stm32cubemp1 and it worked.
Also, this image does not allow ssh root login in default, but stm32cube requires that.
I am wondering what should I update on the A7 end? Is it linux or gcnano-binaries ?
