I am trying to configure a RPi4-based programming environment for embedded systems programming.
I chose neovim as a primary editor due to ability to work with both "desktop" (with monitor and keyboard attached) and headless (remote, with ssh connection only) modes + availability of many modern IDE features, but I still learning how to configure it and how to be productive with it.
I am trying to use packer.nvim as nvim's plugin manager and lsp-zero.nvim as some sort of meta-plugin which brings together few other autocomplete-related plugins, such as (nvim-cmp, nvim-lspconfig, mason.nvim) and enables autocompletion.
This bundle allows to manage language servers easily, for example, in order to install C++ autocomplete engine one just needs to run :LspInstall clangd command.
The problem is that clangd seems to be unavailable for aarch64 in this setup (the error message is "The current platform is unsupported"), however I can install clangd into the system using snap package manager, so I am sure there must be some way to make externally installed clangd server working with neovim (perhaps in a bit more hands on way), but everything I tried so far didn't work.
I configured clangd in .lua files:
local cfg = require('lspconfig')
cfg.clangd.setup({})
Here is output of :LspLog when trying editing C++ source code:

but no further attempts to call the autosuggestions server.
Here is :LspInfo output:
