Additional information and things you've tried:

you would need to install the toolchain - this post may help

Alternatively, just install the HomeAssistant and configure ESPHome on that, it just works :-)

When compiling esp32 board firmware ,the plartformio will download toolchain-xtensa32 automaticaly under .platformio/packages .And the package.json is below

"description": "GCC for SoC Xtensa L108",
"name": "toolchain-xtensa32",
"system": [
"linux_armv7l",
"linux_armv8l",
"linux_aarch64"
],
"url": "https://github.com/espressif/esp-idf",
"version": "2.50200.80"

According to this information ,this pacakage is ok with arch64 linux operation system. But when compiling, the logs suggest that xtensa-esp32-elf-g++ is not found. However this file is under .platformio/packages/toolchain-xtensa32/bin . So I compile xtensa-esp32-elf following the issue you mentioned above.After replacing some folders in toolchain-xtensa32 using the files I compile ,esphome works.So I think the problem is with toolchain-xtensa32.

Yes I think the official aarch64 toolchains are broken for some users (but only for certain setups when a specific dynamic library is missing, which has prevented me from sending the patch to platformio directly).

You can use these steps to manually download a toolchain I compiled to run on native aarch64 without armv7 compatibility systems: https://github.com/esphome/esphome-docker-base/blob/master/aarch64/Dockerfile#L36
