esp_hosted_fg network_adapter

I'm trying to build the network adapter for a esp32c5 and got the following linker error:

How can get it running? Can I download a binary for a esp32c5 with SPI interface?

Hello @koellomat,

Possibly you are using old IDF setup, which did not have C5 support. In any case, if you feel some issue here, please raise you problem using https://github.com/espressif/esp-hosted/issues.

Thank you.
