VFS over UART

Postby apuder » Mon Apr 01, 2019 5:50 pm

Hi,
as I understand, it is possible to use VFS over UART on the ESP. This is not strictly an ESP question, but there must be a matching "server" component that runs on the other end of the serial connection (on the host) and that performs the file I/O on that side. Can anyone point me to such a server-side implementation (Ubuntu/Mac/Windows)?
TIA,
AP

The “UART“ VFS in IDF implements something similar to tty devices on Linux (/Dev/tty X)。It does not offer semihosting features。However you may try the new feature of semihosting over JTAG: https://github.com/espressif/esp-idf/bl ... /README.md

To clarify Ivans response: you're reading the order wrong. The VFS is not tunneled over UART; the UART is accessible as a node in the VFS.
