Permission issues /dev/ttyUSB0
某些 Linux 版本可能在烧写 ESP32-S2 时会出现 Failed to open port /dev/ttyUSB0 错
误消息。可以通过将当前⽤户添加到拨出组来解决。
With some Linux distributions you may get the Failed to open port /dev/ttyUSB0 error
message when flashing the ESP32. This can be solved by adding the current user to the
dialout group.
Arch Linux Users¶
To run the precompiled gdb (xtensa-esp32-elf-gdb) in Arch Linux requires ncurses 5, but
Arch uses ncurses 6.
Backwards compatibility libraries are available in AUR for native and lib32 configurations:
https://aur.archlinux.org/packages/ncurses5-compat-libs/
https://aur.archlinux.org/packages/lib32-ncurses5-compat-libs/
Before installing these packages you might need to add the author's public key to your
keyring as described in the "Comments" section at the links above.
Alternatively, use crosstool-NG to compile a gdb that links against ncurses 6.
