The window size defaults to 1. + +If CONFIG_TFTP_TSIZE=y, the progress bar is limited to 50 '#' characters. +Otherwise an '#' is written per UDP package which may decrease performance. + +Return value +------------ + +The return value $? is 0 (true) on success and 1 (false) otherwise. diff --git a/doc/usage/index.rst b/doc/usage/index.rst index 28f9683a3e6..f1beeec59c9 100644 --- a/doc/usage/index.rst +++ b/doc/usage/index.rst @@ -63,6 +63,7 @@ Shell commands cmd/scp03 cmd/setexpr cmd/size + cmd/tftpput cmd/true cmd/ums cmd/wdt |
