The -target-download Command

Synopsis

 -target-download

Loads the executable onto the remote target. It prints out an update message every half second, which includes the fields:

`section'

The name of the section.

`section-sent'

The size of what has been sent so far for that section.

`section-size'

The size of the section.

`total-sent'

The total size of what was sent so far (the current and the previous sections).

`total-size'

The size of the overall executable to download.

Each message is sent as status record (see section GDB/MI Output Syntax).

In addition, it prints the name and size of the sections, as they are downloaded. These messages include the following fields:

`section'

The name of the section.

`section-size'

The size of the section.

`total-size'

The size of the overall executable to download.

At the end, a summary is printed.

GDB Command

The corresponding GDB command is `load'.

Example

Note: each status message appears on a single line. Here the messages have been broken down so that they can fit onto a page.
