From mboxrd@z Thu Jan 1 00:00:00 1970 From: Simon Glass Date: Sat, 18 May 2019 11:59:44 -0600 Subject: [U-Boot] [PATCH 07/17] sandbox: Quit when hang() is called In-Reply-To: <20190518175954.262021-1-sjg@chromium.org> References: <20190518175954.262021-1-sjg@chromium.org> Message-ID: <20190518175954.262021-8-sjg@chromium.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de It doesn't make a lot of sense to hang on sandbox when hang() is called, since the only way out is Ctrl-C. In fact, Ctrl-C does not work if the terminal is in raw mode, which it will be if the command-line has not been reached yet. In that case, Ctrl-Z / kill -9 must be used, which is not very friendly. Avoid all of this by quiting when hang() is called.
