From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephen Warren Date: Wed, 27 Jan 2016 23:57:49 -0700 Subject: [U-Boot] [PATCH 4/9] test/py: check for bad patterns everywhere we wait In-Reply-To: <1453964274-9129-1-git-send-email-swarren@wwwdotorg.org> References: <1453964274-9129-1-git-send-email-swarren@wwwdotorg.org> Message-ID: <1453964274-9129-4-git-send-email-swarren@wwwdotorg.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: Stephen Warren Currently, bad patterns are only honored when executing a shell command. Other cases, such as the initial boot-up of U-Boot or when interacting with command output rather than gathering all output prior to the shell prompt, do not currently look for bad patterns in console output. This patch makes sure that bad patterns are honored everywhere. One benefit of this change is that if U-Boot sandbox fails to start up, the error message it emits can be caught immediately, rather than relying on a (long) timeout when waiting for the expected signon message and/or command prompt.
