If you find the speed too slow, once you have it running properly at 9600, then you can increase the speed back up one step at a time (on both ends) and find the maximum serial rate for your setup that works properly. The Ubuntu 14.04.2 LTS release also contains various stable bug/security fixes relevant to the platform. This new Ubuntu 14.04 LTS release includes an updated kernel and X stack for better supporting new hardware across all of Ubuntus supported architectures. By locking the baud rate down to 9600, you wake sure the SUT serial kgdboc keeps up on the target, and the problem you are seeing usually goes away. Ubuntu developer Adam Conrad announced the release of Ubuntu 14.04.2 LTS. The data sent/received by the kernel debugger is small, and even the serial console doesn't generate a lot of data in debug situations. (Everyone starts at MAX, or 57600, or 34K, or 19200), but drop it to down to 9600. This type of image is what most people will want to use.

Desktop image The desktop image allows you to try Ubuntu without changing your computer at all, and at your option to install it permanently later. SECOND, and the typically required best solution in my experience is to lower the baud rate down to 9600. Ubuntu 14.04.2 LTS (Trusty Tahr) Select an image Ubuntu is distributed on four types of images described below.

So the manual test will appear to work (no real flow control with a manual test, but it does prove you have correct baud rate control on both ends and complete control). Unfortunately, in my experience, the even with the correct RTS/CTS hardware flow control dongles interspersed, the KDBG agent on the target doesn't handle flow control well. That stack can be enabled manually, but may also be pre-enabled with an Ubuntu LTS release. As a Long Term Support release, Ubuntu 14.04.2 includes an updated hardware enablement stack that includes the 3.16 Linux kernel and an updated version of the Xorg display server. The Ubuntu LTS enablement, or Hardware Enablement (HWE), stack provides the newer kernel and X support for existing Ubuntu LTS releases. n wonвЂ™t install on Ubuntu 14.04 Trusty with the 3.18.1 Linux kernel from vivid, since trusty has GCC 4.6 and vivid has GCC 4. (Check your baud rate match, and that characters appear to transfer between the two systems OK manually). Ubuntu kernel lifecycle and enablement stack. FIRST, check the serial connection manually using a program such as minicom, setserial, and sty. The вЂњunrecognized item timeout in qsupported responseвЂќ error message most typically occurs when the serial connection between the debug station (GDB host) and target (SUT) is not running reliably in my experience.
