You get this error when the pod you use is different from the part to which the project has been cloned. If you have cloned the project to 29x66 family, you have to use the 29x66 family pod to debug the project. The pod that you used to debug the 27x43 project will not work for the 29x66 project. Also, when cloning the project, always accept 'Update Project' notification. Only when the project is updated, the project will get the new boot.tpl and the new device configuration information. Without the Update, if the project is closed, it will revert back to the older device.
