Patent number: 11321222Abstract: Techniques are described for debugging node devices. A node device may be connected to a host device for debugging purposes. A debugger, providing debug functionality, such as a debugging web application, may run on a remote server and be accessed via a web browser running at the host device, to debug the node device. Alternatively, the debugging web application may execute in the web browser running at the host device to debug the node device. In another alternative, the debugging web application may execute at a gateway device provided between the node device and the host device. In all cases the debugging web application is controlled via a debug user interface running at the web browser. Consequently, a user of the host device is not required to install a debugger at the host device in order to debug a node device.Type: GrantFiled: October 7, 2019Date of Patent: May 3, 2022Assignee: Arm IP LimitedInventors: Robert James Moran, Arkadiusz Pawel Zaluski
