Abstract: A method for automatic firmware upgrade on a target embedded system connected to a TFTP server and a web console is disclosed. The method includes generating a single image from Linux kernel image and file system image and providing single image name as input to web console for firmware upgrade. The web console write upgrade flag and single image name in the kernel configuration and issue a restart command to the embedded system. At boot up time, the start up module checks for firmware upgrade flag set and issue commands for loading the image on target board and boots up with the upgraded image. The firmware upgrade is performed over the network. Further, the embedded system is upgraded with very less user interaction reducing firmware upgrade time and by reducing dependence of experienced/skilled person.

Abstract: This invention proposes a procedure by which one or more number of IRPs (IO Request Packets) can be always kept pending with the USB Host controller in order to get the incoming data as soon as it arrives. When data arrives the USB Host Controller and driver will complete the IRP Request and the USB Client driver will buffer this data if there is no READ request pending from the application layer; else it will complete the application requests with data received from the device.
