Abstract
A method for upgrading firmware in an embedded system and an embedded system (110) provided with means for upgrading firmware received over a network (30) are disclosed. The method for upgrading firmware is performed from a client computer (10) to the embedded system (110) via a network connection by letting a virtual file system (122) of the embedded system (110) being shared with a client computer (10).The embedded system (110) is provided with means for upgrading firmware received over a network (30), and comprises a volatile memory (150), a persistent memory (160), a protocol stack (180) for communication over a network (30). Further it comprises a virtual file system (122), which is shareable with an operating system of a client computer (10) via the network (30), and a control means (128) for controlling a file intended for the virtual file system. Further the control means (128) comprises means for checking the characteristics of the file, and means for storing a file in the volatile memory.
