Abstract
An integrated-circuit radio communication device (1) comprises processing means (7), memory (13), and radio communication logic (17). The memory (13) stores (i) a boot-loader (22), (ii) a firmware module (23) in a firmware memory region, and (iii) a software application (27) in a software-application memory region. The firmware module (23) comprises instructions for controlling the radio communication logic (17) according to a predetermined radio protocol, and the software application (27) comprises instructions for invoking a radio-communication function of the firmware module (23). The boot-loader (22) or the firmware module (23) comprises instructions for using the radio communication logic (17) to receive a new firmware module (40), and the boot-loader (22) or the firmware module (23) comprises instructions for storing the new firmware module (40) in the software-application memory region such that at least a portion of the software application (27) is overwritten by the new firmware module (40). The boot-loader (22) comprises instructions for moving or copying the new firmware module (40) from the software-application memory region to the firmware memory region.
