Abstract: Firmware updates are necessary to enhance the embedded systems performance and to remove the bugs. But it’s not an efficient manner to be installed it by the technician in the field. For c2000 controllers of Texas instruments dynamic memory allocation is not possible. So, using the proposed method we can maintain both updated firmware and current running firmware for the continuity of the system operation without dynamic memory allocation requirement. In this over the air (OTA) firmware update method, both application and the secondary boot loader (SBL) handles the update process without intervention of the technician. When there is any update the current running application copies the incoming updated firmware using its linker file. After the update process when there is a system reset the SBL calculates the checksum of the updated application, if it matches with the received checksum it executes the updated firmware else it executes the current running firmware without interrupting the application operation.
