C94-M8P - User GuideUBX-15031066 - R07 Early Production Information AppendixPage 40 of 47C.1 Updating procedurePlease download the correct firmware for your C94 variant from the u-blox GitHub website:https://github.com/u-blox/C94-application-board-radio-firmware/There are two parts to the firmware, a Boot loader (BL) and the Firmware itself (FW).1. Copy the C94 radio boot loader (BL) and firmware (FW) in the same folder as the Flash utility. Forexample with C94-M8P-4 the correct FW is -4 version. Example of the file names: BL_HM_TRP_006_04_083b97ece14eadc219bda775c5a6ccb07cfe9baf.hex FW_HM_TRP_006_04_489d3e8fbb1663f253bc49d2d32794350eaa8749.hex2. Connect the Silicon Labs debugger directly into C94 debugger interface for radio modem (J6). Note thePin 1 location on the C94 board and the Pin 1 location on the debugger connector. The debugger willpower the C94 so no need to plug in a USB cable or any other power.3. Connect the Silicon Labs debugger to a USB port on your computer4. Open a command prompt in the folder where the Flash utility is.5. For this example (a -4 radio) enter the following:FlashUtilCL.exe downloadusb –E BL_HM_TRP_006_04_083b97ece14eadc219bda775c5a6ccb07cfe9baf.hex "" 0 1Figure 35: Using the FlashUtilCL in Windows Command Prompt6. The Silicon Labs Debugger will power the radio from the USB port once the command is executed. Youwill see the Power and RUN/STOP LED's on the debugger light up as it is running and programming. TheFlash utility will then exit if it has been successful. You might need to repeat this command if the PC didnot connect properly to the debugger.7. Repeat the process for the firmware (FW):FlashUtilCL.exe downloadusb –E FW_HM_TRP_006_04_489d3e8fbb1663f253bc49d2d32794350eaa8749.hex "" 0 18. The Debugger lights will again light up as it is programming the radio and the flash utility will then exitif it has been successful. You might need to repeat this command if the PC did not connect properly tothe debugger.9. The C94 radio will need a power cycle, if you have powered the radio through the debugger it willpower it off once completed. If you have the USB cable connected, remove it and connect it again.The next step is to verify that the Radio modem runs with the new firmware. Power up the C94 board and verifythat the Green LED on the radio modem lights up. It will flash slowly if no other C94 radio connects to it. For theC94 version with a shield over the radio, simply lift off the shield. Refer to Figure 37 to see the location of theLEDs on the radio modem. If the Green LED lights up all went well.To verify the current radio firmware serial port speed, refer to Appendix B how to configure the radio. Whenconnected with your terminal software, enter ATI5 and then ATI to check the firmware version.
