<p>Nitropixie: </p> <hr /> <div>=='''Before you Start'''==<br /> '''The upgrade process for your MJLJ will erase your ignition configuration and restore the 'factory default' values.'''<br /> <br /> Before continuing, you should save your existing ignition configuration. You can do so by following these steps:<br /> <br /> #Power up your MJLJ unit<br /> #Start the MJLJ configuration software with the serial cable connected to your controller<br /> #If needed, read the controller's ignition configuration.<br /> #Click File / Save and save your configuration to a file.<br /> <br /> This file will be used later to restore your configuration after you've loaded the new MJLJ firmware.<br /> <br /> =='''Identifying your MJLJ version'''==<br /> <br /> The version of firmware you install depends on the board version you have. It is critical you install the correct firmware for your board! <br /> <br /> '''If the incorrect firmware is installed, the MJLJ will not synchronize correctly with the EDIS module and ignition timing errors will occur.'''<br /> <br /> <br /> If you don't recall the version of the MJLJ hardware you have, you can quickly remove the top four cover screws for a quick board inspection.<br /> <br /> <br /> ==='''MJLJ V4.x hardware'''===<br /> [[Image:Mjlj_v4_molex_end.jpg]]<br /> <br /> Download MJLJ V4 hardware firmware images from the [[MJLJ_V4_Downloads|V4.x download area]]<br /> <br /> ==='''MJLJ V3.x hardware'''===<br /> [[Image:mjlj_3.0.0_board_and_proc.jpg]]<br /> <br /> Download MJLJ V3 hardware firmware images from the [[MJLJ_V3_Downloads|V3.x download area]]<br /> <br /> ==='''MJLJ V2.x hardware'''===<br /> [[Image:mjlj_board_and_proc.jpg]]<br /> <br /> Download the MJLJ V2 hardware firmware images from the [[MJLJ_V2_Downloads|V2.x download area]]<br /> <br /> =='''Saving the firmware'''==<br /> To save the firmware to your computer in an easy to access folder, click '''Start''', '''My computer''', then enter the '''C: drive''' folder. When here create a folder and call it something simple such as '''mjlj'''.<br /> <br /> Save the new firmware software and the HC08sprg.exe file for your specific controller to this folder, which can be found in the links above.<br /> <br /> [[Image:drive.jpg]]<br /> <br /> =='''Installing the firmware'''==<br /> Ensure your mjlj is not powered on and you have a serial connection between controller and PC.<br /> <br /> Open a command window (Click '''Start''' / '''Run''', and enter ''''cmd'''')<br /> <br /> [[Image:Cmd.jpg]]<br /> <br /> Change the directory to where you saved your firmware files earlier at the C: prompt (Type '''cd c:mjlj''' and press '''enter''').<br /> <br /> Enter the following command:<br /> <br /> &gt; '''hc08sprg.exe COM1 mjlJunior_VX.X.X.s19'''<br /> <br /> *''Replace COM1 with the COM port your MJLJ is installed on''<br /> *''Be sure to specify the correct mjlj firmware file.''<br /> <br /> [[Image:Hc08.jpg]]<br /> <br /> The program will wait for a signal from the MJLJ processor. Once you see this message, apply power to the MJLJ- you will see some more information. <br /> <br /> [[Image:Turn_on.jpg]]<br /> <br /> You will be prompted to continue programming. If you are ready to flash the new firmware, enter 'Y'.<br /> If all goes well, you will see a progress indicator as the processor is loaded with the new firmware image.<br /> <br /> Here is a typical output from a successful firmware upgrade:<br /> <br /> c:\&gt;cd c:\mjlj<br /> c:\mjlj&gt;hc08sprg.exe COM1 mjlJunior_V3.2.1.s19<br /> Waiting for HC08 reset ACK...received 0xfc (good).<br /> Calibration break pulse sent. Count: 1<br /> Bootloader version string: KX8-IR<br /> Available flash memory: 0xE000-0xFC7F<br /> Erase block size: 64 bytes<br /> Write block size: 32 bytes<br /> Original vector table: 0xFFDC<br /> Bootloader user table: 0xFC80<br /> Bootloader data (hex): 82 80 00 00 00 66 20 f3<br /> Are you sure to program part? [y/N]: y<br /> Memory programmed: 100%<br /> <br /> <br /> =='''Finalizing'''==<br /> <br /> ===Configuration Software===<br /> You will likely need to install a new version of the Configuration Software. From the same location where you downloaded the new firmware, find and and install the matching Configuration software.<br /> <br /> ===Restoring Ignition Configuration===<br /> * Run the new Configuration Software, set the appropriate serial port and connect to the Ignition Controller. <br /> * You can verify the firmware version by clicking Help/About.<br /> * Restore your saved ignition map, and start testing the new features.<br /> <br /> ==Support==<br /> Visit our [http://www.autosportlabs.org forums] for any questions or issues!</div>
