9. Upgrade software method Instructions for flashing firmware 1. Disconnect any peripherals connected to the parallel port on the computer. Disconnect the DVI cable from the computer 2. Connect the DVI cable to the DVI to VGA adapter, and then connect the VGA side of the adapter to the ISP board. Connect the ISP board to the computer with the supplied parallel cable. (check Jumper No.4 and No.8 of SW3 to be ON at ISP board, the rest of all to be OFF). Connect the mouse and keyboard to the computer.
4. On the flash drive you will find a folder named “ISP program for Mstar TSUM_write_code”, open it and start ISP_Tool_3.75.3.exe 5. Press connect. A pop‐up window showing “Device type is MX25L512” should appear. If the pop‐up window say “Can’t entry ISP mode” recheck the cables. LT1201 User Manual (020-1080-00 Rev.
6. Next press the big red button on the top, and then press the smaller read button 7. Select the AU5T015QT1_1E0A.BIN and open. LT1201 User Manual (020-1080-00 Rev.
8. Check and re‐check the Checksum. It should be 0x1E0A. 9. Press the Auto button right next to the read button. Check that the setting is according to picture above. 10. Press “Run”. The program will start to erase and reprogram the firmware. Sometimes the programming fails, if that happens, just restart the process by hitting “Run” again. When the ISP board is cold this can happen a couple of times before you get a successful run. 11.
