RE: SwissMicros DM-41
i know michael has put the instructions for firmware upgrade at his website. however, i cant't get beyond the 3rd step, i.e. how to select device LPC1115/303 ?
1. get the SwissMicros Firmware Update Tool as an EXE or zipped or get FlashMagic 2. install CP2102 driver under Windows, get it from here or here 3. select device LPC1115/303 (or LPC1114/301 for calculators sold before June 2012) 4. choose correct COM port 5. set baud rate to 115200 or lower 6. select interface: none (ISP) 7. Oscillator (MHz): 12 8. check 'Erase all Flash+Code Rd Prot' in the menu bar at the top of the FlashMagic screen, under "Options->Advanced Options->Hardware Config" check the box in front of "Use DTR and RTS to control RST and ISP pin" 9. connect the calculator with a standard miniUSB cable, preferably a shielded one. The calculator may be turned on or off before flashing push and hold the PGM button through the right-hand pinhole on the backside with a needle and press Start to flash the firmware. the PGM button may be released after flashing has started after flashing is done, push the RESET button through the left-hand pinhole on the backside I would appreciate it very much if some one could guide me thru the firmware upgrade process. Thanks! hpnut |
