2. Updating the boot loader
Check your current I32/PRE32 firmware version by turn ON the unit and enter the MENU.
If your I32/PRE32 is using firmware version 1.74 or later, you do NOT need to update the boot
loader. Instead, continue to 4. Updating I32/PRE32/MM30 firmware via Internet
2.1 Connect a null modem cable (or the recommended USB-RS232 cable) from your computer to the
I32/PRE32.
2.2 Power ON the I32/PRE32. It must be active.
2.3 Press and hold ‘MENU’, ‘ENTER’ and ‘BACK’ buttons on the front panel at the same time. After a
while it writes out the firmware version and a little later it “clicks” and blanks the display
(backlight is still on for all the button icons).
2.4 Now the I32/PRE32 is ready for programming and you can release the buttons.
2.5 Start program FlashSta.exe (located in the “Boot loader” folder)
2.6 Choose “Internal Flash memory” and choose the COM-Port you are using. Click “OK”.
If you get an error message almost directly after pressing “OK” – Just press “OK” and try again
with same baud rate.
If there is no connection you will get an error message after a few seconds. The reason for this
may be that you have chosen the wrong COM-port or the cable is not working correctly.
2.7 Click “Refer” and locate the “bootloader.mot” in the “Boot loader” folder.
2.8 The text “can’t find the ID file” will appear.
Click OK and fill in “FF FF FF FF FF FF FF” in the ID field.
2.9 Click OK and a new window pops up.
Click “Erase” to remove the old SW from I32/PRE32. After a while it says “Erase OK”. Click OK.
2.10 Click “Program” and click “OK” again to the popup window. Now the I32/PRE32 is being
programmed. It takes a little while.
2.11 When finished a popup window appears saying “Program OK”. Please Click OK.
2.12 Now the bootloader is programmed. Close Flashsta.
2.13 Switch off the I32/PRE32 using rear power switch. (If you try to start the unit, it will appear
dead, because there is no firmware intalled!)
2.14 Continue with step 3. Updating I32/PRE32 Firmware via RS232 on the next page.
