ok im about to look kinda stupid here (again?) and ask: bootloader... does it reside on the computer or the cerb40? bootloader is what i need to load the firmware? i know the firmware resides on the cerb40. bootloader is what looks for firmware in /pfm2?
when i run "dfu-util -a0 -d 0x0483:0xdf11 -D p2_boot_1.10.bin -R -s 0x8000000" it says "could not open file p2_boot_1.10.bin for reading: No such file or directory" is this because the cerb40 cant find the thumb drive?

display is OLED
nothing has been flashed. i need step by step instructions.
it says download firmware... but to where?
dfu-util -l lists UNKNOWN, @Device Feature, @OTP Memory, @Option Bytes, @Internal Flash
so im sorry, did you say you need to directly hook up the cerb40 to the computer from its USB port? ok did that. still when i run "dfu-util -a0 -d 0x0483:0xdf11 -D p2_boot_1.10.bin -R -s 0x8000000" it says "could not open file p2_boot_1.10.bin for reading: No such file or directory"
what format does the thumb drive need? fat32 or fat16?
also, should these files be in /pfm2/ or some other direcory?
thanks

dfu-util is available from MacPort or brews.
MacPort : Install MacPort. With Macport install dfu-util and you’re ready to run the dfu-util command.
Breaws : run the installation command at the bootom of the brews home page… Then ‘brews install dfu-util’.
Boot microcontroller in DFU mode.
Have you preenFM unpluged
Shortcut the Jmp3 connection.
Power up with the USB connector
Nothing on the LCD is normal. The STM32F4 is in DFU mode.
Downlad the last PreenFM2 firmwares from the download page.
Then goto 4 to run the commands.

ok i got dfu-util and command line utils from apple installed. im stumped. i think im supposed to have a directory on the thumb drive called pfm2 with the bootloader and firmware in it and when i try to CD over to that folder it says no such directory.
i can also hook up USB to the cerb40 and flash directly right? how do i do that? i need it spelled out my apologies but i just dont ever do this or anything remotely similar... the instructions are like french to me. no pun intended. well ok pun intended
. i only speak english
when i plugged the unit into my xp machine it wanted a driver so that means it works right?
also, when i plug usb or 9v power into the unit and the jmp3 is not closed, the LED lights light up dimly. is this a bad sign? the screen has never come on once yet. i wish there was another indication that something was working.

hi, collecting parts for the preenfm2. i have most of them but not the main board or case that i ordered... is there a way to track its progress?
im quite excited about using the LFOs in pfm2 since there just isnt any decent LFO action in any yamaha design. which is too bad if you ask me since LFOs are where the mojo is!
