[Fixed] Bootloader Install not working

[Bairkan]

I have built my kit, but when it comes to flashing the bootloader I have connected the USB, installed dfu-util through macports, but when I try to run the command to install the boot loader, it tells me that no DFU-compatible USB device has been found, I have shorted the jumper 3, so that shouldn't be the problem.

[Bairkan]

I have now connected the USB cable to the FEZ Cerb directly and it now shows up when executing the dfu-util -l command, yet when I try and flash the bootloader dfu-util brings up an error "No valid DFU suffix signature Warning: File has no DFU suffix", this is when using the command:

dfu-util -a0 -d 0×0483:0xdf11 -D /Users/me/Downloads/build/p2_boot_1.01.bin -R -s 0×8000000

I have now connected the USB cable to the FEZ Cerb directly and it now shows up when executing the dfu-util -l command,

Thanks for checking this.
So the USB cable you made does not work... you may have a shortcut or solder the wrong pins on the mini usb socket.

yet when I try and flash the bootloader dfu-util brings up an error "No valid DFU suffix signature Warning: File has no DFU suffix", this is when using the command:
dfu-util -a0 -d 0×0483:0xdf11 -D /Users/me/Downloads/build/p2_boot_1.01.bin -R -s 0×8000000

The -s options should tell dfu-util to consider the file as a raw file.. that's strange it check the DFU suffix.
Could you let me know the full output of "dfu-utils -l"  and "dfu-util -h" ?

Well, I have fixed the error with the address, had to replace the "x" in the command for the memory address with a character x, now I get this result:

Resetting USB to switch back to runtime mode

OK So you got it.
Flash bootloader AND firmware.

Code: [Select]

dfu-util -a0 -d 0×0483:0xdf11 -D /Users/maxvoetsch/Downloads/build/p2_boot_1.01.bin -R -s 0x8000000
dfu-util -a0 -d 0x0483:0xdf11 -D /Users/maxvoetsch/Downloads/build/p2_09h.bin -R -s 0x8040000

Remove JMP3.
Reboot...  should be OK.

> "can't detach - Resetting USB to switch back to runtime mode"

Is not a problem.

[Bairkan]

I have executed both commands, removed the jumper and restarted, yet the screen is still blank and when connecting a MIDI keyboard and speakers there is no sound, so I assume there still is some problem with the software persisting, any pointers?

If you see the points appearing while uploading both the files... The firmware is uploaded.

Have you tried to turn the variable resistor of the LCD contrast in both direction ?
If yes it seems that your CERB40 / PreenFM PCB are not correctly connected, which also must be the reason why you could not upload the firmware with the main USB cable.

Check it's well inserted and that the DIP 40 socket is well soldered on the PCB.

Xavier

[Xavier]

Try to turn on the PFM without the PCB->CERB40 USB custom cable and without the midi pins plugged.

And my last idea of the day : have you double checked you flashed the bootloader at 0x8000000 and the firmware at 0x8040000 ?

Let me know how it goes,

Xavier

[Bairkan]

Okay, so I have gotten it to work as far as it starting up and showing the screen saying "PreenFM2 v0.9h By Xavier Hosxe", seems stuck at that though. I fixed the USB cable so now I can flash from the regular port, seems the connectors were not working properly, the cable was still isolated where it should have connected to the metal, manufacturing fault, I guess.

Which is good. It passes the bootloader and is now in the firmware.
I think it's stuck on the USB drive initialization.

Do you have a USB stick plugged ? Did you extract on it the file you can find in the Download tab ?

Xavier

[Bairkan]

I have one in there, with the file available from the download, I guess I'll reformat the drive and try again and if that doesn't work maybe try another drive since I got a couple spares lying about.

[Bairkan]

Had to use a different USB drive but now it is all working, thanks for the help Xavier, I'll gladly recommend your products to anyone else interested in DIY synths.
