[Fixed] Flashing the Bootloader in a Mac with Mavericks

[Xavier]

It hangs with a USB upgrade message (I'd previously copied the 2 bin files onto it)

Where did you copy them ?
They must be in the "/pfm2/" directory.

No DFU capable USB device found

In what state is your PreenFM ?

Go in DFU mode from the Bootloader.

[squirts]

yup, saved in pfm2

Can you read and write preset with this USB drive in the Preen ?
What model is it exactly ?

here's what i got when adding the firmware in  dfu mode:
...
File downloaded successfully
..

So it worked. 

[squirts]

It's a samsung, but not sure which model as i'm in the office now.
But I could read presets with firmware 0.9 no problem (hadn't yet tried writing any as only got it yesterday).

Concerning the dfu mode write, no issue with the below?

No valid DFU suffix signature
Warning: File has no DFU suffix

[squirts]

Is it maybe worth erasing the USB and starting from scratch?

No problem... it's a gentle warning.
I should write that somewhere.

If it worked with 0.9 it will work with the 1.x series.
I don't know why the bootloader cannot read it.

[squirts]

really weird, ionly get intermittent access in DFU mode so i've unplugged all USB from my mac, so that the only thing left is the miniUSB (also used a new cable in case it was at fault) to CERB and run dfu-util and get this...

which should be 0483:df11, no?

it's a PITA as I now can't even roll back 1.02 boot loader which worked fine. is there a hard reset i can do to start from scratch?

I have no idea what you current version is (bootloader and firmware) and why you still use DFU.
But :

Yes it should be "0483:df11"... If you don't have it, what you see is another device.
"05ac" is the USB ID of apple. Any USB apple mouse you could unplug ?

DFU mode is independent from the bootloader... The bootloader just jumps to internal code of the microcontroller the actually takes care of DFU upload.
So it works exactly the same on ALL firmware.


With BootLoader 1.10, you don't need DFU.

Bootloader 1.10 : Press "Engine" to see the USB stick from your computer.
On your computer : Copy your bin to the  "/pfm2" directory of the device.
Reboot into PreenFM bootloader : Press "Op" to flash from the USB stick.

[squirts]

Sorry Xavier, I should've been clearer. Currently showing 1.10 bootloader, but no firmware. I get blank screen when i power up.

It doesn't behave like 1.10 bootloader though:   If I press Eng, the USB stick doesn't show on my computer.

I'd already copied the files onto the stick directly, but when I press OP, it doesn't flash from the stick
Flashing by MIDI doesn't work either... Which is why i was still trying by DFU

OK I see.
You didn't leave JMP3 on ?

Blank screen means you don't have a bootloader installed.
If you have a bootloader and no firmware, you see something like "PreenFM Bootloader OK but no firmware" on the LCD.

So you don't have any choice... DFU.
As you succesfully had it working in one of your previous messages (February 04, 2014, 10:10:20 AM), you just have to make it work on more time ;-)
And flash the bootloader.

[squirts]

No, JMP3 is definitely off, but I suspect the issue may have been with an incomplete or corrupted bootloader install.  Will try doing DFU from my work PC, might be less painful.

Thank for the help by the way, Xavier, it's much appreciated :-)

[Xavier]

As you don't have anymore the bootloader, the only way to enter DFU mode is put JMP3 on, and to switch on the PreenFM.

I run the cmds for install bootloader then overclocked firmware, but on removing jumper, reconnecting CERB and powering it back up, i still get the blank screen. I also still get the bootloader 1.10 prompt if i power up & press Op

so even on pc, it seems there's issue with getting the bootloader onto the preen, please see the line "aborting previous incomplete transfer"

or maybe that's normal, but the symptoms on the preen are still the same as before...

I'm trying to understand the state of your preenFM.
1. If you power up while a key is pressed, you can enter the bootloader.
2. If you power up without pressing a key, you have blank screen.

What i don't get if it's the bootloader works.
Can you enter each of the sub menu ?

[squirts]

1. & 2. Correct

Sub menu, if I press the following buttons, screen reads as follows

Eng: Bootloade v1.10 (USB drive not visible on PC)
OP1: USB Upgrade (but nothing further happens)
OP2: Sysex Upgrade, Erase firmware (it formats if I press erase, seems to accept the sysex message, but on reboot - no change, still blank screen)
MTX: !STM32F4 USB DFU!
