[Fixed] Flashing the Bootloader in a Mac with Mavericks

<< < (3/13) > >>

Varthdader:
Thanks for all the patience!

Where should I have the respective .bin files? Because I tried this and the terminal says it can´t find the files.

Xavier:
The link to the last firmware is at the top right of this page.
Direct download to the last firmware :
https://dl.dropboxusercontent.com/u/41654198/preenfm2/firmwares/pfm2_0.9n.zip
Unzip the file.

In the terminal, move to the directory where you extracted the files (using cd command).
Run the dfu-util commands from this directory.

Varthdader:
Ok, now this feels embarrassing, but I have close to zero terminal skills...

I managed to move to the appropriate directory, and flashed both boot loader and over clocked firmware!

My PreenFM2 now boots into the new firmware!

But, if I plug the usb cable to my Mac, I should be seeing the usb stick appear as removable media right?

I see no such thing, am I missing something?

Thanks!

Xavier:

Congrats it's done  ;)

To enter bootloader, you must press one of the button while powering on the PreenFM.
Release the button when you see "BootLoader v1.10" on the LCD.
You have then several  choices :

1. Press "Eng"  and your USB stick will appear on your computer after a couple of second.
You can then copy the future firmware on the USB stick that way (copy them in the '/pfm2/' firmware).

2. Press 'Op' and you can select one of the firmware from the USB stick to flash.

So you won't have never agin to fight with dfu-util :-)

Varthdader:
Super!

All is wonderful now!

I can see the usb stick in my Mac and also the beautiful orange led on the pcb finally lighted telling me I soldered it properly! :D

Thank you Xavier and also 6581punk for all the help!
