How to update the firmware?

[istone]

Hi,

I don't use Windows. Is there a means to flash the firmware without having to use the exe?

Thank you,
Chris

Hi Chris,

Yes there are other options, for example https://sourceforge.net/projects/bootstm32/

- What system do you use?
- Is your unit fully mounted box or a board (so you can access SWD connector?)
- Alternatively, are you familiar with some kind of DOS emulator, so you could run a simple command-line update utility instead?

Cheers,
Mario

Mario,

I am on a mac. My bit is mounted, but I can pull it out to do the update, and put a pigtail on it for the future.

That's great. Do you have ST-Link v2 (SWD adapter) too?

There surely is a way to upload firmware with or without it, via USB only - many other devices use the same or compatible architecture, for example modules from Mutable Instruments, ST Demo boards or various Arduino-compatible boards.

Does this guide apply to your system/version? You only need to install the st-util, then download the latest binary from here and flash it.

The alternative route without SWD adapter:

First install drivers, then upload binary using serial bootloader.

"Enabling the Bootloader" step is on Gecho achieved by switching off and pressing reset - you should see LEDs glowing in this pattern.

As not a Mac user, I cannot help you with more exact or verified steps, but hope this points you in the right direction.

That should be enough. Thank you.

I was able to flash the firmware using the serial drivers and the python script. Thank you for the help.

That's fantastic, happy to hear it worked for you!

I'm afraid you'll need to do it again as a new version went out this evening

No worries, it is easy enough to do. I’ll write up the steps and post them in case there are any other Mac users out there who need help.

That would be great, many thanks!

Man, I have a Mac and absolutely no skills in any of this flashing firmware business. I hate the thought of my Gecho leaving the nest but can i send it back to you Mario for the firmware update? Mark

Hi Mark, if you can't find a windows PC around then of course you can - just pack it well (I learned the hard way that 2 layers of bubble wrap won't do - so using bubble wrap + pizza cardboard I remember you wanted MIDI cables so I will be shipping a parcel to you anyway. Sorry for the trouble, I had a Mac developer's promise to port the updater utility but he seems too busy... :/

[Underglass]

If i download the gecho app on a windows PC then what kind of usb adaper do i use?

[Underglass]

worst case scenario what is the address to mail Gecho to for update/Midi cables? Thanks

[mario]

You only need a "mini-B" USB cable - it's the one commonly used with cameras or GPS devices:

I'll send you my address via email (it's still the same as from where your package arrived).
