FEZ Cerberus Firmware update


#1

I’m trying to update FEZ Cerberus and I have some difficulties:
If I follow instructions in:
http://docs.ghielectronics.com/hardware/legacy_products/gadgeteer/fez_cerberus.html
I can read: “To activate bootloader v2, set PA15 pin low.” Isn’t it PC1 instead ?
If I do this, I can see in Tera Term v2.0.4 which seems to be fine.
I send firmware, but after resetting, even if device manager can see a device, I can’t deploy to it.


#2

Today I was struggling to update FEZ Cerbuino Bee as well and found that connecting PA10 to GND enabled the serial bootloader mode. This should also work with Cerberus.


#3

Are you sure of PA10 ? Isn’t it PB10 ?


#4

This is really awkward :flushed:
I seem to have lost my way interpreting the Arduino style connectors on the Cerbuino. It is actually PC1 I’m using (as you already mentioned in your mail)
What I did in Tera Term was E(rase) and U(pload using Xmodem 1k) the Cerb Firmware v0.6.0.glb file.
I use Ms Visual Studio Community 2017 to build and start applications.

It works. It is PC1 !!!
Thanks a lot.


#6

The pins under the Boot Pins section are correct http://docs.ghielectronics.com/hardware/legacy_products/gadgeteer/fez_cerberus.html#the-boot-pins

We will fix the mention of PA15.
