Openmoko firmware upgrade , no jumper to enter DFU mode or button

[pergolafabio]

Hi,

hope someone can help me, i have purchased an canable, seems its an Openmoko, i want to change firmware on it, was testing it like below, but it gives errors? As you can see in screenshot, i dont have a jumper to enter DFU mode? nor do i have a button on it? Anyone seen this before?

What's the output of lsusb|grep -i open?

[marckleinebudde]

Use make flash-candleLight_fw to flash the firmware.

Edit: For a canable device use make flash-canable_fw.

If it's a canable device better flash the canable firmware: make flash-canable_fw.

sorry, indeed new to this, but according to canable site, i also need to set the jumper or press the button, but i dont see any of those?

[marckleinebudde]

It should work without an extra jumper.

[pergolafabio]

ah ok, just unclear how to flash? i have downloaded the canable_fw file, as you can see? but the command gives an error?

I have a sample here of that board. It has a pair of BOOT0 pins labelled on the rear. I have not reflashed this unit.

yeah, mine looks the same indeed, it just named 303canable3 instead

i need to shortwire those pins then ? buts its a plastic box :-)

[marckleinebudde]

open the plastic box, or use a solder iron to make some holes :)

[pergolafabio]

omg, why did they make it so difficult then

[pergolafabio]

Thnx for all support guys!! appreciated

If anyone have some good tips how i can short ciruit thos 2 pins when i remove the plastisc, feel free to show first them i gonna do this! :-)

[marckleinebudde]

Use some metal tweezers or unfold a paper clip.

[pergolafabio]

just last question, if i use a tweezer or clip, do i need to connect it the while time? Or is is enough to use the tweezer, then plugin usb , at that point , can i detach the tweezer?

[marckleinebudde]

Unplug USB, short pins, plug USB, then you can remove the tweezers/paperclip.

thnx for all support guys!
