Can't seem to update my Fomu

Windows10

As I got it, dfu-util -l says

dfu-util 0.9

I see no rainbow colours, but when I run dfu-utl -l again:

All seems good. However, if I unplug and then put back into the USB, it seems to have reverted

Any idea what is going on?

And if I unplug and plug it back in, goes back to v1.9.1

[fancellu]

Is this a known issue?

im-tomu/fomu-toolchain@4315d88

[fancellu]

BTW, dfu-util -D micropython-fomu.dfu works fine, I can connect to the virtual com port and do some micropython.

However it still doesn't survive unplugging/plugging, goes back to 1.9.1

[fancellu]

Also, I try to use IceStudio and get this

dfu-util -d 1209:5bf0 -D hardware.bin
dfu-util 0.10

Verilog is fine with APIO or the fomu toolchain

Aha, a known issue.

I updated to 2.02 (saw the rainbow), persisted on reset

Then moved to 2.03 just fine

We should probably put a warning note in the documentation around this somewhere?

@xobs - What do you think?
