I’m assuming it’s the EMX device that the other thread is about.
What devices are visible in Device Manager, that it’s complaining about? Can you boot it back into serial bootloader mode so the COM port appears? Then, step through the update with TeraTerm.
There was an EMX driver issue early in Win8 then Win10 days, was there not? Bootloader update reliably works under Win7 though, were any of the multiple machines you tried running Win7 by any chance?
Yes, this is correct. It’s same EMX as in other thread :))
There are no USB devices visible.
There is some sort of COM1 device, but it’s there even when USB is not plugged.
I think what happened is that I tried to update TineBoot with version 4.2.5.0, while firmware was selected automatically for 4.2.11.1…
And that’s why it failed in the first place.
But I don’t think I can actually brick the board completely this way ?
When you say booting with serial loader is by shorting pins (instruction appears with TinyBoot update) ?
I tried that and that’s when I get “can’t communicate with serial device” error…(window)
I use Win7, so I doubt that problem is with driver, but I can try to reinstall it… ?
