Update LoPy Firmware - Instructions if Pymakr is not working
-
@olddognewtricks Open up device manager and look at com ports. You should see one pop up when you plug in the device. Also after plugging in the board, hit the reset button before trying the updater.
.
Might need to update the FTDI drivers. -
@robert-hh Duh, sorry!
-
@ssmith Device Manager open. Plugged, un Plugged and Plugged in PyCom, no changes and also had it scan for new devices, no results.
I really appropriate you 2 trying to help. I'm trying to figure things out before I come to the forum. -
@olddognewtricks Try installing one of the windows drivers (32 or 64 bit, whatever you OS is) from this site: http://www.ftdichip.com/Drivers/VCP.htm.
And yes, just to ask the obvious: Are you sure that the USB cable works. Can you use it to transfer data to your phone or another device? -
It's definitely a com port issue. I tried to see if I could figure out how the 2 front USB ports were label in the device manager with a wild hair idea of inserting a Micro SD card in the expansion board to see if it would pop up but no luck, probably because the SD card isn't formatted. My only Com port listing is a NETGEAR application interface NMEA (Com 3)
-
@olddognewtricks Most likely an FTDI driver issue.
-
@olddognewtricks The SD card will never show up as a device, since the interface to the PC is a simple UART routed through an UART/USB bridge made by FTDI. Like said before, please
- check the cable
- check the driver
- check, is all jumpers are. But the device should be visible as COM port even if jumpers are missing.
-
@robert-hh I am usually really good at trouble shooting connections. I had tried 2 different USB cables and both powered up the board. The 3rd one pulled made it's sound when you plug in a USB into the slot and Com 4 appeared in the Com list.
-
@olddognewtricks Good. If the update still fails -
- did you have the jumper installed and did you push reset at Lopy after that?
- you could try to uncheck the 'high speed' option
- an Internet connection is required during update for fetching the firmware image.
-
Unplugged it one more time. Plugged it back in and hit the reset button. Then selected Com 4 and it worked. Thank you so much for your help. If I still had hair I would have pulled a few more strands out!
