Longan Nano PlatformIO issues

Using and setting up PlatformIO.

I am trying to upload the demo longan LED blink program. I can build the project but I can’t upload it, I keep getting the error:

What does Invalid DFU suffix signature mean?

Any thoughts? Thanks.

Can you see the longan board in the device manager? Is there a libusb driver for longan?

If you use linux, try adding a udev rule, or set the access permissions of the longan device to 777.

@BigBits Thanks for the help. I am using an Ubuntu flavor called Pop_OS!.

  1. Are you referring to PlatformIO’s Devices tab? If so then I don’t see it. However, if I plug in the JTAG debugger then I can see the debugger.

  2. Ironically I do have libusb installed. I had to compile and install the latest because I am programming in Go to access Adafruit’s FTDI breakout board. Also, I didn’t know there was a libusb requirement for the Longan–I guess I met it by happenstance ;-).

  3. I am aware of udev rules and have several for FPGAs and one for PlatformIO, but I didn’t know Longan’s dependency. So I added a udev rule that matched dmesg’s output:ATTR{idProduct}=="0189", ATTR{idVendor}=="28e9", MODE="0666". But I still don’t see it listed as a device by PlatformIO.

dmesg says:

And as mentioned previously, I can’t upload because of some DFU error. :thinking:

Good news. It works ! :partying_face:

Re-triggering udev rules didn’t work so well. I needed to do a full reboot, and by full-reboot I mean I had to literally reboot the motherboard. I have a system76 machine and it has both a soft-reboot and hard-reboot–it took a hard-reboot.

I was able to finally upload the blink example. Yeah! :nerd_face:
