DFU error GIGA R1 Wifi

I tried to upload a sketch to my giga board today and received a DFU error similar to many other users. The posts I read suggested adding a rules file containing "SUBSYSTEMS==”usb”, ATTRS{idVendor}==”2341″, MODE:=”0666″" to /etc/udev/rules.d but it does not seem to have any effect even after reboot.

Any suggestions would be greatly appreciated.

UPDATE: I was able to execute the script from https://support.arduino.cc/hc/en-us/articles/9005041052444-Fix-udev-rules-on-Linux#mbed-os and it seems to be working.

Hi @richpaul6806. Please post the full and exact text of the error message.

no problem @ptillisch, I didnt post it initially because so many others have posted the same error and it is well documented but if you think it will help...

Sketch uses 109480 bytes (5%) of program storage space. Maximum is 1966080 bytes.
Global variables use 47528 bytes (9%) of dynamic memory, leaving 476096 bytes for local variables. Maximum is 523624 bytes.
An error occurred while uploading the sketch

@ptillisch I was able to get it to work. Updated my original post with solution.

Thank you very much for sharing the solution of dfu problems for Arduino GIGA R1 boards. This resolved a difficult situation that had already been going on for several days.
