for a few days now, i have a very confusing problem.
i wanted to play around with the fpga and used the usb blaster sketch to program the fpga via quartus prime. this worked perfectly for a few weeks.
now when i connect the vidor to my pc to program a different sketch to it, the vidor doesnt connect to the pc. the arduino ide cant find it on any port and it doesnt show up in the device manager from windows.
and when i open the ide after i connected my vidor all my installed boards in the ide are deleted and i am unable to install them again, because when i open the boards manager it shows "http://downloads.arduino.cc/package_index.json file signature verification failed. file ignored"
hopefully anyone is able to help me
Have you tried putting the Vidor board into bootloader mode by double pressing the Rest button on the top of the board? The COM port will more than likely change when you do this.
Also, this error you are seeing seems to pop up for various reasons. It could have been a glitch in the network or something on your system is corrupted or even a proxy setting in the Arduino IDE.

Has anyone programmed XMC microcontroller by Infineon Technologies using Arduino… IDE?
I tried as per the steps given in the GitHub repo of Infineon. Below is the link of the same:
[https://github.com/Infineon/XMC-for-Arduino/wiki/Implementation-in-Arduino-IDE](url)
After I copied the .json url in the preferences, I am getting following error:
http://downloads.arduino.cc/packages/package_index.json file signature verification failed. File ignored.
Index error: could not find referenced tool name=arm-none-eabi-gcc version=4.8.3-2014q1 packager=arduino

What can be a possible solution for it? I am running Arduino IDE 1.8.5 on Windows 10. Is this has anything to do with it?

We have had four reports of this error on the forum in the last two days. The us… ual trick of clearing out the data folder and trying again didn't work for any of them. One of the users, Cheetor, provided the package_index.json and package_index.json.sig files they get from https://downloads.arduino.cc/packages/package_index.json and https://downloads.arduino.cc/packages/package_index.json.sig:
- https://forum.arduino.cc/index.php?topic=621811.msg4212477#msg4212477
- https://forum.arduino.cc/index.php?action=dlattach;topic=621811.0;attach=312913
I compared these to the files I download from the same URLs and found that their package_index.json file was missing the entries for Arduino SAMD Boards 1.8.1 and avrdude 6.3.0-arduino17, but no differences other than that. The checksum of their .sig file matches mine.
Cheetor is in New Zealand and one of the other reporting users (DavidBMason) is as well. The other two haven't provided their location. The problem stopped occurring for DavidBMason before I could get the bad package_index.json and package_index.json.sig files from them:
https://forum.arduino.cc/index.php?topic=621637.msg4212584#msg4212584
My hypothesis is that there was a recent update to package_index.json but the new .json file didn't make it to a server that provides the files to people in NZ. However, the new .sig file did make it to that server. So they are getting the old .json file but the new .sig file, thus the signature verification. Further evidence of this is that when Cheetor used TOR with an exit node in the USA they got the new version of package_index.json:
https://forum.arduino.cc/index.php?topic=621811.msg4212512#msg4212512
It would be nice if there was some way to make sure that the .json and .sig files will always hit the servers at the same time. I suspect this delay of days on the .json file is a rare glitch but if we regularly have a delay of even minutes that still is going to cause problems for people, more so because of https://github.com/arduino/Arduino/issues/8936.
