When upload program to LGT IC, I got this error. I'm using IDE 1.8.14, LGT board 2.0 (with 1.07 it's ok to upload any program to LGT IC) win7 64bit Please help me out of this issue. Many thanks java.lang.NullPointerException at cc.arduino.packages.uploaders.SerialUploader.uploadUsingProgrammer(SerialUploader.java:295) at cc.arduino.packages.uploaders.SerialUploader.uploadUsingPreferences(SerialUploader.java:90) at cc.arduino.UploaderUtils.upload(UploaderUtils.java:77) at processing.app.SketchController.upload(SketchController.java:732) at processing.app.SketchController.exportApplet(SketchController.java:703) at processing.app.Editor$UploadHandler.run(Editor.java:2055) at java.lang.Thread.run(Thread.java:748)

Strange. On my PC at home, running Windows, the upload works without errors. Try to update your Arduino IDE because Arduino IDE 1.8.19 is the latest.

On the other hand, when I started Arduino IDE on my PC at work and waited until message "Updates available for some of your boards and libraries", the lgt8f boards disappeaed from menu and not listed as updatable board. This may have been due to the change in the name of the package path from "LGT8fx boards" to "lgt8fx".

I found a possibile solution with Google. https://forum.electro-smith.com/t/issues-when-uploading-to-arduino/238/4

Quote from the forum:

"I just fixed the wiki to properly mention using the ‘Upload’ button, and also included a note to not use the ‘Upload Using Programmer’ button."

This could mean you need to change the upload method.

This nullpointer error reminds me strongly of something that happened in Megatinycore after a version was withdrawn from the boards manager. You can read the issue here and it contains how to fix it.

@hmeijdam Thank you for the link of the article. When I updated my the lgt8fx package on my home PC the folder C:/Users/(your username)/AppData/Local/Arduino15/packages/LGT8fx Boards/hardware/avr became empty for some reason. So that was the reason of the error free uplodaing.

@manhabc please let us know if the upload went well after deleting the eralier package folder. LGT8fx Boards

@LaZsolt @hmeijdam Thank so much, it works well now. So if someone got error like me, just deleting all the earlier LGT folder in Arduino15
