Cannot upload bootloader in DFU mode #190

Closed benoit-girard closed 5 years ago

benoit-girard commented 5 years ago

Using Ubuntu 16.04, and arduino IDE 1.8.9, I get the following message when trying to upload the bootloader while in DFU mode :

Arduino: 1.8.9 (Linux), Board: "OpenCR Board, OpenCR Bootloader"

java.lang.NullPointerException
at cc.arduino.packages.uploaders.SerialUploader.burnBootloader(SerialUploader.java:329)
at processing.app.Editor.lambda$handleBurnBootloader$65(Editor.java:2384)
at java.lang.Thread.run(Thread.java:748)
Error while burning bootloader.

the lsusb tells me that the card in DFU mode is seen:

Hi, @benoit-girard

java.lang.NullPointerException at cc.arduino.packages.uploaders.SerialUploader.burnBootloader(SerialUploader.java:329) at processing.app.Editor.lambda$handleBurnBootloader$65(Editor.java:2384) at java.lang.Thread.run(Thread.java:748) Error while burning bootloader.

From the error log of Arduino, it seems that the dfu_util file updating the bootloader may not exist.

Please check if the file exists, or try reinstalling the OpenCR board package.

It is located in [The Arduino sketch folder you have set]/packages/OpenCR/tools
