Hi, I have two HTCC-AB02A. One works fine. The other started showing nonsense characters in the Arduino IDE Serial Monitor before becoming completely unresponsive. It does not upload sketches:
Initialising bootloader. Unhandled error: Timed out waiting for Bootloader response.
Note that the device normally goes into programming mode automatically, I don’t have to press the RST/USR buttons. The IDE’s Tools | Burn Bootloader menu option don’t do anything either:
Error while burning bootloader java.lang.NullPointerException at cc.arduino.packages.uploaders.SerialUploader.burnBootloader(SerialUploader.java:329) at processing.app.Editor.lambda$handleBurnBootloader$61(Editor.java:2379) at java.lang.Thread.run(Thread.java:748) Error while burning bootloader.
I’ve been using it with an ADXL345 accelerometer. Is this Cubecell dead? Is there a way to get the bootloader on there, if that’s the problem?
Device information (same for both boards, the working and non-working one):
BN: Unknown board VID: 10C4 PID: EA60 SN: Upload any sketch to obtain it
