I use Arduino IDE with Ubuntu 16.04.
Everything used to work. I uploaded a firmware a few times. But once it just started returning:
Build options changed, rebuilding all Sketch uses 301454 bytes (14%) of program storage space. Maximum is 2097152 bytes. /home/alexeyisme/.arduino15/packages/RAK/tools/ameba_tools/1.0.9/upload_dap_linux /home/alexeyisme/.arduino15/packages/RAK/tools/ameba_tools/1.0.9/ram_all.bin uploading... cp "/home/alexeyisme/.arduino15/packages/RAK/tools/ameba_tools/1.0.9/ram_all.bin" /media/alexeyisme/MBED/;sync upload finish
It says upload finish, but dash button firmware is not updated. I think I just don't see what I do wrong.
