When I am trying to upload a Arduino sketch from External IDE in UDOO NEO I am getting this erore: arm-none-eabi-gcc: no such file or directory If anyone is familiar with this please help me. Thanks.
On what kind of PC is your External IDE running (Windows, Linux?) When do you get this error, during compile on you of after that when sending/uploading to the Neo with UDOO FOTA ? see the error log.
Then your install of the IDE is not correct. Did you see this: https://www.stm32duino.com/viewtopic.php?t=3510
