Error when uploading code to board

[Marzogh]

Hi guys, I've been trying to see if I can make my SPIFlash library compatible with ExploreM3.
The code compiles fine, but when I try to upload it to the board I'm greeted with a

java.io.IOException: Cannot run program "/Users/prajwal/Library/Arduino15/packages/ExploreM3/hardware/Explore-M3/1.0.0/tools/macosx/macosx/exploreM3_upload": error=2, No such file or directory

Can you help me figure this out?

I can confirm that the file exists and I have made sure that the the tools folder has been chmod 777 'd.

I thought I'd try and re-install the Arduino core to see if would fix the problem. Now the code does not compile at all and fails with the error

/Users/prajwal/Library/Arduino15/packages/ExploreM3/hardware/Explore-M3/1.0.0/libraries/SPI/SPI.h:32:21: fatal error: spiIntr.h: No such file or directory
 #include "spiIntr.h"
                     ^
compilation terminated.

Added spiIntr.c and spiIntr.h files. Try compiling now.
