2) nuttx.hex - This is an Intel Hex format file. This is controlled by
the setting CONFIG_INTELHEX_BINARY in the .config file.
The PICkit tool wants an Intel Hex format file to burn into FLASH.
However, there are two problems with the generated nutt.ihx:
1) The tool expects Intel Hex format files to be named *.hex. This
is not a significant issue. However, just renaming the file to
nuttx.hex is *not* sufficient. There is another problem:
2) The tool expects the nuttx.hex file to contain physical addresses.
But the nuttx.ihx file generated from the top-level make will have
address in the KSEG0 and KSEG1 regions.

---------------
There is a simple tool in the configs/sure-pic32mx/tools directory
that can be used to solve both issues with the nuttx.ihx file. But,
that can be used to solve both issues with the nuttx.hex file. But,
first, you must build the the tools:
cd configs/sure-pic32mx/tools
make
Now you will have an excecutable file call mkpichex (or mkpichex.exe on
Cygwin). This program will take the nutt.ihx file as an input, it will
Cygwin). This program will take the nutt.hex file as an input, it will
convert all of the KSEG0 and KSEG1 addresses to physical address, and
it will write the modified file as nuttx.hex.
it will write the modified file, replacing the original nuttx.hex.
To use this file, you need to do the following things:
. ./setenv.sh # Source setenv.sh. Among other this, this script
# will add configs/sure-pic32mx/tools to your
# PATH variable
make # Build nuttx and nuttx.ihx
mkpichex $PWD # Convert nuttx.ihx to nuttx.hex. $PWD is the path
make # Build nuttx and nuttx.hex
mkpichex $PWD # Convert addresses in nuttx.hex. $PWD is the path
# to the top-level build directory. It is the only
# required input to mkpichex.
