|
# | Generic C-compiler | Yes | Pre-processing of devicetree |

# Path to C compiler.

#
|
|
# 'GPERF'
|
|
# Path to gperf.
|
|
# Set to 'GPERF-NOTFOUND' if gperf was not found.
|
|

|
|
# 'OPENOCD'
|
|
# Path to openocd.
|
|
# Set to 'OPENOCD-NOTFOUND' if openocd was not found.
|
|

|
|
# 'BOSSAC'
|
|
# Path to bossac.
|
|
# Set to 'BOSSAC-NOTFOUND' if bossac was not found.
|

# 'IMGTOOL'
|
|
# Path to imgtool.
