Previously the subprocess command to run dtc was not properly displaying
the error on console. Combining stderr into stdout for the dtc subprocess
so the actual error can be seen on console without having to open the
do_compile log.
For example, previously on a dtc error, just the following stack trace
and dtc command was being shown on console:
File: 'exec_python_func() autogenerated', lineno: 2, function: <module>
0001:
*** 0002:devicetree_do_compile(d)
0003:
File:
function: devicetree_do_compile
0127: if not(os.path.isfile(dtspath)) or
not(dts.endswith(".dts") or devicetree_source_is_overlay(dtspath)):
0128: continue # skip non-.dts files and non-overlay
files
0129: except:
0130: continue # skip if can't determine if overlay
*** 0131: devicetree_compile(dtspath, includes, d)
...
Exception: subprocess.CalledProcessError: Command '['dtc', '-R', '8',
'-b', '0', '-p', '0x1000', '-i', '${INCLUDES}, '-o', 'system-top.dtb',
'-I', 'dts', '-O', 'dtb', 'system-top.dts.pp']' returned non-zero exit
status 1
with this patch, the actual error from the dtc command will be appended
like the following:
Subprocess output:
Error: Label or path not found
FATAL ERROR: Syntax error parsing input tree

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
