devicetree.bbclass: Combine stderr into stdout to see actual dtc error
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 Signed-off-by: Jaewon Lee <jaewon.lee@xilinx.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> Signed-off-by: Armin Kuster <akuster808@gmail.com>
