Hi,
I'm trying to compile an older u-boot (2017.03) with Ubuntu 20.04. Machine is sunxi. COmpilation went fine but when binman assembles u-boot-sunxi-with-spl.bin it stuck somewhere. I've enabled python traces and it loops in forever:
subprocess.py(1668): if errpipe_data: cros_subprocess.py(94): if stdout_pty is not None: cros_subprocess.py(96): if stderr_pty is not None: cros_subprocess.py(100): if kwargs: command.py(73): while pipeline: command.py(95): if capture: command.py(97): last_pipe.CommunicateFilter(None)) --- modulename: cros_subprocess, funcname: CommunicateFilter cros_subprocess.py(144): read_set = [] cros_subprocess.py(145): write_set = [] cros_subprocess.py(146): stdout = None # Return cros_subprocess.py(147): stderr = None # Return cros_subprocess.py(149): if self.stdin: cros_subprocess.py(157): if self.stdout: cros_subprocess.py(158): read_set.append(self.stdout) cros_subprocess.py(159): stdout = [] cros_subprocess.py(160): if self.stderr and self.stderr != self.stdout: cros_subprocess.py(163): combined = [] cros_subprocess.py(165): input_offset = 0 cros_subprocess.py(166): while read_set or write_set: cros_subprocess.py(167): try: cros_subprocess.py(168): rlist, wlist, _ = select.select(read_set, write_set, [], 0.2) cros_subprocess.py(174): if not stay_alive: cros_subprocess.py(177): if self.stdin in wlist: cros_subprocess.py(188): if self.stdout in rlist: cros_subprocess.py(189): data = "" cros_subprocess.py(191): try: cros_subprocess.py(192): data = os.read(self.stdout.fileno(), 1024) cros_subprocess.py(195): if data == "": cros_subprocess.py(199): stdout.append(data) cros_subprocess.py(200): combined.append(data) cros_subprocess.py(201): if output: cros_subprocess.py(203): if self.stderr in rlist:
Any idea if there is some fix for that or idea where to look?
That code is processing output from a subprocess. It might be that the subprocess has hung. You can use -v5 to see what is being run, perhaps. Also -D might provide a traceback when you quit.
Thanks and BR,
