binman issue on ubuntu 20.04

[Belisko Marek]

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?

Thanks and BR,

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.
