Segfault on BBB AM3358 Debian 10.3 2020-04-06

[davidgood1]

gdb shows the following output:
0x00401480 in BBBIO_sys_pinmux_check (port=1, pin=16, Cflag=7) at ./BBBio_lib/BBBiolib.c:628

In function BBBIO_sys_pinmux_check, dereferencing this pointer causes the crash:

(lines 627 and 628)
reg =(void *)CM_ptr + ExpHeader_MODE0[port][pin] ;
reg_value = *reg ;

Any ideas?

Did you get this segfault in your own program? Or what where you trying to do? I have been using this lib for some projects now and never had it segfault outside my own errors.
