Firmware reliability issue? #89

Open JohnDMcMaster opened 2 years ago

A few times we've observed what looks like some sort of reliability issue. Ex: yesterday tried to set VPP and it wasn't working. Re-init device and starts working again. Think there is some low level issue that might be causing memory corruption

Found something interesting in comlib:com_readline()

                printf(out_buf);

This has several red flags:

printf()'ing a format string supplied by an external user. Ex: typing %s into the terminal may cause weird results
Newline terminal is dicy, but probably ok
