Segmentation fault in libdwf

[Someone]

Hello,

I want to read UART data with a Digital Discovery. When I change the Digital_Uart_RX.py demo to use a rate of 8 MHz (or 10 MHz) it segfaults:

#0  0x00007f7a3a5558e9 in iFDwfDigitalInStatusData2(DINSTDVC*, void*, int, int) () from /lib/libdwf.so
#1  0x00007f7a3a563c4e in FDwfDigitalUartRx () from /lib/libdwf.so

I can't say if this is dependent on the data on the line or not. Is there a limitation on UART rates? I hope this can be reproduced.

Hi @Someone

Which software version are you using ?

I've just tested WF 3.19.5 and 3.19.29 with DD receiving 80MB of text at 10MHz.

I'm using the newest 3.19.29 on Linux. The segfault is reliable either with the Python demo or my own code. I could give a more useful backtrace if you happen to have a library with debug symbols.

Hi @Someone

Thank you. I've managed to reproduce it under Linux.
