obsolete weakness #285


Weakness Breakdown


An obsolete weakness occurs when someone uses deprecated or obsolete functions when building a system. As a programming language evolves, some functions occasionally become obsolete.

Warning code(s):

This C routine is considered obsolete.

The highlighted line of code below is the trigger point of this particular Fedora 25 obsolete weakness.


 * issue the 'chip erase' command to the AVR device
static int stk500v2_chip_erase(PROGRAMMER * pgm, AVRPART * p)
