SWD module

Prerequisites

api = HardsploitAPI()
crossvalue = [24, 25, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 0,

api.set_cross_wiring(crossvalue)

The code initializes the Hardsploit API and sets the cross-wiring configuration. It is required for the SWD communication.

"set_cross_wiring()" is used to configure the physical and logical connections between Hardsploit's components.

SWD Class
