2.4 Programming and debug
The microcontroller in the discovery board can be programmed and debugged using two
methods
(b)
:
Standard JTAG connector (male 2 x 7 100 mil - 90°)
USB port with integrated debugger.
A further configuration in addition to the previous configurations allows configuring the board
as a standalone PLS adapter; in this case, the JTAG connector has to be connected to the
target board adding a passive male-female 2 x 7 pin adaptor.
