Hardware and layout

This section describes STM8A-DISCOVERY hardware and layout which can be broken

down into common resources used both in STM8AF and STM8AL boards and the special

features belonging to each of them.

4.1

STM8A-DISCOVERY common resources

4.1.1

Embedded ST-LINK/V2

The ST-LINK/V2 programming and debugging tool is integrated both in STM8AF and

STM8AL boards. The embedded ST-LINK/V2 can be used to program/debug the MCU on

the board and supports SWIM for STM8 devices.

The ST-LINK/V2 must be connected with the dual type A to mini-B USB cable provided in

the blister.

Caution:

First connect the dual type A on the PC side (both type A connectors must be plugged in)

then connect the mini-B USB to the board (STM8AF or STM8AL boards).

For programming or debugging the STM8A-DISCOVERY, the PC can be either connected to

the mini-B USB connector of the STM8AF or STM8AL board.

The connection on both mini-B usb of the STM8AF and STM8AL boards is not supported.

This operation can damage the boards.

For information about debugging and programming features refer to user manual UM1075

(ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32) which describes in

detail all the ST-LINK/V2 features.
