Supporting toolchains (not exhaustive)

Table 7 gives a list of the first toolchain version supporting the STLINK-V3MODS and

STLINK-V3MINI products.

Note:

Some of the very first toolchain versions supporting the STLINK-V3MODS and STLINK-

V3MINI (in runtime) might not install the complete USB driver for STLINK-V3MODS and

STLINK-V3MINI (especially the STLINK-V3MODS bridge USB interface description might

miss). In that case, either use a more recent version of the toolchain, or update the STLINK-

10.2

Drivers and firmware upgrade

The STLINK-V3MODS and STLINK-V3MINI require drivers to be installed on Windows, and

embed a firmware which needs to be updated from time to time in order to benefit from new

functionality or corrections. Refer to the Overview of ST-LINK derivatives technical note

(TN1235) for details.

10.3

STLINK-V3MODS and STLINK-V3MINI frequency selection

The STLINK-V3MODS and STLINK-V3MINI run internally at three different frequencies:

•

high-performance frequency

•

standard frequency, compromising between performance and consumption

•

low-consumption frequency

By default, the STLINK-V3MODS and STLINK-V3MINI start in high-performance frequency.

It is the responsibility of the toolchain provider to propose or not the frequency selection at

user's level.

10.4

Mass storage interface

The STLINK-V3MODS and STLINK-V3MINI implement a virtual mass storage interface

allowing the programming of an STM32 target flash memory with drag-and-drop action of a

binary file from a file explorer. This ability requires the STLINK-V3MODS and STLINK-
