Development tool adaptations

The changes in the device hardware have impacted the development tools. Following the

change of device identifier (DEV_ID) and some peripherals changes with the addition of

new features, it has been necessary to upgrade the development tools as detailed hereafter.

1.

DEV_ID changes:

In STM32L100x6/8/B and STM32L15xx6/8/B devices, DEV_ID=0x416

In STM32L100x6/8/B-A and STM32L15xx6/8/B-A devices, DEV_ID=0x429

If the software or programming tool is using DEV_ID[11:0] field (in DBGMCU_IDCODE

register) then the relevant changes must be applied in the software or tool.

2.

Changes in the development tool configurations:

a)

IAR - install the latest version or apply the patch provided by ST support team to

support the new device, and change the device type in the configuration.

b)

Keil - install the latest version that supports the new device, change the device

type in the configuration, and change the ST link programming algorithm.

c)

Others - install the latest version that supports the new device, and change the

device type in the configuration.

3.

STM32L1xx standard peripherals library update:

STM32L15xx6/8/B-A and STM32L100x6/8/B devices are supported in the latest

version of STM32L1xx standard peripherals library. Make sure to use the latest version

of STM32L1xx standard peripherals library to use the new peripheral features.

a)

The STM32L15xx6/8/B-A and STM32L100x6/8/B-A devices are supported from

STM32L1xx standard peripheral library version 1.2.0 available from

www.st.com/stm32.

b)

Define the macro STM32L1XX_MD and use it in the project

startup_stm32l1xx_md.s file.

c)

Rebuild the existing project with the new library so it can be run on

STM32L15xx6/8/B-A or STM32L100x6/8/B-A device.

4.

Programming tools adaptation:

In the programming tool configurations (for example ST link with the related software)

the device type must be changed to correctly program the new STM32L15xx6/8/B-A or

STM32L100x6/8/B-A device.

Use the latest ST Visual Programmer (STVP) or the latest ST-link utility which support

the new devices (both are available at www.st.com/stm32).
