Development tool adaptations

When migrating from STM32L15/6xxD to STM32L15/6xxE some changes in the

development tools are necessary. 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 STM32L15/6xxD devices, DEV_ID = 0x436

In STM32L15/6xxE devices, DEV_ID = 0x437

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 STM32L15/6xxE device, and change the device type in the

configuration.

b)

Keil - install the latest version that supports the STM32L15/6xxE device, change

the device type in the configuration, and change the ST-LINK programming

algorithm.

c)

Others - install the latest version that supports the STM32L15/6xxE device, and

change the device type in the configuration.

3.

STM32L1xx standard peripherals library update:

STM32L15/6xxE 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 STM32L15/6xxE device features.

a)

Define the macro STM32L1XX_XL and use in the project the

startup_stm32l1xx_xl.s file.

b)

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

STM32L15/6xxE devices.

4.

Programming tool adaptations:

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

the device type must be changed to correctly program the new STM32L15/6xxE

devices.

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

the STM32L15/6xxE devices (both are available at www.st.com/stm32).
