Instruction: In mbed-os\targets\TARGET_STM folder Add the new device (if not already present) in the mbed_rtx.h file in the correct memory area.

Which of the following is the correct memory area for STM32L452RE-P board (and then for INITIAL_SP variable) ?

0x20002000UL 0x20003000UL 0x20004000UL 0x20005000UL 0x20008000UL 0x2000A000UL 0x20010000UL 0x20014000UL 0x20018000UL 0x20020000UL 0x20030000UL 0x20040000UL 0x20050000UL 0x20080000UL

??

Thank you in advance.

These values correspond to the RAM top address.

The STM32L152RE has 80KB of RAM which is equal to 0x14000 in hexadecimal. The top address is then equal to 0x20014000.

The STM32L152RE_P device is identical to the STM32L152RE in term of FLASH/RAM.

You should declare the STM32L152RE MCU in the targets.json file (in extra_labels_add and device_name fields). This way you will have nothing to change in the mbed_rtx.h file.

Hi,

Thank you for your answer.

I have solved this problem, but now I'm having others (log below). By the way, STM32L452RE-P has 160Kbytes of SRAM and 512 Kbytes of Flash Memory, so it's different to the STM32L152RE one, but I got the idea, thank you again. This kind of platform should be plug & play, as Arduino, I'm really disappointed that some models are supported and some others not, it's really a shame.

If I continue doing this on my own, I will never stop having errors. I only wanted to program something simple on this board, and not having to read all the datasheet to became a ARM processor expert :( It's really a shame.

Hello everyone,

I have continue trying to reconstruct the target NUCLEO_L452RE_P (STM32L452RE-P) for the mbed environment, and I get the following.

After installing 6 GB when trying with different environments, compilers, etc, I have reconstructed the correct files for this microprocessor version, taking it from STMCubeMX. Only after that I can compile almost all my bllink project using mbed environment, but the only file I continue having problems is "PeripheralPins.c" file provided by ARM Mbed compiler.

I'm having the following Errors (If someone could help, I can finish it and publish it on mbed site, for everyone having access to it like with the rest of the models) :

(I have cut the errors here)

For the moment I decide to use the combination of "Atollic TrueSTUDIO for STM32" + "STMCubreMX" who is working very well, even using debug.

Thank you in advance.
