Use Flash Loader with  a STM32L471 512K

Hi,

We are developed a proyect with teh MCU STM32L471. We have downloaded the appliacation Flash Loader V2.9  but don't have the file .STMap for this MCU.

We have a questions:

- Is there a newer version of the Flash Loader that includes the STM32L471?

- Is it possible for the ST community to provide us with the .stmap file for the STM32L471 or how to do it ourselves?

Thanks in advance

Best regards

Hi Javier,

I have the same question. Did you find an answer or a work around?

Thank you

ST needs to refresh these tools... Up vote the parent.

I agree. It would also be useful to have a description on how to create the .STmap files.

The STM32L471 512K uses the same die, with DEV_ID 0x0415

Try this .STMap

Thank you Clive. I get the same result with this .STMap file.

I did some more digging and it seems that most of the time the STM32L471 responds with 0xC0 0x79 in response to the initialize byte (0x7F) sent via the UART. The UART protocol show that it should only respond with 0x79 to the initial byte of 0x7F. I have managed to get it to work more reliably at 9600 baud but at times the mystery 0xC0 byte shows up as the first response.

It could be bus noise. Make sure to use even parity, ie 9600 8E1

I had the same result on a Nucleo board with a STM32L476...the mystery continues.

I should note, that I have this working on several other HW configurations with a STM32L432 or STM32L496.

Hello,

I recommend you to use the new STM32CubeProgrammer software

tool delivers device-programming and firmware upgrade for STM32

microcontrollers following the instruction in the User Manual and System requirements:

Hello,

Sorry to respond so late.

Thanks for your answers.

Now I am using the STMCube programer and it works fine, but I would like to know if there is any way to configure the status of the peripherals and GPIOs in bootloader mode?
