ST32L081 can not be programmed with firmware bigger than 128k with CubeProgrammer and UART-Bootloader.

Sorry, posted the wrong device before. Corrected that.

Maybe it is a device with only 128 kiB? You missed to tell the exact part number.

Oh, sorry. It is a STM32L081CZT6 with 192kiB

If you don't mind, please submit screenshot of the STM32CubeProgrammer.

And copy/Paste log window content including error messages if any.

Thank you for feedback, ticket entered.

I assumed you got latest CubeProgrammer v2.5.0.

VoWa

Yes, v2.5.0.

With the CLI it is the same. FW with <128kiB works, >128kiB does not.

Very weird, is that the "size" of the .HEX file on the computer, or the span of the content it describes internally?

Anything interesting in the .MAP file about the highest 0x08000000 region address?

No that is the size of the binay content of firmware itself. The .hex file on the comuper is about 3x bigger.

Can you clarify what you mean with "interesting" ? The firmware code iself is > 128 k. Programming via SWD interface is working properly.
