STM32CubeProgrammer Failure on STM32L4 with Error: Operation exceeds memory limits

[rkaushal]

Hi,

I am trying to flash MCU firmware on my STM32L4A6VGTx MCU in bootloader mode over UART using cube programmer v2.17.0. I tried through UI and command line but in both the cases it if failing with error- Operation exceeds memory limits.

Please refer output below and screen shot as well as logs attached.

I got to know there are some changes in address ranges in MCU database config files like the one provided on link- https://community.st.com/t5/stm32cubeprogrammer-mcus/stm32cubeprogrammer-failure/td-p/636609. However, this does not apply to out STM32L4A6 board.

Please provide a similar fix for my board referring to STM32_Prog_DB_0x461.xml.

Looking forward for the early resolution of same.

Thanks

Thank you so much Imen for prompt response.

Hello @rkaushal 

Issue is not reproduced, and the test is worked fine with the latest release of STM32CubeProgrammer v2.18.

Could you please test with this release (STM32CubeProgrammer v2.18), then keep me informed about your updates.

Below the traces with STM32CubeProgrammer v2.17 and STM32CubeProgrammer v2.18:

Hi Imen,

This sounds great. Let me connect with IT to have update of latest 2.18 CubeProgrammer and try out this. I will share an update on this on Monday.
