Flash hex file to stm32f412 with stlink using stm32cubeprogrammer

[Vaishnavi]

Tried flashing stm32f412 custom controller using uart but facing error while going to boot mode.

Tried flashing using stlink, connected but failed to erase memory and application exiting automatically.

Hello @Vaishnavi and welcome to the Community,

Ensure that both the ST-Link firmware and STM32CubeProgrammer are updated to the latest versions.

Check the power supply to the board and check the jumper settings.

Try select the "Connect Under Reset" mode in STM32CubeProgrammer and erase the whole MCU.

Hope these steps and tips help you resolve your issue.

Hi @Imen.D 

Stlink and cubeprogrammer are using updated version only

Connected under reset only, its connecting but unable to erase whole mcu

What's going on with the VCAP pin(s) ?

Do you see 1.25v there?

Have you placed 4.7uF total capacitance on them? And not omitted or placed wrong values?

I thought the UART part was addressed in your other thread - marked as solved:

https://community.st.com/t5/stm32cubeprogrammer-mcus/flash-hex-file-to-stm32f412-with-uart-or-stlink-using/td-p/729115

So is this thread just about the ST-Link part?

As noted, you need to show your schematics:

A good, clear photograph could also help

Modified the post to focus on STLINK.

The system bootloader usage has been answered in this thred: https://community.st.com/t5/stm32cubeprogrammer-mcus/flash-hex-file-to-stm32f412-with-uart-using-stm32cubeprogrammer/td-p/729115
