How do i boot from one of two locations on the STM32L072RBT6? I

[HElHa]

have a default location X. If want to update the code, i download it to location Y and expect the STM32 to start at location Y after reboot. However, the routine keeps rebooting from X. what am i missing?

Which tool should I use? I used winhex for merging 3 hex files - bootloader, app1, app2.

Winhex does not display data as you showed.

This is my hex file which is opened in STM32CubeProgrammer.

Could you please let me know where the last line is?

Thank you.

They are in ASCII, use notepad or some text editor
