STM32L4 devices boot to system memory after flashing with v2.23.0
Using an STM32L432KC Nucleo, I observed that STM32CubeProgrammer v2.23.0 toggles FLASH_SR.PEMPTY when it flashes an image of an odd number of 2 KiB pages to the L432KC. The board then boots into the ROM bootloader instead of the present application in flash. (I used the programmer through zephyr’s west flash on Ubuntu.)
