Hello, I am using STM32L021F4 on a custom board and I am attempting to flash firmware using the FLASHER-STM32 software via the internal bootloader and a FT232RL USB/UART serial bridge. I can connect to the MCU and the flash loader says the MCU is readable, but on the next screen there is nothing in the Target drop down menu.
From the datasheet, this MCU has a 16 kb flash, and after looking in the flash loader map directory, there doesn't seem to be an STM32L0 map for 16 kb flash. Is there anything I can do to get bootloader flash programming up and running?
