Hello everyone here, I have a STM32L43x µC and I wish to read the Memory size when I am in Bootloader mode. I tried using the function Read Memory command to read the register at address (Base address: 0x1FFF 75E0) which contains the Memory size. Unfortunately this is not working. Can someone give me a quick hint on how to read the Memory address in bootloader mode? Thanks in advance

Only read unprotected areas can be read out in boot mode. Try reading user flash code at 0x08000000 . If it works , 0x1FFF 75E0) must be having read protection active on it.
