STM32G070CB bootloader/DFU?

[sgordon777]

I am trying to figure out how to DFU a STM32G070CB, but finding the available documentation utterly useless..

According to this document : AN2606 "STM32 microcontroller system memory boot mode", my chip STM32G070 uses "Pattern 11":

#1. I know what the boot0 pin is (it's a pin on the chip). BUT what is "nboot0", What is "nboot1", What is "BOOT_LOCK", ??????????? These are described NOWHERE in in my 93 page STM32G datasheet, nowhere in the , or any other document I can find

#2: What are the four rows supposed to represent???

Hello @sgordon777 

nboot0", "nboot1",.. are option bits that are used for boot configuration.  "BOOT_LOCK" is not available for your MCU. as mentionned on the AN2606. The pattern 11 represent the bootloader activation patterns.

more démetails about that are available on the RM0454 specialy the chapter 2.5.

Best Regards.
