Is it possible to flash the internal memory of a blank STM32L496ZG through USB? The device has Boot0 pulled down to GND, but all the memory banks are blank, from the application note it's unclear whether the MCU executes the embedded system bootloade...

Resolved! How to activate bootloader is not consistent across documentation for STM32G051K8Tx (I do not know about other processors.)

AN2606 Rev 55 Page 241/432 says "... bootloader is activated by applying Pattern 6... Table 2"AN2606 page 27/432 Table 2, Pattern 6. Boot0(pin) = 1, nBoot1(bit) = 1, nBoot0_SW(bit) = 1Boot0(bit) = 0, nBoot1(bit) = 1, nBoot0_SW(bit) = 0Other two cases...

CANopenNode STM32 and FreeRTOS
