Dear community,I am playing with the STM32L082CZ and IAR, and I noticed that the FLASH_OPTR register is not displayed in the registers. But at the same address there is the OBR register (but the bit description is different from the datasheet)I am us...

Dear all,I am requesting your help to understand well how the dual bank mechanism works before I start writing the firmware:I will use the internal bootloader to allow me to start from Bank1 or Bank2. Bank1 will store the factory firmware, and Bank2 ...

I answer to myself to help people that could have the same question. The banks remains swapped even after a power cycle since the BFB2 bit is in the non volatile memory, but it is always possible to know which bank is used.

Hi TDK,Thank you for your answers.So, if I want to use the ROM bootloader, I must check carefully that the bank 2 contains a valid code before rebooting on it. My idea to reduce the risk would be to reset BFB2 at the beginning of each firmware to reb...

Hi,So you recommend to always start on bank 1 with the production firmware and to jump to bank 2 if valid ?Why you do not want to use the system ROM ? It looks like it does exactly what I would like to do, so if I can avoid to rewrite it. A very impo...
