Hi,
I have STM32F030 which is connected to STM32L082 with UART (Rx/Tx), RESET and BOOT0 line. When needed STM32F030 is able to restart STM32L082, run ROM Bootloader, erase and program flash.
But when I have clean STM32L082, empty flash on it on production, STM32F030 has a problem with restart and run main program for STM32L082. To run it, it needs power reset.
I've read about OBL_LAUNCH, but it does not work.
I try to:
- write value 0x89ABCDEF to 0x4002200C address FLASH_PEKEYR
- write value 0x02030405 to 0x4002200C address FLASH_PEKEYR
- write OBL_LAUNCH to 0x40022004 - address FLASH_PECR
And I got NACK in 1st command for setting 0x4002200C address.
And my question, does Bootloader (ST ROM) have access to these addresses ?
