I have got my first STM32L4R7 and made a simple blinky application which was nearly identical to my STM32L476 application. After programming the code into flash with ST-Link (CLI v. the code will not start. I always have to do a powercycle to start my program. Then it works perfect. I did not set any option bytes and no readout protection bits. The same code compiled for L476 starts immediately on STM32L476 but on L4R7 always a powercyle is necessary to start. Any idea?
