[Pranil]

Hi ST Team,

I'm using ST's openbootloader using i2c protocol. But facing following issues while implementing using stm32cubeprogrammer and ST-Link V3set:

1. After reset the user application is not running

2. Not able to flash new firmware after 1st time flashing(Checked the binaries: Previosly flashed firmaware binary is at that location)

Please help to solve the mentioned issue.
