Flash rewriting not working properly in "STM32F746" board.

[UdayakumarHidakal]

Hi all,
I am working in stm32f746 board and i used to compile your flash example code by cargo build --example flash --features="rt stm32f746" command, and i flashed in to controller by using probe-run probe-run flash --chip stm32f746zgtx

After flash erasing and rewriting to the same sector in that case it's not writing to the sector, sector remains FFFF's only , and also i am not able to read flash from the stm32 cube programmer, for reading flash again i have to download some normal Led blink program.

• stm32 cube programmer showing error like this Error : ST-LINK error (DEV_TARGET_NOT_HALTED), is there any solutions?
