Hi
I need help in erasing the device: STM32H735IGK3, This device is getting erased only till sector 0.
There were total 8 sectors.
I am following the steps given in  Reference manual for erase operation but still it didn't work.
Could you please suggest something to resolve this issue with Erase?
Or please point out the reason which is throwing this issue.
Thanks!
