reading flash memory

[Fate1]

Hi, with stm32cubeprogrammer i've read flash memory, but when i want to program the micro with the file that i've read, it says that "core is locked up". what should i do to solve this problem?

Maybe you copied too much of the flash and the user area is smaller?

What part?

Is the problem with READING or WRITING (Programming)?

What memory area are you accessing?

Perhaps post a log? Select the highest debug level.

By reading i have no problem. In "Device memory" window there is a address bar, data size and data width, that i use the default value for them. Then i choose "save as" and then read command.

By writing i receive these messages:

'Start operation achieved successfully'

'Warning : The Core is locked up'

'Download verified successfully'

'File download complete'

I'm trying to read flash memory.

What do you mean by 'post a log'? I don't understand.
