Check your chip is real BI 2M flash or dual bank config...

Your code addr seems to load code with 1M offset

it is a dual core M4 and M7

A custom designed board?

Sure that VCAP pins have suitable capacitance, and are at around 1.25V?

Watch also that code uses LDO or SMPS configuration based on design, as these aren't interchangeable and can lead to serious connectivity issues.

hi

it is a custom board, the SMPS are power pins.

so you need to connect them high or low depending on design not to be left floated

hi

every one

i check every thing, but its not the power or the connection. i solved it by connecting the ST-Link VCC to the board VCC. when i connect the external power then i am having the problem

i am having a different problem, i am using dual core but when i program it and start the debugger the it says "Target is not responding, retrying...". i thing it has to do with the TRACK and DEBUG in .ioc file. can you help me with that?

i never used dual core so i am not familiar with it.
