I was performing simple arithmetic calculation, and wanted to check the data gets stored in Flash and SRAM memory.

While checking the memory browser all I see is ?????. Could anyone guide me, what's the issue here?Memory Browser.png

Perhaps share more details about your board and your ST-LINK, is that authenic? Does this work from STM32 Cube Programmer tools more directly?

Is this a NUCLEO-F401RE ?

You have to halt for it to update ?

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

While suspending, it shows opcodes at 0x08000000, which is starting memory address for flash, but if you look at the screenshot, still it shows ??? mark at other various memory address.

Also, for SRAM memory, it shows the same.

And your in run mode again - so it cannot show ram data; only while cpu halted.

So difficult to understand ?
