Hi,

I have an external flash connected to STM32F722 via SPI. Is there a way to view the content of the flash? Maybe with SEGGER J-Flash program?

Thanks

You can do this with the ST-LINK Utilities or STM32 Cube Programmer, but you need to code an external loader that supports your chip and board choices. ​

If you don't mind using (and building with this patch) openocd:

I just need a tool, without coding, to just view the content of the flash. Thanks I'll try openocd. Any other simpler ideas are welcome.

Unless the external memory appears within the processors memory space this isn't going to magically happen. The processor isn't aware of what and how you have things attached to it.​

Have code in your own app dump the content to a serial port. Create a small debug monitor to allow you to selectively dump regions of it, or upload /download via X-Modem or whatever. ​
