I'd like to use a ST-Link Utility to extract F/W

I'd like to use a ST-Link Utility to extract F/W

The device I'm using is the "STR736FV0T6"

and I have ST-LINK/V2 and ULINK2

The other day, I had an experience of extracting the one on the STM32F205 device.

Isn't STR736 supported?

I want to know which JTAG and program I should use.

Hi, @HHoja.1​,

welcome to the Community!

The STR736FV0T6 is a very old device based on an ARM7TDMI core with JTAG debug interface.

The Cortex-M based STM32 behave completely different, use SWD (serial wire debug) for debugging.

The ST-LINK only support SWD, so you cannot establish a connection to the STR7.

One of the tools that worked with the STR736 was the STX-RLINK from Raisonnance, possibly the Keil ULINK2 could also establish a connection.

Please contact the debugger manufacturer for the necessary software.

Good luck!

In Keil the ULINK2 should be usable, but you'd have to create/build a fake project, set options to NOT download, and then when the debugger opens you can use the SAVE command to pull out the firmware to a .HEX file.

The ST-LINK Utilities might support the STR7, not sure.

The Segger J-LINK, and assorted flashing tools, certainly should.

Thank you for your interest. I want to know more detail about how to set to options and save command in Keil.

@Peter BENSCH​ I'm touched by your kind reply. Thank you.

Experiment on something non-critical first. Uncheck "Load Application at Startup", automatically turns off "Run to main()"

I succeeded in extracting the hex file with the method you told me.

Like that => SAVE C:\TEMP\TEST.hex 0x80000000, 0x8003FFFF

Thank you so much.

Now I need to download (program) this file to another device. If I download it if I use Log and Display command?
