STM32F070CBT6TR does not run

[JPehl.1]

Hi.

I am using MCU STM32F070CBT6TR on my custom board, I do use ST-LINK/V2 as hardware tool, and I have configured the boot options according to this:

 

But in fact the MCU is not running the code, it keeps in lockup state, and then I am not able to debug the code on Utility nor in the IDE, because the MCU doesn't even run. 

Pin 44 (BOOT0) is connected directly to GND.

Pin 7 (NRST) have a pull-up of 4.7K and is measuring 3.3V

What I am doing wrong?

Maybe Note 1 is active , have you realy loaded code to start ADDR flash.?

Hi.

What you mean with "Note 1"? I don't know what is this.

Yes, we can read the binary that we downloaded to its memory.

Note 1 is under your table on image about boot modes. And you can load and read binary, but on bad address.

Too try uncheck nBoot1

Hi.

unchecking "nBoot1" makes no difference.

Theoretically the binary is being put at the correct memory address, and the empty check was validated, and we should consider that the content is at address 0x0800 0000

 

Is there any other detail that could still make the system boot at system memory and not on flash memory?

Hmm possible is two problems when you use bin. Maybe code need be loaded to other address and on start need bootloader code.

Too your 0 vector 2000C000 isnt as i see standart, but when i good rememmber start prog is +4 and this seems be ok.

I recommend debug code, because here we stucks.

Hi.

Problem solved...

We changed the lib used to generate the binaries.
