Error: The target hardware identity could not be verified. Please check that the target being connected to is of type Cyclone V SoC (Dual Core)

HI all,

Noob here...

I'm just getting started with Cyclone 5 SoC based dev. I have a De10-Nano board. I can program the FPGA section from Quartus without problem. I can run HelloWorld from DS5 ..... however on occasion I see the following error after debug starts.. it also seems that the FPGA part will reset.

Error: The target hardware identity could not be verified. Please check that the target being connected to is of type Cyclone V SoC (Dual Core) 

Can someone point me in a direction to find out whats up please?

If I set the scatter file to load to OCRAM I don't seem to see this problem.... only on SDRAM....

Thanks,

Mike

Hi,

Are you trying to run a bare metal program?

From Debug Configurations > Connection tab, select Altera > Cyclone V SoC (Dual Core) from the Target Connection.

Recommend if you are trying to run the bare metal program you can refer here:

Hi,

Thanks for your response.

Yes, it's a bare metal program. I have the bare metal PDF already thanks.

Can I ask if there are any bugs in the debugging through DS5 + USB Blaster setup? ..... is it rock solid... or flakey.... I'm just trying to understand if this kinda stuff is normal or if I am doing something very wrong...

Hi Mike,

There is one regarding "failed to load client library", but the workaround is upgrade to SoC EDS v14.1:

https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/solutions/fb152500.html

You could find more in the KDB article link here, by searching "DS-5 USB" , etc..:

https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/kdb-filter.html

I appreciate if you could elaborate on what you meant by, "rock solid or flakey"?

Thanks.

Thanks for the answer. By "rock solid or flakey" I just mean is the debugger+usbblaster+DS5 combination of tools "reliable" or do people often report "problems" ? I am only asking so that I know what to expect. If it is reliable - then this means something is wrong locally with my setup. If it does have problems then I won't spend days and days trying to fix something that I cannot.

Thanks

Hi,

Based on the KDB link that i provided, there are 4 known issue on DS-5 + USB Blaster, but there are workaround provided for each of them.

The 4 known issue are as of 2015, so I would assume now there would be no major issue.

Sometimes, the issue or bug may not be the interface of the DS-5 and the USB Blaster itself, it may be some initialization issue that causes the interface to not work.

Regards.

Thanks, when you say initialization issue do you mean initialization of the HPS by preloader?

Hi,

Yes, proper steps needs to be followed to bring up the board. More info can be found here:
