System-Console: get JTAG Hash

Hi,

system-console -debug (print debug info in GUI)

system-console -debug --cli (print debug info in command prompt)

Thanks,

Hi Sheng, this command does not query the JTAG hash.

It just opens the system console.

I am hoping to get an API command where I can query the jtag hash of the device, or all the jtag hashes available. Similar to other ones available:

- get_service_paths

etc

thank you

Hi,

It opens the system-console and the debug info like jtag hash will be printed out in messages windows right? For example like below:

So far if you mean in system-console, there's no command can straight get the jtag hash.

Thanks,

I want to manage multiple FPGAs connected to a computer, in an automated way. For this, I need to be able to read some device ID. The JTAG Hash seems ideal, but there are no APIs available to do so. Can you recommend another device ID that can be read from the System Console API?

Or is there another way to read the JTAG Hash or else from a Windows API?

Whenever the devices get unplugged/rebooted, their USB ID changes (1,2,3,4...), so the USB ID is not enough to identify the device.

thank you

Hi,

The jtag hash is for internal use only.

Why don't you try the command below?:

device_get_board

device_get_connections

get_service_paths

This probably will get the stable device name or device id.

Thanks,

Hi,

May I know the connections section under System Explorer in system console shows multiple devices?

Could you try with different lindex like below:

lindex [get_service_paths master] 0

lindex [get_service_paths master] 1

lindex [get_service_paths master] 2

Thanks,

Hi,

Thanks,
