Hi,

Support for an external analog probe via SPI interface is planned as a future firmware extension for J-Link Ultra.
The analog probe as well as the implementation of the SPI interface is not available yet.
The manual should not mention the SPI specification yet since it is still subject to change. We will remove this from the manual for now.

Support for the analog probe via SPI as well as the SPI interface support itself,
is on our ToDo list but please understand that I can not give you a specific schedule yet.


Best regards
Alex

Hi,

in UM8001 there is an information about an "Analog power measurement interface". I can't find more information about it. Does it measure ITarget or are there extra pins which can be used for measurement ? Can you please give more information about this interface? How can this be used - is there an extra tool to get the measurements or something like that?

Best regards,
Jan

Hi,

This thread is more than 2 years old, so luckily it was not already closed...
The reason why there is no more information is that it's still reserved for future use. It's just available by now.
What is possible, is measuring ITarget via pin 19 if the target system is supplied power via this pin.
There is a POWERTRACE API available via the J-Link SDK that allows to capture these data.

There are just other priorities right now than the external analog probe / measurement
interface because it's a lot of work and interest is relatively low compared to other projects in the pipe.

What might be worth a thought:
If you have some analog measurement parts on your target system that can be accessed via the application running on the device,
it would be a possibility to use SEGGER RTT to transfer this data in real-time to a PC application like J-Scope.
RTT allows up to 2 MB/s transfer speed.
