Can i observe the 1KB data that it is written over the STM AXI interface from STM ATB BUS ?
what i mean is that i want to send a 1KB data from STM AXI and observe it from the STM ATB with MIPI STPv2 format.
dudu8,
If you've got an already fixed design which is in silicon, there's no way in ARM IP you could track those accesses from an AXI point of view, although there might be some functionality in ARM interconnects (such as CCN-5xx) to track transactions, or you could use data trace on an ARM core to watch CPU accesses, but not from "any master". You can make some assumptions based on the STM Architecture and STM-500 TRM based on the access sizes from a CPU (where you can configure the stimulus port access via STR{,B,H} instructions for example) and what you expect as output in STPv2 trace.
If you're developing an SoC right now, then the ability to do this is pretty much part of your workflow anyway. We're not sure exactly what you're asking for?
