interested in the use of the PRUs in terms of the HSR/PRP functionality that they offer. One question that is key to the application is whether a single PRU with dual cores can support two HSR/PRP enabled Ethernet ports? This would mean that we could, for example, on the AMIC120 support 4 HSR/PRP enabled ports ( two pairs) on the device we are looking to create.
The references and resources TI provide are great:
software-dl.ti.com/.../Industrial_Protocols_HSR_PRP.html
However, I just want to confirm whether or not, given each PRU has two Ethernet interfaces (10/100) per each PRU ICSS and as there are two cores per PRU on the AMIC 120, whether from each PRU we can have an independent pair of DANP/DANH ports?
Also I note that for the AMIC processors, it seems that there is no Linux Support for the HSR/PRP libraries i.e. RTOS only. Is this correct and is it likely to change? … if so when?
