I work on a custom board AM243x with the last SDK mcu_plus_sdk_am243x_08_02_00_31
I am testing PRP demo application as recommended by your documentation.
I would like to understand statistics (attached here)
I have port A connected to my PC where wireshark collects packets.
TX packets on port A are OK since in wireshark I count the same number of packets coming from the board
RX packets are zero since I don't have another PRP node sending PRP frames
TX packets on port C are the same as Lookup error A: what does it mean ??
Actually, such packets are broadcast or multicast packets sent from my PC: why are they counted as TX instead of RX ?
I inspected the code of ICSSFW_HAL and I found that in hsrPrp_red.c, function RedTxPacket, the counter incremented is LRE_CNT_RX_C: why ? was it a mistake for LRE_CNT_TX_C ?
Anyway, this doesn't explain why the LRE_CNT_TX_C counter is equal to the packets received as broadcast or multicast (I expected LRE_CNT_RX_C).
