Hello,I am referencing schematic which connecting between AM3359 and TLK110 on ICE and IDK.AM335x datasheet describes that on ZCZ BALL PRUSS/MII0 Signals are :(SPRS717B P63: Table 2-32. PRU Subsystem/MII0 Signals Description)
- pr1_mii0_col [T10] - pr1_mii0_crs [T13, V5] - pr1_mii0_rxd0 [U4] - pr1_mii0_rxd1 [U3] - pr1_mii0_rxd2 [U2] - pr1_mii0_rxd3 [U1] - pr1_mii0_rxdv [T5] - pr1_mii0_rxer [V3] - pr1_mii0_rxlink [V2] - pr1_mii0_txd0 [T2, V13] - pr1_mii0_txd1 [R12, T1] - pr1_mii0_txd2 [R4, T12] - pr1_mii0_txd3 [R3, U12] - pr1_mii0_txen [R2, T11] - pr1_mii_mr0_clk [V4] - pr1_mii_mt0_clk [R1, U10]
But, Both ICE and IDK have not used U1, U2, U3, U4 signals.Although instead it have used V5, U5, R5, R6, I think they do not have pr1_mii0_xxx function.
Should I use V5, U5, R5, R6?Can they operate as MII I/F?
yes, this is a bit tricky as there is an additional muxing option inside PRUSS. This is already described here.
Also I mention this in the ICE FAQ on the Wiki.
Thank you so much, Frank.And, I am sorry to not have enough prior search.
that is ok. There are so many web and wiki pages nowadays that it is easy to miss something. I am wondering all the time how we could make customers better aware of such things.
