Hi all,
Had anyone tried to built link between two TJA1101 automotive Ethernet adapter with S32K148EVB?
I used the phy_tja1101 example project to do init for ENET and PHY, after that I did this for master
PHY_Write(0, 17U, 0x9804);
PHY_Write(0, 18U, 0x8001);
this for slave
PHY_Write(0, 17U, 0x9804);
PHY_Write(0, 18U, 0x0001);
after two boards are configured, I connect the bus (TRX_P & TRX_M) of two boards.
The register 23 is monitor with PHY_Read(0, 23U, &value_check_23), however, I can see the readout is back and forth with 0x4004 and 0x6004 which is SEND_Z and SEND_I but I expect SEND_N when I hook them up also LINK_UP bit should be toggled.
I assume that the link will automatically build that I don't even need to send any command on the bus. Does anyone have experience on this?
