Hi,

Is there an example code available for initialising the Ethernet Phy TJA1101B communication?

I found an Aurix example for RTL8211f:

AURIX_code_examples/IfxGeth_Phy_Rtl8211f.c at master · Infineon/AURIX_code_examples · GitHub

But i couldn't able to find one with TJA1101B.

Hi ub786,
RTL8211F/RFL8211FD PHY is via RGMII for data transfer, while TJA1101B is via MII- and RMII-compliant interfaces.
Besides, the fisrt one supports 1000Base-T and has 4 pairs transeiver in MDI mode. The last one has TRX_P/TRX_M for transeiver and supports 100BASE-T1. You could modify the related drivers for migration, below is FYI.
