I am trying to porting azure threadx for TC397, but im not familiar with AURIX's instruction, and AZURE/threadx is also not support TC397, is there any guide for  me to porting this rtos

Hi,
We are facing issue in tc399.

1.In tc399 we are using I2C_Read_External exapmle code .. we are able to receive the data from I2c as MAC address .. How we  can verify whether the received MAC address is correct or not.

2.Can it is possible to write data to the external eeprom through I2C ?? Ifpossible ..please suggest how we can write and read the data.

As shown in the attached figure, there is a delay between the time when the controller starts to send a bit and the time when it receives the position from the Rx terminal during the sending and receiving of the message, which is the sending node delay.

The sampling point of CANFD in the data field needs to adopt the sending node delay compensation mechanism (TDC mechanism).

When the sending rate of the message data field is greater than 1Mbps, the sending node needs to use the secondary sampling point (SSP) and enable the sending delay compensation mechanism.

ISO 11898 stipulates that when SSP is used, TDC mechanism has two ways: 

1.Auto TDC: Set the SSP to the location where the actual transmission delay (TD) is measured, that is, the CANFD controller measures transmission delay.

2.Fixed TDC: Set the SSP to a fixed position, that is, configure a fixed TD.

What I want to ask is whether the MCU supports Auto TDC and if so, how to configure it. If the MCU does not support Auto TDC, then how to configure the Fixed TDC.
