Request for TJA1128 driver files and guidance on LIN transceiver and watchdog usage

Hi NXP Support Team,

I am currently working with the TJA1128 LIN Mini System Basis Chip and I am new to this device.

While reviewing the application note AH1801, I noticed that the software example and driver files for TJA1128 are available through NXP DocStore (NDA required). I would like to request access to the example driver source code and reference project for TJA1128.

In addition, I would appreciate some initial guidance on the following points:

LIN Transceiver Verification
- How to properly bring the TJA1128 into Normal mode for LIN communication
- Any important initialization or pin/configuration requirements to verify basic LIN TX/RX functionality
Watchdog Handling
- How the watchdog is expected to be refreshed in Normal mode
- Any timing constraints or typical watchdog configuration recommendations

My current plan is:

First, to verify basic LIN transceiver functionality
In parallel, to validate watchdog refresh behavior from the MCU

Any application notes, driver documentation, or best-practice recommendations for these use cases would be very helpful.

Thank you for your support.

Best regards,
Kasirajan C
