Board settings
==============
Connect the jumper resistor R554 2-3.

I couldn‘t find R554 jumper on LPC5536/LPC55S36 Evaluation Board

.Guess there is a fault in Readme.txt description.

Hi,

Thank you so much for your interest in our products and for using our community.

Jumper resistor R554 exists on LPC55S36-EVK schematic revision D. Please download from LPC55S36-EVK Design Files.

Hope it helps you.

Have a nice day!

Hi Leo
Thanks for your effort to reply to me.

I just followed your link and download the LPC55S36-EVK schematic revision D

I did found the R554 resistor located at left side of R421 on schematic drawing.

But I found the actual EVK doesn't exit R554 beside R421.

By the way , my EVK is NXP LPCXpresso55S36 B.V. version .

My Installed SDK version is 2.14.0(731 2023-07031), Manifest Vesion is 3.13.0.

So help to check if there is a fault. Thank you very much.

Since there is no R554 for me to short 2-3,I think it is shorted internal

But when i run master_read_sensor_icm42688p demo, it just stopped after Comport Output as below

I3C master read sensor data example.

I3C master do dynamic address assignment to the sensor slave.

So I couldn't readout gyro and accelerator data.
