Support for OM-SE050ARD-E integration with Raspberry Pi 5

[lpsylux]

We have purchased an EdgleLock SE050E kit from NXP and plan to evaluate it using a Raspberry Pi 5. We have followed the steps from online documentation (EdgeLock SE05x Quick start guide with Raspberry Pi) which requires only SDA, SCL, VCC and GND connection between the EdgeLock kit and the Raspberry Pi board with wires connected as described in section 2.1.2.2 Connecting the OM-SE05xARD with wires. We successfully went through all steps for setting up the Rasbperry Pi board but we see only errors while running se05x_minimal from 3.4 Execute EdgeLock SE Plug & Trust Middleware test example. We are also unable to see the SE050E I2C address if we run i2cdetect -y 1

Is there any jumper configuration that we need to be aware of for using this kit with the Raspberry Pi?

Do we also need to provide enable/reset pins from the Raspberry Pi board to the SE050E chip using other wires?

Thank you,
Lucian

Hi @lpsylux ,

Would you please try the following command to detect the device again? 

i2cdetect -y -a -q 1

Please note if the device is on another port like /dev/i2c-2, please use i2cdetect -y -a -q 2 instead.

Hope that helps,

Have a great day,
Kan

I forgot to attach the file that confirms address 0x48 is shown on the Arduino setup.

Hello again,

We tested the basic i2cdetect example on an Arduino Uno board and we can see the SE050 device responding with address 0x48 as shown in the screenshot.

On the Raspberry Pi setup with external wires do we need to also connect the EN and RST pins from the SE050-E to something? We still cannot communicate with SE050 from the Raspbery Pi.

Thanks,

Lucian

Hello, we tried to use the command you shared but we still cannot see the device.
I attached some pictures of how the board is connected to the Raspberry Pi + how the jumpers are set, maybe there is something that we need to change to have it working - please let us know if that's the case.

In the meantime we will test it with an Arduino board since by default the SE050-E is intended to be used with an Arduino.

Thank you,

Lucian

And also tell us if we need to externally set RST or ENA pins from the SE050 board to any specific voltage from the Raspberry Pi board.

Thanks!

Hi @lpsylux ,

Please refer to the following for details regarding connection between OM-SE050ARD-E and Raspberry Pi, please also check the jumper settings on OM-SE050ARD-E according to section 2.1.1 in https://www.nxp.com/docs/en/application-note/AN12570.pdf .

Hope that helps,

Have a great day,
Kan

Hello,

Thank you for your reply. I switched to i2c-2 and could see the SE050 address 0x48 by running i2detect command. Then I had to change some settings so i2c-1 was correctly set to the pins and now i2c-1 is also working.

By running the examples the following error messages (also visible in screenshot):

Failed to open GPIO value file : No such file or directory
Failed to unexport GPIO : Invalid argument
Failed to unexport GPIO : Invalid argument

Are they expected? Should I do any change so these commands are not executed since only I2C commands are used from Raspberry Pi to SE050?

Thanks,
Lucian
