Failure in Se05x_API_SessionOpen on SE052F (Raspberry Pi I2C Communication Issue)

[krsuresh]

Hi Team,

I am facing an issue while trying to communicate with the SE052F over I2C using the Plug & Trust Nano Package.
According to the AN14277 application note, I configured the SCP03 keys as follows:

ENC Key: 3ae441c747e32ebc16b3bb2d843c6dd8
MAC Key: 6c18f3d08fee1cb96a3c8de5d3538aaa

However, Se05x_API_SessionOpen consistently fails.

System Information
Platform: Raspberry Pi
Package: Plug and Trust Nano Package v1.5.4
Example used: ex_se05x_GetInfo

Log Details:

./ex_se05x_GetInfo

@Kan_Li I am assuming that the MW will be further delayLast update was 6 months ago based on 31/3/2026 10.16am (+8GMT timestamp)ed?

@Kan_Li 

Thanks for the update on the new outlook. Is there anyway that we can get NXP's commit on this new outlook and not merely just a mirage that will not materialize when end March comes?

I don't know of any other means to voice this distasteful aftertaste apart from swallowing this  news as is and knowing that we cannot make progress on SE052.

Perhaps, we should seriously consider other vendor...

Hi @Ben-FLX ，

GitHub nano-Pkg is now updated, But It is not yet a release， It is a pre-release ，you may simply git clone it for evaluation purpose. The Release process will be completed along with the Main Package release tentatively planned for 31^st March 2026. 

Hope that helps,

Have a great day,
Kan
