i.MX8 QuadMax ISO7816 implementation

Hello,

I have a carrier board that contains an i.MX8 QuadMax processor.

I want to connect a SAM card slot to this processor but the manufacturer didn't make physical lines on the carrier board so a connection can be made between the SAM card and the integrated SIM module of the i.MX8 QuadMax (pins SIM0_CLK, SIM0_IO and so on).

Does anyone know how can I implement ISO 7816 communication with a running Linux OS on the i.MX8 processor without using the Linux drivers which use the SIM module?

I would appreciate any kind of help. Thank you in advance!

Hi Nikola

I am afraid this is not possible, sorry. In general one can try simple sim unit test

Thank you Igor on your reply.

It is good to know if it is feasible or not so thank you.

What did you mean by using the sim unit test? What would be the goal of running this test?

test basic sim functionality.

I have been looking for a solution to the problem.

The only solution that I see is to use another microcontroller from the PN7462 family. They have integrated ISO UART modules, but this complicates the design because now there is another uC to program.

Could you recommend another IC that possibly implements ISO 7816 protocol but doesn't need to be programmed? I would use a TDA8037 but it requires that the uC implements the ISO 7816.

Thank you again. Best regards.
