Using ST25RU3993 RFID with Rpi 4 and it work fine with STUHFL demo code. with debian linux Arm Cortex-A9, Is it compatible as I am getting only empty tags. please guide me.

Hello,

as the STUHFL middleware and demo code is written in ANSI C it should work also on Cortex-A9 if compiled with a proper compiler/toolchain.

If no TAGs are found please check your HW setup and check if tuning is correct applied to the carrier cancelation circuit.

Another common issue is a version mismatch between the board FW and the STUHFL middleware.
