I'm using CLRC663 plus and BGM13S, and i wanted to port the reader library to BGM13S. I followed porting guide NFCReaderLibrary_IMXRT1050_CLEV6630B_Porting_Guide . And I followed all the steps given and made changes according to BGM13S. I'm able to read the VERSION_REG from CLRC663, but when i debug the code line by line, in discloop_run() the control is going to default handler and also it is returning DISC_LOOP_FAILURE.
Sorry for the inconvenience this might cause you, but we do not provide support on migrations of the NXP NFC Reader library, and we cannot help you with your specific MCU as we do not have a way to test the device as it is not from our company.
Maybe these other guides for the migration process would be helpful:.
