Hi Expert,
A customer found that running two different system software with pn7150 driver on the same board, one can't swipe the card normally and the other can. They run on Android 10 kernel-4.14 Qualcomm sdm660.
1. The abnormal software only adds pn7150 and display driver to the original system. The log file is“logcat_master_mifare_fail.txt” attached.
2. Normal software is to add other drivers to the above system, such as serial port, SPI to serial port, I2C device, 3-color light, etc. The log file is"logcat_newest_mifare_ok-all.txt" attached.
Could you point out the root cause, and give some comments?
Thanks!
BR,
