The issue of returning 0x18 error in SPI communication with PN5190

KingJin — Mon, 09 Oct 2023 05:58:46 GMT

PNEV5190BP development board wired to my development board, porting NFcdlibEx6_LPCD to my board. SPI is connected, but there is an issue. After setting SWITCH_MODE_NORMAL (0x20), an error of 0x18 occurs whenever any command is sent again.

As shown below:

I (22516) write data: 7f 20 01 00

I (22542) Read data: ff 80 00 08

I (22543) Read data: ff 01 00 00 00 01 00 00 00

I (22620) write data: 7f 23 00 08 02 00 00 00 00 00 4a 01

I (22656) Read data: ff 23 00 01 18 ff ff ff ff

I modified the program and attempted to read the version number, but encountered the same 0x18 error.

I (41484) write data: 7f 20 01 00

I (41510) Read data: ff 80 00 08

I (41511) Read data: ff 01 00 00 00 01 00 00 00

I (41575) write data: 7f 27 00 00

I (41617) Read data: ff 27 00 01 18 ff ff ff ff

What is the reason for this, please help me, thanks！
