SE050 evaluation with S32K148 board using I2C connection

Hallo

Currently, I am evaluating the SE050 with S32K148 board using I2C connection. SE050 only connected as slave mode with S32K148 board and did not connect any sensors with SE050.

1. I did software reset (Got info from old posts)

uint8_t versionPacket[] = { 0x5A, // NAD 0x20, // PCB 0x05, // LEN 0x80, // CLA 0x04, // INS 0x00, // P1 0x20, // P2 //0x00, // Lc 0x09, // Le 0x66, // CRC1 0xAA //CRC2 };

Sent the above data and got response (I am new to this topic Do not know How to calculate CRC1 and CRC2)

Output ----- 0xa5, 0x90 , 0x00, 0xfb, 0xe9

Now I am bit confusing regarding the applet selection to get the version.

uint8_t versionPacket1[] = { 0x5A, // NAD 0x20, // PCB 0x05, // LEN 0x00, // CLA 0xA4, // INS 0x04, // P1 0x00, // P2 0x10, // Lc 0x00, // Le //0x66, // CRC1 //0xAA //CRC2 };

Is this correct packet??

Do I need to add also the payload (Payload 0xA0000003965453000000010300000000)??

Whats are the steps for evaluating the Se050 chip??

Thanks in advance,

Sai

Hi @saireddy_saredd ,

I think you may evaluate SE050 with FRDM-K64 at first then try to port the code for K64F to S32K148. Please kindly refer to https://www.nxp.com.cn/docs/en/application-note/AN12448.pdf for more details.

Hope that helps,

Have a great day,
Kan
