Hardware Setup:
Infineon Iridium SLB 9670 TPM 2.0 interface with NXP MPC5748G via SPI
Software Setup:
S32 IDE with FreeRTOS

we have connected NXP MPC5748G as a master and Iridium SLB 9670 TPM 2.0 as a slave.
Connection are as below mentioned:

NXP MPC5748G Iridium SLB 9670 PIN
MOSI 19
MISO 21
CLK 23
Chip selc 26
Vcc (3.3 V) 1
GND 6

SPI specification:
1. Baudrate 5000000
2. Mode 0

But we are facing following problems.
1. We are not getting response as TPM_ACCESS_VALID(0x80) from SLB9670 in Startup-wait implementation
2. Not getting vendor id for command TPM_DID_VID( 83 D4 0F 00 00 00 00 00 )

Could you please share your comment on the above issues.
Thanks in advance.
