Problem to connect Nucleo-NFC08A1 with STM32F205VET6 via SPI

[CT-55555]

Hello everyone, 

I try to connect the Nucleo-NFC08A1 board with a STM32F205VET6 via SPI. I'm also using the X-Cube NFC6  software extension and tried polling. 

                   STM32F205VET6            NUCLEO-NFC08A1

SCK:           PC0                           -     ST5 (Arduino Connectors)

MISO          PC1                           -     ST6 (Arduino Connectors)

MOSI          PC2                           -     ST7 (Arduino Connectors)

/SS             PD0                           -     ST7 (Arduino Connectors)

IRQ            PD1                           -     ST7 (Arduino Connectors)

I know its required to change the ports in platform.h but I could not found it. Can someone help me? Is there something else to change ?

Hi,

if you have used STM32CubeMX and the X-CUBE-NFC6 3.0.0 package and configured this through STM32CubeMX, there should be no need for modification. For example:

Can you elaborate more on your issue: is it a compilation issue or an execution issue? If it an execution issue, have you properly configured the PD1 as GPIO_EXTI1 and enabled the EXTI Line 1 interrupt in the NVIC configuration?

I would recommend to set the ST25R_SELFTEST and ST25R_SELFTEST_TIMER compilation switch and make sure that st25r3916Initialize returns no error.

Hi BT, 

it's more like a execution because i tried to analyze the SPI with an Logic Analyzer and I don't receive any data.

The Programm get's stuck when it tries to check the st25r3916CheckChipID(). It wants to read the Identyty register but did not get any value back.

Hi,

I suggest to check the SPI configuration. Typical configuration for SPI on X-NUCLEO-NFC08A1:

Feel free to share your ioc file.

Hi Brian, 

I checked the configuration and everthing looks the same.

Hi,

can you share some information regarding your Hardware setup:

• do you have a custom STM32F205VET6 MCU board? is there some arduino connectors on this MCU board?
• how is connected the X-NUCLEO-NFC08A1 to the MCU board: wire jumper or has the MCU board some arduino connectors
• how is powered the X-NUCLEO-NFC08A1? Make sure CN6.6 and CN6.7 are connected to GND. Make sure 3V3 is connected to CN6.4. Make sure 5V is connected CN6.5
• SPI:
  • is SPI3 CLK properly connected to CN5.7 on the X-NUCLEO-NFC08A1
  • is SPI3 MISO properly connected to CN5.6 on the X-NUCLEO-NFC08A1
  • is SPI3 MOSI properly connected to CN5.5 on the X-NUCLEO-NFC08A1
  • is SPI3 CS properly connected to CN5.4 on the X-NUCLEO-NFC08A1

Can you connect a logic analyzer on CN5.7/6/5/4 (SPI) and provide the log file?

Hi Brian, 

I found the reason for my problem. You forgot to connect CN6.4. to +5V. Thank you for your help I hope you're doing good.
