Hello,
I had configured in older post
Solved: Re: is there any sample for X-NUCLEO-NFC08A1 to be... - STMicroelectronics Community
an stm32 example for tag polling for stm32u083RCxx family and using a NFC08A1 extension interface like here:
but now after some hw redesign I will not have nfc08A1 board anymore.
Is it enough for me to go back to cubemx example and regenerate it without Board Extension NFC option?
Thanks,
Mihai
Hello BT,
Thanks for your answer.
I thought rfal lib is needed anyway to use st25r3916b driver, not only when using nfc081 ?
My expectation is that I only need to remove that code encircled in the snapshot(meaning to uncheck only the nfc extension board support). Will look at it
Piggybacking off this topic, since the thread mention in the OP is locked now.
Using the same NFC08A1, I'm trying to generate code without the LED and UART COM dependencies, but it seems code generation fails on nfc_conf.h.
To be clear, I previously started from this config:
I cannot use this config, since other than the pins set under "Found Solutions", I have no free pins to assign to the LEDs. Moreover, I've defined my own logger, and I am using the Virtual COM from the BSP -> Human Machine Interface, which occupies USART2. Due to other config options, only USART1 is available, which is used for a different component.
Leaving the pins as "undefined" causes CubeMX to generate code that does not compile, because the #define's for the various LEDs are left incomplete:
These are the pins used here:
Moreover, you can see the generated code uses BSP_COM_INIT(COM1), which is undefined, since no UART option is given to the X-CUBE-NFC6 config.
I've tried moving to a config that only uses SPI and RFAL (which I assume is enabled by the "Wireless MID LIB" option?):
But this causes the generation to fail for nfc_conf.h (fails silently, CubeMX itself reports no error):

at com.st.microxplorer.plugins.projectmanager.engine.GenerateProjectThread.run(GenerateProjectThread.java:61)I've tested with only the 1st option removed (as in the OP), but that results in the same code generation error).
Any guidance on how to proceed w/o defining all the options for the 1st config, or on how to fix the code generation for the 2nd config would be much appreciated.
EDIT:
I would assume changes need to be made to the software package, but i.e. disabling board extension gives warnings:
Generating with only these software packages results in the same nfc_conf.h generation error.
After further testing, it seems the nfc_conf.h generation error happens every time all 4 options are NOT selected, either from software packages or in the configuration itself.
The same error as in the nfc_conf.h file is reported in the terminal when running the generation:
