LL_SPI_SetStandard created for STM32L151 although Firmware does not support this call.

Hi Folks, Currently Stm32CubeMx Generator for STM32L151 creates an "LL_SPI_SetStandard" call in spi.c which is not available for that device. That seems to be a bug here.

Hello @stst9180 , @TDK

Thanks for your feedback,

You are right, This is a CubeMX code generation bug, The LL_SPI_SetStandard is not supported for category 1 or category 2 STM32L1 devices as SPI_CR2_FRF bit is not defined for these devices.

The SPI_CR2_FRF bit, which represents the SPI TI mode, is only available in the category 3, category 4, category 5 and category 6 devices and not whole STM32L1 devices.

The devices categories are described in the "section 1.5 Product category definition" of the RM0038 reference manual.

This issue was already detected and raised to the dev team to be fixed. I'll keep you posted with the updates.

It's only defined if SPI_CR2_FRF is defined, which for the STM32L151XB, it is not.

There are many "STM32L151" chips, I didn't check them all. Perhaps be more precise.

Sorry. I'm talking about STM32L151RBTxA.

So in the header it's not defined, you're right.

Unfortunately the CubeMX initializationcode generator still produces the call to that function in the LL initialization code.

Yes, sounds like a CubeMX generation bug.
