STM32C071 clock config problem in CubeMX

[TDJ]

Hi ST,

I’m trying to configure the clocks for the STM32C071GBUx MCU in CubeMX (latest version, 6.17).

This MCU has two SPI interfaces, two UARTs, and two I²C peripherals. However, CubeMX only allows me to configure the clock for one UART, one I²C, and no SPI at all.

Am I missing something?

I’ve attached the complete clock configuration diagram below.

Simply catch is datasheet claims independent clock SPI1, but this dont exist in clock tree diagram. Based this on current for this independent block seems ... But back to @TDJ query , simply add to diagram (SPI1) or remove independent info from pdfs

Which diagram? datasheet? reference manual? which page?

Better to indicate which info to be removed in the pdf..

OMG
Diagram i mean MX Clock settings
and independent SPI1 clock is mentioned for example in Table 35 C071 pdf.

I don't see any mention of "independent" wording in Table 35. That table is focusing on power consumption and it shows all the peripherals connected to the different bridges AHB/APB. I don't see why need to remove SPI1 from table 35!

SPI1 is multiplexed with I2S1:

Perhaps CubeMx needs to mention SPI1/I2S1 instead of I2S1.

Ok I see it now:
