CubeMx discrepancy with Reference Manual for the STM32F767NIx DMA

[R_1]

Hello,

I am working on a project for a STM32F767NIHx. I am using the STM32CubeMx tool and validating using RM0410. The problem I am having is that the i2c4_tx peripheral is not listed in dma1 stream5 on page 248 of the reference manual. CubeMx, however, gives dma1 stream5 as an option for the i2c4_tx. If I had to guess, I would say that the reference manual is wrong here and dma1 stream5 channel2 should actually be i2c4_tx instead of i2c4_rx, but I was wondering if someone could verify this for me.

Thank you very much for your assistance.

Hi @R​ 

Thanks for the feedback.

You are right, i was able to reproduce the issue and it will be fixed in the next STM32CubeMX release.

Best Regards,

Nesrine.

Thank you very much! I appreciate your time. Dma1 stream5 channel2 is for i2c4_rx- fair enough.
