STM32CubeIDE generates bad DMA init code for UCPD on G0B1

[GrahamAU]

I'm using STM32CubeIDE to configure UCPD1 on STM32G0B1KET6N.  My firmware package is FW_G0 V1.6.2

I enable DMA: UCPD1_RX = DMA2 Channel 1, UCPD1_TX = DMA2 Channel 2

The generated code in MX_UCPD1_Init can't compile because the DMA init code is bad.  The section labelled /* UCPD1_RX Init */ should start with this:

LL_DMA_SetPeriphRequest(DMA2, LL_DMA_CHANNEL_1, LL_DMAMUX_REQ_UCPD1_RX);

... but it actually starts with this:

LL_DMA_SetPeriphRequest(DMA2_Channel1, DMA2_Channel1, LL_DMAMUX_REQ_UCPD1_RX);

Compare the first two parameters.  Luckily, the compiler chokes on this and it's obvious how to fix it.  There are 8 lines with this bug for the RX DMA, and 8 lines for the TX DMA.

I don't know if my other UCPD settings influence the bug:

UCPD mode = sink

Dead battery enabled

USB/UCPD1 interrupt enabled

DMA1 4-7 / DMA2 1-5 / DMAMUX1 interrupt enabled

Pins PB15, PA8, PA9, PA10 are all configured for their UCPD1 functions.

Hi @GrahamAU 

Could you let me know which version of CubeMX you are using? I attempted to reproduce the issue on my end, and the code generation worked correctly. Attached my IOC file for reference.

On MacOS:

STM32CubeIDE

Version: 1.16.0

Build: 21983_20240628_1741 (UTC)

I tried your .ioc and it works fine.  But then I changed the DMA channels to DMA2 (not DMA1) and I get my bug.  Give it a try.
