STM32G473 svd file defect

[TMark.14]

STM32G473 svd file (used in STCubeIDE in SFR view) shows FDCAN message RAM as if it was another instance of FDCAN peripheral

Also FLASH OPTR register is missing DBANK bit, or, actually it looks very different from Reference Manual.

Hi,

Thanks @Community member​  for reporting this issue & @Community member​  for bringing it to our attention.

I highlighted it to the team maintaining SVD files who will take care to provide a fixed version.

Internal ticket number: 109123.

I had to keep looking into FLASH peripheral and I found that CR register is missing some of the bits also (e.g BKER).

This particular project is in Atollic True Studio but I use svd file from ST Cube IDE version is 1.6.0

C:\ST\STM32CubeIDE_1.6.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.productdb.debug_1.6.0.202102151443\resources\cmsis\STMicroelectronics_CMSIS_SVD\STM32G473xx.svd

Also I compared the file with what comes from Keil uvision STM pack and it is identical file.

Reference Manual RM0440 Rev 6

Actually I was wrong, the bits are not missing, the description of the registers seems to be for another MCU series.

Hi @Community member​ ,

You speak about FLASH_CR register, right? Because that is true: DBANK bit description is missing in STM32G473xx.svd which is a category 3 device.

Yes, I meant FLASH_CR register, you are right STM32G473 is a category 3 device, and SVD file for it might be missing bits that are related to DBANK feature overall.

What's up?

Is that really a defect in svd file or not or you are still investigating?

You provided an internal ticket number, does that mean I can look at it?

[Amel NASRI]

Hi @Community member​ ,

Internal ticket goes to the team responsible of SVD files maintenance. Unfortunately you don't have access to it.

But I'll keep you informed as soon as I get an update on this regard or even the fixed file. The ticket number makes it easy for us to look for status on the internal base.

Hi @Community member​ ,

You find attached an updated version of STM32G473 SVD file. You can use it, waiting for its integration on the STM32CubeIDE and other IDEs.

Don't hesitate to come back with other feedback you may have.

Are FDCAN bitfields defined backwards?

If I look at FDCAN register they start LSB on the top and MSB on the bottom. Then I look at one of the timers bit definitions and they are defined MSB at the top and LSSB on the bottom.

Also I should have added that in Reference Manual bits are (I think always) defined starting with MSB on the top, and LSB on the bottom.
