Discrepancy between STM32CubeProgrammer and reference manual

[Maaz1]

Hi all

For the STM32U5, the reference manual shows the GCCFG register as

but STM32CUBEIDE shows

bit 16(and a lot of other bits) are differing. Is this an error and if so which is the right one

STM32U5 series Arm<Sup>®</Sup>-based 32-bit MCUs - Reference manual

Hello @Maaz1 ;

As mentioned in RM0456 the STM32U575/585 support only the USB on-the-go full-speed (OTG_FS) which the OTG general core configuration register (OTG_GCCFG) have these bits filed:

And the STM32U59x/5Ax/5Fx/5Gx support only USB on-the-go high-speed (OTG_HS) which OTG general core configuration register (OTG_GCCFG) have these bits filed:

If you using the STM32U575 or STM32U585, you need to refer to Section 72.15.15 not 73.14.18 in reference manual.

Which STM32U5 are you using?

Thank you.

Hi

Another discrepancy to support the fact that the reference manual might be wrong 

STM32CubeIDE seems to support the stm32CubeProgrammer and not the reference manual. 

Thank you for the ticket, and I hope to hear from you soon since this is of interest to me as well.

Hello @Maaz1 ,

The reference manual is correct, the issue is related to svd file shared in this link.

To clarify the issue, the STM32CubeIDE and STM32CubeProgrammer toolchains used the same svd file register.

I will let you know when the issue is solved.

Thank you.

Hi, thanks for getting back to me.

That's such a huge error lol, I'm glad I posted it here and followed reference manual instead of chasing ghosts. Thank you for replying, really put me at ease :)
