Resolved! Unable to establish FDCAN communication between two different NUCLEO boards.

I am trying to establsih communication between a NUCLEO G474RE and a NUCLEO H7A3ZI-Q thorugh FDCAN. I have successfully accomplished FDCAN communication for both the boards individually using Normal mode as these boards have multiple FDCAN peripheral...

Resolved! Getting ST-LINK-V3 MODS to run after previous used of nucleoboards.

Hi,i was hoping, that the Link-V3 would just work, after i used nucleo boards already. But i was dissapointed. I use the GDB server, and it says:ST-Link enumeration failedError in initializing ST-LINK device.Reason: ST-LINK DLL error.I just checked a...

Resolved! Error in STM32G4 reference manual RM0440, revision 7 (February 2022), section 44.3.3 Message RAM of FDCAN peripheral

Figure 669. Message RAM configuration clearly shows that the message RAM is 0x350 bytes long which corresponds to 212 32-bit words. But later the following example is used to show, how the message RAM of FDCAN2 follows message RAM for FDCAN1:As an ex...

Resolved! In the reference manual STM32G4 Series (RM0440) there is an error in chapter 7.4.2 ICSCR. The description of HSITRIM[6::0] says that the default value is 16. This is wrong. The default value for the G4 processor is 32.

Resolved! Error in Reference Manual - RM0440 Rev 4 - Page 358, section 9.3.13, "Using the HSE or LSE oscillator pins as GPIOs"

The word "OSC_IN" is missing from the following sentence:"When the oscillator is configured in a user external clock mode, only the pin is reserved for clock input and the OSC_OUT or OSC32_OUT pin can still be used as normal GPIO."Should say: "...onl...
