I'm using the NUCLEO-H7S3L8 and the max CPU frequency is 600MHz. By default, CubeMX sets VOS is set to 0 (low).But if this were the case, wouldn't it be violating the datasheet where it states 400MHz is the max CPU clock? I've been using 600MHz clock...

I'm looking at CubeMX's generation of the linker file (specifically an unconfigured project using the NUCLEO-H7S3L8) and I notice some discrepancies with certain memory region sizes.According to RM0477, the DCTM - RAM region begins at 0x2000_0000 and...

All I'm looking for is to just somehow set up a GDB server for the NUCELO-H7S3L8 so I can do some debugging. My other board (NUCLEO-L476RG) worked fine using openocd, but my H7 has decided to siphon my precious humanity by being insanely difficult. I...

I'm not much of an avid reader, but does this say what I think it says?When a channel x is programmed for a block transfer in memory-to-memory mode, rearbitration is considered between each single DMA transfer of this channel x. Whenever there is ano...

Today I started to implement DMA for the SDMMC peripheral, and it worked for the most part, but when I got around to doing some sector writes, I started to get CRC-16 mismatches. This was a relatively simple fix, as I was enabling the Data Path State...

I think it is indeed backwards, but the documentation is also a bit inconsistent about this.If the RM says VOS=0 is "low level", this would naturally map to mean "VOS low", and as the DS page I shown above, "VOS low" implies FCPU MAX of 400MHz. Funny...

The VDD50USB pin should be left floating when USB is not used:Connect the VDD50USB pin to VDD33USB. Leaving VDD50USB floating is forbidden and is not guaranteed by design.So should VDD50USB be left floating or not?

If that's the case, then alright, I understand that. Strange use of resources though.

Ok, I spoke too soon I guess, because for some reason, openocd HAS to reset the target. This means I can't just flash the binary and then attach the debugger on later if an error condition occurs. I'd likely have to attach the debugger at the start (...

Yes, I've updated the ST-LINK firmware if that's what you're referring to, but that also wouldn't be the issue since debugging already works in STM32CubeIDE.Regardless, I've finally managed to figure out how to do what I wanted to do though (that is,...
