I am testing the fix for H7 CAN. I will release it in the coming days.

Nice !
If you have some example code for FDCAN, that would also be handy since there is no testhal example right now

No problem for the testing, thanks. Saw that the compile problem is just for one line that copy user provided value in a register, for the H7, the register name and fields are different, will try a a stupid fix with some conditionnal compilation directive to see if the actual driver work on H7 and w...

Hello, any news on this front ?

FDCANv1 is the G4 FDCAN ?

Will take a look of the respective register maps of FDCAN G4 and FDCAN H7

Hi, problem solved for my case. It's an issue with recent ULPI PHY that implement LPM. With old families of PHY like microchip 332x that did not implement LPM, handshake works, but with more recent families like microchip 334x, an additional delay is needed in the handshake. This is explained in ST ...

I had previously asserted that we had an ULPI interface working on H743, but I have to say that we didn't verify that we got the high speed; it's possible that we also got the standard 12 Mbit/s. Good news for ChibiOS : I have ported USB_MSD example from contrib to the discovery F746 and it works p...

Found a DISCOVERY_746 in a drawer, it uses the same ULPI component as our custom card.
Flash ST Application from F7Cube that does MSD over USB HS, and got the very same symptoms : works at 12Mb/s speed limit.
Will use ST forum tomorrow to seek for help

Hello, Welcome to the high speed usb issues club :-) I am also having unresolved problem with a custom H743 board trying to use ULPI at HS speed (480 Mb/s) for MSD (USB storage). For now, I am able to have reliable OTG2 + ULPI + MSD, but ultimately, after host <-> device handshake, speed is reverted...

Hi, sdcErase fails for high capacity SD card. from https://chlazza.nfshost.com/sdcardinfo.html, note 10 => 10. SDSC Card (CCS=0) uses byte unit address and SDHC and SDXC Cards (CCS=1) use block unit address (512 bytes unit). So the test in sdcErase seems inverted tested with if ((sdcp->cardmode &...
