Describe the feature you want

It would be great to be able to access the SD card from a host connected via USB to the SKR 3 board similar to #22354.

It seems SDIO support was made available in #24271, but there is no *_USB environment in stm32h7.ini for the SKR 3 and using env:STM32H743Vx_btt with #define SDSUPPORT enabled in Configuration.h and #define SDCARD_CONNECTION ONBOARD enabled in Configuration_adv.h I do not see the SD card when connecting the board to a computer (neither on Mac OSX nor Raspbian).

I tried adapting the environment similar to the changes in #22354 but was unable to get it to compile, probably because I don't really know what I'm doing. I suspect one problem might be, that ${stm_flash_drive.platform_packages} requires an older version of ststm32 than is requested in stm32h7.ini for the SKR 3 board.

I suspect one problem might be, that ${stm_flash_drive.platform_packages} requires an older version of ststm32 than is requested in stm32h7.ini for the SKR 3 board.

That and the SKR 3 does not have a USB A socket for flash drive support.

I agree with the request to add this option to the SKR3 EZ board please..

Follow up on this, a much needed feature. 👏

These should be standard features that must be implemented across all boards/firmware versions.

I'd like to add a request for USB mass storage access through USB for the SKR3 as well.

To get this functionality, we'll need an upgrade to https://github.com/rhapsodyv/Arduino_Core_STM32/tree/usb-host-msc-cdc-msc-3 … with a little guidance from @rhapsodyv. I looked over the differences between the previous Arduino_Core_STM32 and the new one, and there are some refactors in there, so it looks like some changes might be needed to get it all functioning.

I also would like this since we can't use usb to push firmware. Would love to not have to open the printer every time.

same same here skr 3 ez marlin 2.1.x bugfix

[Fabface]

is this supposed to be working now? I can't access the SD over USB (Marlin 2.1.2.1)

is this supposed to be working now?

No, this feature request is still open.

I want to push this request .. For me it's about firmware updates via octoprint
