UFS support

[HeyMeco]

Hello, is anyone working on UFS support (for change storage and writing 4k block size image files)?

@invoxiaamo how did you find out which numbers to send? Can you figure out which number correlates to "SATA" as that is the one used for UFS too?

I only used reverse engineering techniques, looking at the USB urbs exchanged between the windows application and the loader..

• run windows in a virtualbox guest on a linux host
• on linux sudo modprobe usbmon and sudo wireshark
• play with the windows loader application and detect what is modified when you change the storage.
  Not an easy task...

So you need a working solution first with another setup that already worked correctly.
It is a shame rockchip doesn't provide its loader source code, it would simplify everything 😩
