Respeaker Lite can't install firmware (fails at 97%)

I recently ordered a Respeaker lite board. However, when trying to install the firmware I am facing an error

When I run the command dfu-util -l, I get

Unfortunately I am receiving the same issue. I have tried on 2 separate boards. I am running windows 11 for reference.

Get the same error on linux get to 97% erros with that same message

Typically, the burn-in process gets stuck at 97% because the firmware checksum fails.

Try to re-download the firmware and verify the MD5 checksum of the firmware, it may work!

Here are the correct MD5 checksums for both firmwares:

Problem solved

Instead of saving file as, clone the repo. Saving as makes the fw corrupted

I want to thank all of you who provided a working solution here. I was going crazy trying to figure this out.

Hi All,
I was able to load the usb version of the firmware to the XMOS device the first time and it worked as per the Seeed demo on the website. However, when I then tried to use DFU to load the I2S version, I kept getting the error:
Opening DFU capable USB device…
ID 2886:0019
Run-time device DFU version 0101
Claiming USB DFU Interface…
Setting Alternate Setting #1 …
Determining device status: error get_status

I tried everything on this topic and could not get it to load. I swapped out usb cables and tried a different USB port on my computer.

Finally, the only thing that worked was to go back to Zadig and change the usb firmware to libusb0 (v1.4.0.0). It worked before with the WINUSB driver, but it works 100% of the time when I use the libusb driver. Maybe it is because I am using a Windows 11 computer, but not sure.
Anyway, thought I would post this in case it helps someone else.
