I have not use any of these products, but before you can get any advice from the creator, I’d probably try one of several things:

Use the SD formatter from the SD card Association websites to make sure that your partition scheme is in alignment with the flash block size. OSes such as Windows will not do this 100% correctly for flash media as it’s a little different from normal SSD drive media.

I assume the product uses exfat and not fat32 but verify that. Reformat and immediately use DD to create your files because your logs claims that your current image file is non-contiguous.

See if you can find an option to correctly specify the hard drive geometry. It looks like you’re trying some form of automation by not mentioning it, but the log clearly states that whatever it’s defaulting does not match your image size.

Maybe one of these things will cause something else to shake loose and work.
