I have a BeagleBoard like that in a drawer somewhere. Getting it to boot from USB may be a reason to fiddle with it again, sounds fun.
As a side note, I want that reasonably priced <https://github.com/ataradov/usb-sniffer>.. I've felt the need for one several times (I've always enjoyed work which involves looking at problematic low level traffic data, for some weird reason). But soldering a QFN chip is not something I'm set up to do, unfortunately. However, apparently AliExpress sells them pre-built.. though Taradov himself states "Do not buy CY7C68013A from eBay or AliExpress, they all are either fake or sketchy". I wonder if that also applies to pre-built boards including that MCU.
The sketchy part comes from no buffering/clamping/conditioning of inputs on those $5 "logic analyzer" ebay boards. Means you only get CMOS compatible signal levels* and might fry it with bad signal, but at prices like this https://pl.aliexpress.com/item/1005003649856071.html blowing a few is a non issue.
* meaning you need to know your probed signal will work beforehand, for example by verifying with a scope first.
