After looking into the udb-otg configuration: I had an idea for bootstraping of ANY unknown node as long they have an usb host connected to bmc and they allow booting USB storage before eMMC, NVMe, ... . Which most CM4 alike devices have AFAIK. In the Turing Pi BMC-Web UI you can choose betwoon "USB route" options. Would it be possible to connect the T113-S3 with the Nodes USB, so that the T113 can present an USB storage gadget attached with an image file to a node? This would allow boot strapping as well as open node recovery options. Basically the "tpi msd" option the other way around. Any opinions about that? Which usb bus would be the one tinker with in /sys, are dtb modifcations needed?
