In tarballs for BR, there is no source for utilities like flash. I'm trying to "decode" this structure, variable-by-variable.

But what about webs, as i looked into, this needs too some knowledge of flash datastructures.? About webs -> will try to add some printf for debugging, and see. BTW, maybe the JP3 connector (just 12 little holes) is the JTAG. Will upload photo i think tomorrow. I have checked this with ohmometer and pin-map of 8186, and it seems to be JTAG + RESET+ something(?). You have published schema of JTAG cable, but what software shall anyone use? W.Piotrzkowski.
