asciilifeform: ( where a raster-scanning mechanical 'pinhole' is used, and the distance of source/detector from sample, is varied )
asciilifeform: given as they dun refract -- would need to use something like minksy's confocal method.
asciilifeform: imho it's a promising (and afaik 100% unexplored, in re chip reversing) method, and , bonus, nondestructive (i.e. inspect and then ~use~ device)
asciilifeform: speaking, upstack, of microscopy, did we ever do the 'why not gamma inspection, like for steel beams' thread ?
asciilifeform: ( somewhat unsurprisingly, d00d in q never returned with the promised docs )
asciilifeform: the schematics whisperer d00d suggested that it also has the uart brought out on hidden pins ; i have a test adapter cable due in this wk that will test this theory☟︎
asciilifeform: ( re 'usb-c' -- it's an interesting item, worx as both usb and power in/out, the thing charges by being connected to mains brick through either of the 2 )
asciilifeform: also the 16GB onboard ssd is rather tight, for serious work i'd mount /home on a sd card.
asciilifeform: right, i was speaking of the minimal unit.
asciilifeform: not the problem. glare from the contacts on pcb. same reason pcb is such a bitch to photograph -- needs good low light sensor, if you simply up the lamp, you nuke exposure
asciilifeform: interestingly, mb doesn't take up all of the space inside the case, there is room for maybe half a playing card's worth of iron (sadly not FG's worth..) inside
asciilifeform: for mass production, will still need to open up the boxen to do the write-unprotect magic (lift battery plug, boot on mains current, reflash, put back) but that's it.
asciilifeform: the soldering, ditto. strictly to make 'unbrickable' test unit for the bootloader attempts.
asciilifeform: http://btcbase.org/log/2018-06-06#1820855 << briefly returning upstack, once i find the uart pins and solder (under microscope, it will be a 1st class bitch) i can try starting with stock rk3399 loader, and welding on the c101pa peripherals init (which i've dug out of google's shitpile)☝︎
asciilifeform: mircea_popescu: c101pa? currently stuck on 'how the fuck to build even google's orig bootloader , out of the fragmentarily pseudo-opensrc pieces', before can even consider backporting their init to coreboot☟︎
asciilifeform: on turdroid they have proper multi, and so typical plebe's pnoje resembles win98 box, with 9000 selfinstalled bg shitwares
