asciilifeform: or perhaps i dreamed this.

asciilifeform: iirc there was a continuation, where , something like asciilifeform:'lorica oughta be heavy, but from iron, not lead weights' and mircea_popescu:~'but only the centurion who wears it should get to decide why heavy'

asciilifeform: yes! it

asciilifeform: them

asciilifeform: can't seem to find it nao

asciilifeform: there was an old thread, with the heavy roman lorica

asciilifeform: https://chromium.googlesource.com/chromiumos/third_party/tpm2/+/master << for aficionados. the crypto, such as they are, routines in the cr50 thing. ( even seems to include a kind of orc rsa )

asciilifeform: makes sense.

asciilifeform: which, yes, will be irresistibly attracted to tasties

asciilifeform: there is not a mechanical cure for the need to exclude vermin

asciilifeform: meat in the sun.

asciilifeform: it's the old flies-and-cutlets thread

asciilifeform sadly entirely unfamiliar with subj

asciilifeform: sorta reminiscent of the old rifle thread ( 'good old days, 7.62x54mm mosin, back when people could still aim, make every pop count' )

asciilifeform regularly has this convo thread with pet, 'books sucked less when they had to be stitchbound'

asciilifeform: asciilifeform was one of those weirdos with massive pile of film, and even trunk of old photo gear

asciilifeform: moar, if you have a largeformat cam

asciilifeform: film gives you, what, equiv of 20-30 'megapixel' for phree

asciilifeform: verily

asciilifeform: ok this is where i admit that i have not read the orig idjicy..

asciilifeform: film , for the money, beats the living shit out of digicam

asciilifeform: btw, curious what mircea_popescu's allergy to 'short ooda loop' is. for instance, mircea_popescu , like asciilifeform , seems to have thrown out his film camera, uses electronic one. why not use film, if 'short ooda loop is for lamers' ?

asciilifeform just nao ate it

asciilifeform: yea it was definitely while asciilifeform was in butugychag

asciilifeform: it

asciilifeform: aha!

asciilifeform: http://btcbase.org/log/2016-06-01#1474768 possibly. ☝︎

asciilifeform: mircea_popescu: almost definitely in the symmetrics thread

asciilifeform: mircea_popescu: upstack: possibly you were looking for the http://btcbase.org/log/2017-01-03#1595992 thread ☝︎

asciilifeform: lol

asciilifeform: how would it make sense for it to be ~moar~ subtly boobied than the 101

asciilifeform: that the dev d00d mentioned

asciilifeform: c100pa

asciilifeform: i'm still curious re mircea_popescu's logic re the older box

asciilifeform: 1 eagle is worth 9000 'fuzzers'

asciilifeform: i could use some eagle eyes on the coad, also

asciilifeform: i'm at that magical 'should i throw it out or buy 6'(tm)(r) stage

asciilifeform: same as when driven from real comp (unsurprising)

asciilifeform: however still gives eggog '127' when attempting 'usb_updater -U' i.e. 'start unlock sequence'

asciilifeform: ( 1 end of hose goes into usbc, other end -- normal usb3 jack between the 2 usbc's )

asciilifeform: ... interestingly, the 101 apparently comes with all of the usb debug ~driving~ end crapola, and will happily diddle itself when plugged into... itself

asciilifeform: with no ~obvious~ hole

asciilifeform: in so far as i can tell, the thing implements plain old 'p256' ecctron

asciilifeform: if i can do this, i think i'll skip the small change and take home satoshi's coinz

asciilifeform: aha

asciilifeform: it's a pretty plain boobytrap, wants magic sig to r/w the 'h1' firmware, or to unlock the console (which gives rootkit access to whole ram, cpu, ec, etc via the usb jack)

asciilifeform: i'm actually ~persuaded that the posted code actually runs

asciilifeform: it dun have a seekrit to extract, simply checks pubkey sig

asciilifeform: mircea_popescu: what's that give ?

asciilifeform: like there was in intel's me

asciilifeform: btw the 'h1' turd is a mass of c crapola, chances are there's an overflow somewhere

asciilifeform: aaaha

asciilifeform: mircea_popescu: phuctor dun ecc

asciilifeform: not to mention that it seems to be a ~pogo with eeprom proggy (these dun show on micrograph anyway)

asciilifeform: which is just about practical. but 22nm -- don't hold breath

asciilifeform: mircea_popescu: i'd luuvvvvv a properly photographed bolix...

asciilifeform: it doesn't have a magic symmetric key, there's a ecc public sig thing to unlock the boobytrap and, e.g., erase/reprogram the thing

asciilifeform: mod6: read end of thread, subj is a ~standard arm with eeprom that ( per my experimentation in past 2hr ) actually does seem to contain something like the linked crapola

asciilifeform: snoar

asciilifeform: aa so it's a sad rando anon

asciilifeform: who runs that thing ?

asciilifeform: yea theoretically useful

asciilifeform: aaaaa

asciilifeform: and it's about the logger thing, not #rockchip

asciilifeform: or do i misread the q

asciilifeform: ( he seems to log in erry coupla days, i'ma try him next )

asciilifeform: dunno that the game is worth the candles; better to try an' persuade the 1 useful d00d to visit

asciilifeform: but suggests that the thing is a standard arm chip, with flash ram, that can be rewritten

asciilifeform: https://chromium.googlesource.com/chromiumos/platform/ec/+/master/extra/cr50_rma_open/cr50_rma_open.py << last piece of lulz, for nao: claims to be 'tester's' defuse for the boobytrap. however dun work with my box, it has the 'ccd' console command locked out

asciilifeform: https://github.com/coreboot/chrome-ec/blob/master/board/cr50/tpm2/rsa.c#L651 << magic pubkeyz in the rom

asciilifeform: ( so far errything he said, such that asciilifeform was able to probe, turned out to be troo. if he's a liar, he's a very high-quality liar )

asciilifeform: the 'PINMUX' bit suggests that the informant d00d was telling the truth, thing indeed controls vreg bringup, at least the 3.3v rail

asciilifeform: https://chromium.googlesource.com/chromiumos/platform/ec/+/master/board/cr50/gpio.inc << claims to be the i/o mapping .

asciilifeform: i have reasons to suspect that if it indeed has anything to do with the physical item, it is only partial picture.

asciilifeform: https://chromium.googlesource.com/chromiumos/platform/ec/+/master/board/cr50/ << for threadcompleteness -- the purported src.

asciilifeform: brb

asciilifeform: hence q, wat do

asciilifeform: maybe by 2040 he finishes

asciilifeform: but know what, i'ma lift it before throwing out whole board, for phf

asciilifeform: one's 50k$ of work, other 5mil

asciilifeform: and bolix is a 2um; this thing is prolly 22nm

asciilifeform: phf: they ever did the bolix?

asciilifeform: controller

asciilifeform: it's the kbd cobtrolr

asciilifeform: thing scans it

asciilifeform: matrix kbd

asciilifeform: no kbd, no power

asciilifeform: cuz i'm stumped

asciilifeform: what does mircea_popescu propose ?

asciilifeform: ( why even keep the orig ec )

asciilifeform: has the appearance of a hasty and gnarly glue job

asciilifeform: pretty strange, that they put the kbd through both

asciilifeform: hard to say without schems or xray

asciilifeform: not single line, seems to handle the keyboard matrix also ( for reset combo ) and possibly vregs also

asciilifeform: vertical integration is a thing, google bought a few power plants; but afaik not fab yet

asciilifeform: owning fab is not usually +ev

asciilifeform: lotsa folx have no own fab . e.g. sun microsystems didnt

asciilifeform: stamp reads TWN , taiwan

asciilifeform: what means 1 in 1 out ?

asciilifeform: quite likely, the fella was telling the truth, it's a google.nsa die
