asciilifeform: BingoBoingo -- or anybody else who sometimes frequents heathen pits on www -- invited to spread the link to the cr50 summary there.

asciilifeform: phf: if you are able to build the usb snake -- lemme know which cr50 turd ver is in your box ☟︎

asciilifeform: i was able to flash in the https://gsdview.appspot.com/chromeos-localmirror/distfiles/cr50.r0.0.10.w0.3.4.tbz2 image ; it supports a few moar commands, including 'rma open' returned-to-factory unlocker thing. but result was , unsurprisingly, 'with notes from hitler only' : http://www.loper-os.org/pub/c101pa/c101pa_unlock_nodice.txt ☟︎

asciilifeform: ( 0.3.0/cr50_v1.9308_25_B.45-d65d216 )

asciilifeform: in other noose, i found the vendor binary for my particular box's cr50 (all ver strings match) : https://gsdview.appspot.com/chromeos-localmirror/distfiles/cr50.r0.0.10.w0.3.0.tbz2

asciilifeform: far upstack, re the 'cr50' thread -- asciilifeform woke up today and realized that we can simply cut #wp track on spi rom ( naturally after filling it with e.g. uboot )

asciilifeform: upstack, before i start to fall asleep -- what do we wanna do in re the c101 ? march on with curing the 'ordinary' boot rom, and then sit on the thing pending a successful break of the cr50 booby ? shelf whole thing ? which'll it be

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

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

asciilifeform: even supposing that cr50 were cleanly removable (the designers would have to be idiots, to make it cleanly removable, really)

asciilifeform: at any rate, if d00d was telling even half the truth re 'we had a cpld, in prev machines, and moved it, among else, to cr50 when we got to make own die' then it prolly is not a standard konsoomer loltron.

asciilifeform: it is called cr50. also seems to go by 'h1 secure microcontroller' ☟︎

asciilifeform: 2015 box ? 2015 box. does have cr50 ? my probe + naked eye, will say

asciilifeform: which seems to be an almost exactly same machine ( i had it confused with c100 original ) but sans the cr50
