asciilifeform: !Q later tell phf lemme know if you want the magic pill recipe + patched flashrom util for c101pa .
asciilifeform: uboot on c101pa promises to be a long and painful dig.
asciilifeform: in other noose, not only reading but writing the c101pa's boot rom worx. however, a build of rk3399 demo uboot does ~not~ bring up anyffing that produces debug uart output.
asciilifeform: ( for those who did not follow the orig c101pa threads : the box has ~three~ firmware turds: 1) main (8MB) bootloader 2) EC (little arm thingie, has own console , controls all of kbd but the power and reset lines, as well as various voltages, and battery charger) 3) cr50 -- controls power/reset lines, inits the charging brick, and 'god mode' debug over the other 2 chips, i.e. cpu and EC )
diana_coman: wow, congrats asciilifeform on c101pa!
asciilifeform: http://www.loper-os.org/pub/current_c101pa_main.bin << current contents of the W25Q64DW rom.
asciilifeform: bahahaha i have spi rom read/write on c101pa.
asciilifeform: in other noose, i have what appears to be a cured c101pa.
asciilifeform: speaking of this, if any l1 folx wants the c101pa carcass, probes and all, and the spare MBs etc, plox to write in

asciilifeform: phf: are you in the midst of planting the thing on c101pa box?
asciilifeform: phf: fwiw i put my c101pa in the graveyard for nao, it was massive sink of time with ~0 to show for it
asciilifeform: however i used the evil kernel, haven't yet built a kernel for c101pa

asciilifeform: oh , for compleeetness, http://loper-os.org/pub/c101pa/cr50.bin.prod << the 0.3.4 cr50 fw currently installed in my box. ( the offsets above, are valid for it)
asciilifeform: so, meanwhile : finds : key id's seen in http://www.loper-os.org/pub/c101pa/c101pa_unlock_nodice.txt , lead to pay dirt,

asciilifeform: !#s c101pa
guestop: hm, loper-os.org and c101pa
asciilifeform: any folx in l1 who would like to saw away at c101pa but lack the snake ? plox to write in .
asciilifeform: meaningful. i either get a pile of c101pa with rewritable cr50 256kB firmwares, or not.
asciilifeform: incidentally the whole fleet cost about 300 bux; i.e. the cost of 1 c101pa-tron.
a111: Logged on 2018-06-13 00:07 asciilifeform: after $time , phf goes and buys, from amazon, a c101pa , and administers the pill. if it is cured just the same as his current one, the other half of prize is to be awarded.
a111: Logged on 2018-06-12 23:39 asciilifeform: phf: you will test using your c101pa. and so you will need the debug snake, i will need to put the output of sysinfo , ver , brd , etc cr50 console commands into the statement.
asciilifeform: pretty clear imho. obtain a c101pa. obtain the snake ( schematic on asciilifeform's www . ) send to asciilifeform the output of the http://btcbase.org/log/2018-06-12#1824405 . then, judge prospective winners , under condition http://btcbase.org/log/2018-06-13#1824459 . if pill permits overwriting all 256k of the chip, with arbitrary contents , we have a winner. then month later, http://btcbase.org/log/2018-06-13#1824462 .☝︎☝︎☝︎
phf: asciilifeform: i see, i'm sorry, but i don't think i can properly be called a referee under these conditions. i can do independent testing for you though, i.e. test against current c101pa, and against one that i purchase at a time you indicate.
asciilifeform: after $time , phf goes and buys, from amazon, a c101pa , and administers the pill. if it is cured just the same as his current one, the other half of prize is to be awarded.
asciilifeform: phf: you will test using your c101pa. and so you will need the debug snake, i will need to put the output of sysinfo , ver , brd , etc cr50 console commands into the statement.
asciilifeform: currently best i have is http://www.loper-os.org/pub/c101pa/h1.jpg
asciilifeform: the break would ideally be applicable via the http://www.loper-os.org/?p=2415 debug device; or, at worst, by attaching to the test pads on the http://www.loper-os.org/pub/c101pa/h1.jpg pcb.
asciilifeform: then, e.g. the c101pa, becomes a pretty useful, general-purpose arm64 box.
asciilifeform: into all currently available cr50 boards, but in particular the c101pa.
asciilifeform: pretty much whole trip asciilifeform was thinking 'mmm, if only had c101pa...'
asciilifeform: http://www.loper-os.org/pub/c101pa/mb_top.jpg << in far upper right.
asciilifeform: a chinese shop could, for instance, mount the http://www.loper-os.org/pub/c101pa_dbg.jpg ( 'google servo' ) connector, on to the vacant pads. BUT this does not give me anything that i do not already have via the 'suzyq'.
a111: Logged on 2018-06-08 17:15 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: according to amstan , the fella claiming to be a designer of c101pa , everything connected with cr50 is deeply trade secret, and shared with no one outside of google.
asciilifeform: swiftgeek: here, btw, is the factory boot rom (crippled coreboot) from that winbond : http://loper-os.org/pub/c101pa/factory_rom.bin
asciilifeform: c101pa finds various retailers, and, if you dig persistently, asciilifeform's www, and that's currently more or less it.
asciilifeform: September 1, 2017 Asus Chromebook Flip C101PA Bob rk3399 etc
asciilifeform: hence investigation of c101pa and similar

asciilifeform: http://www.loper-os.org/pub/c101pa_open.jpg << machine
asciilifeform: the c101pa itself was introduced in '17
asciilifeform: c101pa also includes a trackpad with flashable blob fw
asciilifeform: swiftgeek: i actually started with attempt to port generic coreboot to c101pa, and ended up finding the cr50 by accident
asciilifeform: to be clear, asciilifeform is working with c101pa .
asciilifeform: swiftgeek: if you'd like to take a c101pa and deball the bga and try this, and post article, i promise to read
asciilifeform: swiftgeek: asciilifeform's orig plan was to sell cleansed c101pa machines. if this said cleansing requires lifting a bga, and attaching a manufactured replacement , we will be talking about considerably different cost than if the machines can be cleansed in 10min via software, via debug snake.
asciilifeform: i am however accumulating a pile of c101pa boards
a111: Logged on 2018-06-11 15:35 asciilifeform: http://www.loper-os.org/pub/c101pa/h1.jpg << observe, cr50 has buncha test pads. i bet half a dozen of these, are used for factory fillup.
asciilifeform: not unless BingoBoingo can find a c101pa in uy
asciilifeform: ( btw another reason c101pa would be a spiffy orc lappy -- it's got no fans/ducts )

spyked: re. nsa laptop thread: olimex ppl (huh, it seems I keep mentioning these folks) have a "diy laptop kit" whose specs are very similar to the c101pa (for comparison: http://archive.is/4cp8W vs. https://www.olimex.com/Products/DIY-Laptop/KITS/TERES-A64-WHITE/open-source-hardware , the latter doesn't seem to archive for some reason). it's a candidate for my (by now long) hw-to-buy list, the "open sores diy" aspect is otoh the biggest
asciilifeform: prolly will have to bite the bullet and throw out c101pa , and try the c100pa .

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: ( tho i am certainly hoping to begin selling pre-cured c101pa boxen in ~this~ mo )
asciilifeform: incidentally ~same pill will work to cure other arm64 chrome iron. afaik the c101pa is the only one with ips panel tho, currently.
deedbot: http://www.loper-os.org/?p=2382 << Loper OS - Open Problem: Forcing MaskROM Mode on the Asus C101PA
asciilifeform: upstack -- rk3328-roc-cc , in case anyone forgot, is a 4core beast; c101pa is a rk3399 with 6 core. oughta be snappier for builds.

asciilifeform: ... this also means that c101pa ( as soon as i have a ready to roll firmware for it ) will be an out-of-the-box gnat dev station.
asciilifeform: and somewhere in http://www.loper-os.org/pub/c101pa_dbg.jpg is the uart, but currently i dun have time to find where.

asciilifeform: incidentally the little 'c101pa' comp , is nifty also on acct of having no exhaust pipe ( passively cooled strictly )
asciilifeform: i suppose this is not bad time to mention that i have experimental gentoo for a deloused (i.e. degoogleated) c101pa laptop
