Aug 14 13:38:07 <pabs3> DocScrutinizer05: will Neo900 have a similar unbrickable/dual-bootloader setup to GTA02?
Aug 14 13:39:32 * pabs3 also wonders about re-writable firmware on other chips in the system, as demonstrated by BadUSB recently
Aug 14 13:40:50 <pabs3> BadUSB was about USB devices getting their firmware reprogrammed, but I guess the same could apply to SoC/board parts? http://lwn.net/SubscriberLink/608503/4825a718b5bac3f6/
Aug 14 15:06:16 <PaulFertser> pabs3: iirc the omap they use has a ROM bootloader embedded.
Aug 14 15:19:27 <paulk-aldrin> pabs3, for the purpose of being unbrickable, it already is
Aug 14 15:19:59 <paulk-aldrin> on the GTA04, AUX will change the boot order to USB > UART > MMC > NAND
Aug 14 15:20:07 <paulk-aldrin> would be nice to have the same on neo900
Aug 14 15:20:13 <paulk-aldrin> that's rather useful
Aug 14 15:20:33 <paulk-aldrin> what's interesting for security is to have switched read-only memory
Aug 14 15:20:40 <paulk-aldrin> like hardware switched
Aug 14 15:20:56 <paulk-aldrin> for instance with a small DIP switch or two pins to connect to be able to reflash it
Aug 14 15:21:16 <paulk-aldrin> having that for bootloader, and maybe kernel too would be really nice
Aug 14 15:22:06 <paulk-aldrin> I'm wondering how that SD card lock thing works btw. If it's something real in hardware and not just telling the kernel "please, mount this is read-only", that would be interesting
Aug 14 15:22:12 <paulk-aldrin> especially if it also exists in eMMC
Aug 14 16:06:01 <DocScrutinizer51> PaulFertser, paulk-aldrin: (ROMBL) exactly
Aug 14 16:06:19 <DocScrutinizer51> paulk-aldrin: too
Aug 14 16:12:50 <DocScrutinizer51> we gonna try to keep the (unbrickable) boot config of N900 but augment/improve on it
Aug 14 16:13:41 <DocScrutinizer51> you don't expect me to build a device you could brick by hacking on it, would you??
Aug 14 16:14:53 <paulk-aldrin> :)
Aug 14 16:15:40 <DocScrutinizer51> there *might* be some tiny I2C attached sensors that get "bricked" when you do bad things to them. Anyway nothing we could do about that
Aug 14 16:16:01 <DocScrutinizer51> ALS comes to mind, and  accel
Aug 14 16:16:34 <DocScrutinizer51> both IIRC have registers labeled "DO NOT WRITE!"
Aug 14 16:17:42 <DocScrutinizer51> aiui modem shouldbe as umbrickable like N(eo)900, though I cannot guarantee that
Aug 14 16:28:51 <DocScrutinizer51> we just know there's a AT command(?) to update modem firmware, but usually you prolly shouldn't mess with that anyway since the modem firmware is cerypto-signed to ensure untampered approval status
