The i.MX 8 series of applications processors based on the Arm Cortex architecture are designed for multimedia and display applications
First one got 2 Cortex A72 Cores + 4 Cortex A53 cores and 2 GPU cores. Cortex A72 are Spectre and Meltdown vulnerable.
Second one only got 4 Cortex A53 cores and 1 GPU core. Cortex A53 are Spectre and Meltdown free.
So, if I were to choose, I'd go straght for I.MX 8 for the security's sake.
Purism makes premium phones, laptops, mini PCs and servers running free software on PureOS. Purism products respect people's privacy and freedom while protecting their security.
i.MX8M contains the A53's, which are in-order (and thus likely not vulnerable to Spectre/Meltdown). The full i.MX8 contains the A72's. Thus, one would prefer the i.MX8M if focused on security.

It'll be up to NXP and distros to support the Librem5.
Since it's an ARM device, this means the booting process is tied to the CPU's driver.
If NXP don't give its source code to kernel developers, you're pretty much screwed as if you were on the Raspberry Pi.
This means that no distro will be stable. On the Raspberry Pi 3, that's is Raspbian (which is crippled of bugs, e.g. A2DP, crahsing softwares, etc), and it's more an unfinished Linux Mint Debian Edition than a real Debian.
since there's no UEFI on consumer ARM devices yet, the situation will pretty end up fragmented like Android and its versions or custom ROMs.
To make it short: Try Raspberry Pi 3 and do distro testing to see how far from expectations things will be.
Reference Manual (Basically the very low level details bootloaders and kernels care about):
(a bit of a dense technical tome at 6801 pages)
Data Sheet:
Hardware Developer's guide:
From microcontrollers and processors to sensors, analog ICs and connectivity, our technologies are fueling innovation in automotive, consumer, industrial and networking.
Eratta:
You can find all of the good stuff here:
i.MX 8M Product Summary Page - Application processors based on Arm*Cortex-A53 and Cortex-M4 cores for Audio, Voice and Video processing applications
Thus, everyone *should* be in better shape than we are with the RaspPi, and Broadcomm's horrible NDA...

I'm so excited to have a handheld device that I can install a stock Linux distro on. If Purism is for real about upstreaming everything and not relying on out of tree mods, then I'm down to pay $600.
I'm still baffled the Raspberry Pi isn't all upstream.

Now dont confuse this with my meaning that they need to rape the user community with obscene profits. What is meant here is that a certain level of performance will cost you money. A $300 phone is only worth while if it performs well.

I thought the same like you did, but since companies will even more spy on us (looking at you new Bluetooth and Wi-Fi protocols !), I'm willing to pay those 600$ this time.
Cortex A53 are pretty enough for decent use at 1080p though, and they're damn fast on phones with proper kernel and OS optimizations.
Also, Cortex A53 (like I.MX8 has) pretty don't suffer Meltdown and Spectre issues at all, and that's fucking great ! <3
Let's just hope that they won't choose Cortex A53 revision 0, or we'll lose 15% IPC performance compared to revision 1 (looking at you Qualcomm !).Last edited by UpsetingFact; 04 February 2018, 04:01 PM.

Guest repliedWell, I'm starting to consider buying Purism Librem. I like the idea of software freedom by Richard Stallman. But, $600 for a phone is too much. I hope, there will be a $300 model, as this is my maximum price for a phone.
