Please suggest completely open source ARM board with A53/A7
 

It should boot into Linux or BSD WITHOUT any single BLOB
and following ports should work: USB, SATA, Ethernet, any display
PCI port if present would be desirable too

I do NOT need multimedia like sound, 3D video, etc.

It is a security console for remote administration of servers via SSH and VNC.

Only for work, not for games.

You're designing, you should know what you want. Why ask us?
You don't have to go beyond Ebay. What's wrong with the various RasPi models?

Asking because I am a newbie in ARM field.

Raspberry seems requires a blob to boot which is bad from security point of view.

I need a hardware and software 100% free of active BLOBs without source code.

Someone thinks that Allwinner, STM32, LPC and OMAP can boot 100% free of BLOBs, is it correct?

Please suggest a netbook (tablet with a keyboard)

Cortex A7 preferably AllWinner A20/A23/A31/A33

Thank you very much for your help!

that's a different question.
don't confuse us!

this should make it much easier to find something.

what is this blob you are refering to?

Why ask for help if you know what you want? The choice is made. Mark this solved.

Well, actually I was not able to find any Netbook with integrated keyboard having CortexA7 CPU.

There are a lot of CortexA7 tablets without a keyboard, but I am not sure if it is possible to boot them into general Linux without original Android kernel and without any blobs.

I need just a text mode or a slow X11 without 3D.

But I am not sure even a frame-buffer driver works without blobs with a distro kernel like armbian.

Do you know any manual how to boot Linux or BSD on a popular keyboardless tablet with AllWinner CPU?

i know what a raspberry pi is.
i was asking what blob you were refering to.
nevermind.

From my link above:

Please note a few features of a laptop/tablet I am looking for:

1) Spectre free CPU with "in order" execution and not very modern to avoid backdoors like Cortex A7.
2) Open source drivers in a Linux mainline like for AllWinner A20 realization.
3) Able to boot into FreeBSD/OpenBSD
4) May be it can be a custom made laptop from Olimex Olinuxino A20 like this:

5) USB port able to connect to USB hub with several devices like external USB keyboard, mouse, HDD, etc.
6) BLOB free boot to avoid hardware trojans managing ARM worlds in TrusZone

I think I have to make a custom Laptop based on a CortexA7 AllWinner board compatible with OpenBSD.

You can see an example of such DIY:

They use a special adapter to convert a general Thinkpad Keyboard to USB channel.

I think such adapter can be found in different Android ARM based smartbooks (not sure about Windows Atom smartbooks). Does anyone know which smartbook have a USB keyboard which could be reused in a custom made Laptop?

Moved: This thread is more suitable in <Linux - Embedded & Single-board computer> and has been moved accordingly to help your thread/question get the exposure it deserves.

What do you think about how secure is MIPS hardware of a router like WNDR3800 with 128Mb RAM?

This router can boot into fully free open source LibreCMC.

It can be managed from text terminal via SSH or serial console.

Can I add SWAP on LibreCMC located on a USB flash by swapon command?

Can I then chroot from LibreCMC into another distro like Debian v8/v9 located on a USB flash drive?
Only text mode is needed, NO graphical desktop is needed.
