challenges
It is. Like on other fields, it appears to be a matter of getting it organized.
Free software people do not have a trusted entity to evaluate projects. A single placeholder which can evaluate a
project technically, promote the project and run a crowd funding. I do not see websites like crowd supply
being such an entity.
400000usd sounds like a lot of money. But it is not. It is 40000 people paying 10usd. If you knew that
most likely the public would get a blue print of an open source 802.11 wifi card, wouldn't
you pay the 10usd? Pay 10usd for a notebook that adheres to the free software foundation's
respect your freedom requirements?

Can you list them?
Quoteturn off to staunch Free Software advocate
Are you referring to the mit license matter? If so, I do not agree
with you. It is like some free software people have not realized, that a license similar
to the mit license grants more freedom, not less. If a person wants to use a
gpl license, I do not mind it. But a mit license grants more options. And the part
which is free stays free. A mit license does not stop any person from adding to
the work and making the added part free. But about a mit license people can protect
what they have added and that may be preferable for the public. Let us say
a manufacturer builds a mainboard originating from open
source licensed information. Then adds some non open source parts. Maybe
the mainboard can be useful to free software people, because the mainboard
still is workable without the non free parts functioning.
That is the approach of riscv.
riscv.org
And the business model of
sifive.com
The main part stays free. My understanding is that openwifi has made
the same decision.

The goal is to release open source technical blue prints of an 802.11 wifi card. Ready
for manufacturing. Hiring people for the task would be about 400000usd. At
the present time such funds are not at hand.
Openwifi got a nlnet.nl grant. Next move is to build a fpga
wifi card device.
Please comment if you think there will be a market for such a device? Which
price should it have?
Should a crowd funding get started, do you know companies willing to join a
double up crowd funding? Thank you.

it appears the pins on the esp8266 12e are also on the orange pi one. Can I connect the
pins to an armbian orange pi one and then test the esp8266 12e? I want
to test if wifi works. Is required software present in armbian?
Or should I get an usb adapter
https://ae01.alicdn.com/kf/HTB1pm33XifrK1RjSspbq6A4pFXaf.jpg?width=1000&height=1000&hash=2000
and utilize a x86 gnulinux computer?
It says the esp8266 12e supports i2c. Does the orange pi one have i2c pins, such
that I can test the wifi of the esp8266 12e from an i2c connection
on the armbian orange pi one? Is required software present in armbian? Thanks. -

connected a SPINOR flash chip
Nothing was connected. You are supposed to run command
flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=512
with nothing connected. And if it returns
Calibrating delay loop... OK. No EEPROM/flash device found. Note: flashrom can never write if the flash chip isn't found automatically.
then there is a chance that spi works on the computer.
Like I wrote, on the raspberry pi 0 it returns
Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
No EEPROM/flash device foundStill the raspberry pi 0 was able to flash the
flashchip.

What do you mean ?
How you can test if spi will work. On libreboot's homepage this test
command is displayed:
./flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=512
It should return
Calibrating delay loop... OK. No EEPROM/flash device found. Note: flashrom can never write if the flash chip isn't found automatically.
./flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=512
does not work on the raspberry pi 0 and orange pi one.
It returns
No such file or directory
flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=512
returns
Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.on both the raspberry pi 0 and orange pi one. Since the
raspberry pi 0 can flash the flashchip of a thinkpad t400 then
maybe the orange pi one also can flash it. Because both
return the same message from
flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=512

Thank you.
After I corrected the code, it might work. Command
sudo ls -l /dev/spi*
returns
crw------- 1 root root 153, 0 jan 30 /dev/spidev0.0
Are there commands such that you can verify if spi has set?
mosi
miso
ceo_n
sclk
On a raspberry pi 0 command
sudo ls -l /dev/spi*
returns
crw-rw----1 root spi 153, 0 jan 30 /dev/spidev0.0
crw-rw----1 root spi 153, 1 jan 30 /dev/spidev0.1
On orange pi one it says crw. On raspberry pi 0 it says crw-rw. A raspberry pi
0 can flash the flashchip of a thinkpad t400. Can the orange pi one do it, if
the orange pi one's spi says crw and not crw-rw?

I could not find a picture numbering the pins on an orange pi one.
Up right pin by the arrow is pin1, pin below pin1 is pin2
and pin left to pin1 is pin3.
http://www.orangepi.org/images/orangepione_info.jpg
I want to use an orange pi one to install libreboot on a thinkpad t400's flashchip. Which of the following pins on the beaglebone black's p9 corresponds
to which pins on the orange pi one?
beaglebone black pin
17 -> ?
18 -> ?
21 -> ?
22 -> ?
gnd -> ?
3.3v -> ?
How much ampere can the 3.3v pin on the orange pi
one provide? The orange pi one's psu is 5v and 4a.
Thank you.

It says, that adding an usb ar9271 wifi card to a pinephone is not feasible because the wifi card uses
to much power.
How much power is acceptable for an usb ar9271 wifi card to use?
I do not have extended equipment. I made the following arrangement.
One pc. Connected an usb power meter.
https://images-na.ssl-images-amazon.com/images/I/61fKDfC3pgL._AC_SL1000_.jpg
Connected an usb ar9271 wifi card to the usb power meter.
Started an youtube video. After that downloaded an ubuntu image. Distance to router about
10yards. One brick wall. Usb power meter displayed about 5.1v and 0.16a.
Is that much? To much to use on a pinephone?
The modem on the pinephone has an usb connection. About the modem, why is the power consumption
not a problem?
I know connecting an usb ar9271 wifi card to a samsung i9100 replicant phone is working terrible. Infrequent
disconnects, battery power level has to be above 90%. Thanks.

Is it?
armbian-config -> system -> nightfly
Then
system -> default
Thank you.

looking a bit around on their site for maintained devices:
all of them have "freedom issues"
Yes, they believe they have selected the best available hardware regarding what can get achieved free
software wise. Replicant itself is free software.
Quoteproprietary display driver
Newest piece of information is, the replicant person got it wrong. The display on the pinephone
does not require non free software to run.
Quotearm chips tend to have some lowlevel CPUs in the SoC to deal with a bunch of stuff AR100 for allwinner, Videocore for broadcom
Similar to the ec on a libreboot computer?
Quote4g modem is directly connected to the SoC you've basically no idea what these parts of the SoC is doing all the time.
The modem on the pinephone has an usb connection to the main cpu. Replicant wants to apply usb
guard knowing it might have no effect.

AR9271, which is a great chip, also has it's own CPU, running it's own closed source firmware from EEPROM, this run on a Tensilica Xtesna 2.1 microcontroller...
Don't forget - the AllWinner SOC also has a hidden core for power management, and it runs it's own firmware - the AR100 - some folks have reverse engineered the blob there
It this similar to the ec on a libreboot computer? I agree it is unacceptable if we do not get access
to the source code. But by fsf's respect your freedom definition it does not matter because
the device cannot receive updates or it cannot get on the internet.

either totally libre, or not
For my part I think as free as it gets is an option which should be taken. It builds knowledge such
that if hardware able to run entirely on free software gets on the market then it will
likely be easier to prepare the software which we want.
Quoteatheros 9271, which does support the ath9k+htc driver, but it's USB, power hungry
You cannot software wise tweak the wifi card to use less power? Shorter range for smaller power
consumption?
I wrote bunnie if he new about a free software wifi card suitable for a phone? He did not.
This was his answer.
solution to the closed firmware problem has been to firewall the wifi chip behind a controller. Basically, we consider everything inside the wifi chip to be insecure. It's conceptually the same assumption as saying the access point is insecure, but with a perimeter slightly closer to the phone. This does mean we are burning extra hardware on a dedicated firewall CPU to manage the wifi chip. It's not the ideal solution,
Fyi. A replicant manager wrote, that maybe the display of the pinephone requires non
free software to work. People on pinephone's irc did not know what he was
referring to. If it requires non free software then a pinephone replicant port is not
an option. Apparently replicant will get a pinephone and then will have
to test the phone.
About the listed hardware in posts here. Pinephone says, people can join
in how the phone is going to be build.

abused to make sales.
If you are referring to replicant I do not agree.
https://www.replicant.us/freedom-privacy-security-issues.php
I tell people purism has been misleading, omitting and vague about free
software and their products. If pinephone gets on sale for the general
public and it gets marketed as a free software or open source
phone without detailing which devices on the phone require non free
software in order to run then I will tell people the company misleads
people.
Quoteath9 card
thinkpenguin told me, the usb 9271 wifi card is still being manufactured. And it should be able
to fit in a phone.

According to pinephone's irc they had not considered the ar9271 usb option. One solution
might be to add a nano usb hub to a later pinephone mainboard. Pinephone's
irc said, there is no sdio slave controller for the ar9271.

Free software is software you may use, share, modify and redistribute.
Replicant has decided to investigate if they can port a replicant version to the phone. Replicant has said, they know
of no phone better about free software. All modems on the market require non free software. Same about
the modem in the pinephone.
A downside of the pinephone is the wifi card, 8723cs, because it requires non free firmware software. On
pinephone's irc I was told, they went for the 8723cs because pinephone could find no viable free software supported sdio wifi
card.
Is it the case, there is no free software supported sdio wifi card for sale?
On pinephone's irc the ESP8089, ESP8266, ESP32 chips were mentioned. Are they computers like
the ardinos? If they are, I expect they are not usable in a phone, because of power consumption.
The chips were mentioned because it should not be inherently impossible to write free
software drivers and firmware for them. Do you know about forums for such matters? Thanks.

likely your SD card.
After I aborted the installation, I reinstalled armbian on the
same sd card. Turning on the orange pi one I got
the mentioned error messages. And gparted on a x86
computer displays an i/o error if I want to format
the sd card.
Therefore I took another sd card, which is 4gb and installed debian
on it. Turning on the orange pi one I get the same error
messages as when I used the first sd card. I think it is unlikely
that the second sd card is defect. The 4gb sd card
is a class 4 sd card. That is not good
enough?

orange pi one
I was installing armbian buster. Then decided to abort the installation and turned off power.
If I install armbian on a sd card and then put the sd card into the orange pi one,
the orange pi one keeps rebooting and display message boot. env
file invalid elf header rebooting. Is the orange pi garbage? Can I reset the orange pi one?
Thank you.

Install it from armbian-config
You reinstall armbian. Run command
sudo apt purge iozone3 armbian-firmwareThen command
sudo armbian-configFrom the menu you select kernel 5.3?
And install it?
QuoteGeneric kernels are not here
I did not know a kernel for arm has to be customized

pine64.com has declared, that in general they do not have the means to contract people
in order to get their products ready for everyday use. I think it is wrong if
free software people who make essential contributions do not get compensation. Fact
is, free software people have not been able to device a scheme to make that
happen. Do you have one?
If pine64.com were to utilize what ever people contribute, paying no compensation,
making money on it and bunker the money for their own uses, then it
would be an abusive behavior. Can you document that that is what pine64.com
is doing? Else you are engaging in derogative claims.
