extreme cleanup / grandiose gesture
make canoeboot a truly GNU FSDG compliant coreboot distro,
by removing all overly positive reference to Libreboot;
what remains is technical in nature, so as to provide
historical context since Canoeboot is a fork of Libreboot.
I've stated before that I wish to take a more neutral tone
toward the FSF, in contrast to the *coldboot war* of 2023
when GNU Boot started.
Canoeboot was heavily linking to Libreboot, even going so far
as to call itself "inferior" and tell the reader to use
Libreboot.
From now on, Canoeboot will be maintained as though I actually
believed in FSF propoganda. I don't, but its users do. Treat
them with respect. My reason for providing Canoeboot is
precisely that I wish for such people to have a high quality
coreboot distro, much unlike the inferior *GNU Boot* project;
inferior because to this day, it's still based on very old
Libreboot, with not much changed (of any real substance)
relative to the Libreboot 20220710 release on which it forked.
In general, I've also found a lot of stragglers from when
Canoeboot started, where paragraphs referred to Libreboot that
should have actually referred to Canoeboot, or paragraphs
with Libreboot-specific information that does not make sense
in the Canoeboot project e.g. references to vendor scripts.
The resulting canoeboot.org will now look no different to any
typical reader than a typical FSF-aligned project.
There is a next stage to this, which will become apparent to
everyone if I have my way.

"Unbricking" means flashing a known-good (working) ROM. The problem:
|
|
|
|
|
you can't boot the system, making this difficult. In this situation,
|
2024-08-26 02:47:30 +00:00
|
|
|
external hardware is needed which can flash the SPI chip (where Canoeboot
|
|
|
|
|
resides). First, disassemble the machine using the following steps, and refer
|
|
|
|
|
to the external flashing guide linked later from *this* guide.

Lift up the keyboard, pull it back a bit, flip it over like that and
|
|
|
|
|
then disconnect it from the board:\

|
 
|
2023-07-10 15:43:08 +00:00

|
|
|
|
2023-07-10 15:43:08 +00:00
|
|
|
|
|
|
|
|
Disconnect the other end of the 56k modem cable:\

|
2023-07-10 15:43:08 +00:00

|
|
|
2023-07-10 15:43:08 +00:00
|
|
|
|
|
|
|
|
Unscrew those:\
|
2023-10-26 00:10:41 +00:00
|
|
|
|
2023-07-10 15:43:08 +00:00

|
|
Make sure you removed those:\

Disconnect LCD cable from board:\
|
2023-10-26 00:10:41 +00:00
|
|
|
|
2023-07-10 15:43:08 +00:00
|
|
|
|
|
|
|
|
Remove those screws then remove the LCD assembly:\
|
2023-10-26 00:10:41 +00:00
|
|
|
 
|
|
|
|
|
|
2023-07-10 15:43:08 +00:00
|
|
|
|
|
|
|
|
Once again, make sure you removed those:\
|
2023-10-26 00:10:41 +00:00
|
|
|
|
2023-07-10 15:43:08 +00:00
|
|
|
|
|
|
|
|
Remove the shielding containing the motherboard, then flip it over.
|
|
|
|
|
Remove these screws, placing them on a steady surface in the same layout
|
|
|
|
|
as they were in before you removed them. Also, you should mark each
|
|
|
|
|
screw hole after removing the screw (a permanent marker pen will do),
|
|
|
|
|
this is so that you have a point of reference when re-assembling the
|
|
|
|
|
system:

This photo shows the flash chip, near the RAM, with numbers of pins written:

|
|
Refer to the external flashing guide:
|
|
|
|
|
|
|
|
|
|
[Externally rewrite 25xx NOR flash via SPI protocol](spi.md)
|
|
|
|
|
|
|
|
|
|
NOTE: Do not use the 3.3v rail from your SPI programmer. Leave that disconnected.
|
|
|
|
|
For 3.3v, plug your charger into the mainboard (but do not power on the mainboard)
|
|
|
|
|
when the clip is connected. Before removing the clip, disconnect the charger.
|
|
|
|
|
This will provide adequate 3.3v DC at correct current levels. The SPI flash on an
|
|
|
|
|
X60 shares a common 3.3V rail with many other components on the mainboard,
|
|
|
|
|
which all draw a lot of current, more than your flasher can provide.
|
|
|
|
|
|
|
|
|
|
Example command:
|
|
|
|
|
|
2024-01-27 22:35:38 +00:00
|
|
|
sudo ./flashprog -p linux_spi:dev=/dev/spidev0.0,spispeed=4096 -w canoeboot.rom -V
|
2023-07-10 15:43:08 +00:00
|
|
|
|
2024-01-27 22:35:38 +00:00
|
|
|
If flashprog complains about multiple flash chips detected, just pass the `-c`
|
2023-07-10 15:43:08 +00:00
|
|
|
option as it suggests, and pick any of the chips it lists. `spispeed=4096` or
|
|
|
|
|
lower (e.g. `spispeed=512`) is recommended on this board. The flashing becomes
|
|
|
|
|
unstable, on this machine, when you use higher speeds.
|
|
|
|
|
|
|
|
|
|
Reverse the steps to re-assemble your system, after you've flashed the chip.
|
|
|
|
|
|
2024-01-27 22:35:38 +00:00
|
|
|
It should be `Verifying flash... VERIFIED` at the end. If flashprog
|
2023-07-10 15:43:08 +00:00
|
|
|
complains about multiple flash chip definitions detected, then choose
|
|
|
|
|
one of them following the instructions in the output.
|
|
|
|
|
|
|
|
|
|
Put those screws back:\

On the CPU (and there is another chip south-east to it, sorry forgot to
|
|
|
|
|
take pic) clean off the old thermal paste (with the alcohol) and apply
|
|
|
|
|
new (Artic Silver 5 is good, others are good too) you should also clean
|
|
|
|
|
the heatsink the same way\
