Developer Manual/Tools/Dual Flash
The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
You may do it yourself. That's a great tool getting away from bricks :)
Dual Parallel Flash
-
Dual flash "pie". One for keeping working firmware image. Flash chips are selectable by a tumbler switch
-
Detailed "pie" structure. In a yellow ellipse you can see blue lines, that shows how to bend pins
-
VCC is connected to pull-up resistors
-
Resistors are about 100 kΩ. Please note that green and red wires are also connected to their corresponding flash chip's chip select signal
-
On board with less sockets, so there is enough space to insert PCI cards
Dual SPI Flash
This one might need to make a small PCB
-
On top is DIP flash
-
SOIC flash, also some extension for fitting to board
