# Foxconn D41S
|
||
|
|
|
||
|
|
This page describes how to run coreboot on the [FOXCONN D41S] desktop from [FOXCONN].
|
||
|
|
The D42S, D51S, D52S are compatible boards with the difference being the CPU.
|
||
|
|
|
||
|
|
## Building coreboot
|
||
|
|
|
||
|
|
The default options for this board should result in a fully working image:
|
||
|
|
|
||
|
|
# echo "CONFIG_VENDOR_FOXCONN=y" > .config
|
||
|
|
# echo "CONFIG_BOARD_FOXCONN_D41S=y" >> .config
|
||
|
|
# make olddefconfig && make
|
||
|
|
|
||
|
|
|
||
|
|

### Internal programming
|
||
|
|
|
||
|
|
The SPI flash can be accessed using [flashrom].
|
||
|
|
|
||
|
|
### External programming
|
||
|
|
|
||
|
|
The easiest to flash externally is to simply extract the SPI flash from its socket.
|
||
|
|
To do this gently take the SPI flash out of its socket and flash with your programmer.
|
||
|
|
|
||
|
|
**NOTE: Don't forget to set the WP# AND HOLD# to 3V.**
|
||
|
|
|
||
|
|
**NOTE2: Make sure to reinsert it in the right direction afterward**
|
||
|
|
|
||
|
|
**Location and orientation of the SPI flash socket**
