### Using the SPI header
|
||||||
|
The SPI header is located on the **bottom** side (see [here][overview_bottom_link]).
|
||||||
|
![][header_cn22]
|
||||||
|
|
||||||
|
### Preperations
|
||||||
|
In order to build coreboot, it's neccessary to extract some files from the vendor firmware. Make sure that you have a fully working dump.
|
||||||
|
```bash
|
||||||
|
[upsquared]$ ls
|
||||||
|
firmware_vendor.rom
|
||||||
|
```
|
||||||
|
|
||||||
|
```bash
|
||||||
|
[upsquared]$ mkdir extracted && cd extracted
|
||||||
|
[extracted]$ ifdtool -x ../firmware_vendor.rom
|
||||||
|
File ../firmware_vendor.rom is 16777216 bytes
|
||||||
|
Peculiar firmware descriptor, assuming Ibex Peak compatibility.
|
||||||
|
Flash Region 0 (Flash Descriptor): 00000000 - 00000fff
|
||||||
|
Flash Region 1 (BIOS): 00001000 - 00efefff
|
||||||
|
Flash Region 2 (Intel ME): 07fff000 - 00000fff (unused)
|
||||||
|
Flash Region 3 (GbE): 07fff000 - 00000fff (unused)
|
||||||
|
Flash Region 4 (Platform Data): 07fff000 - 00000fff (unused)
|
||||||
|
Flash Region 5 (Reserved): 00eff000 - 00ffefff
|
||||||
|
Flash Region 6 (Reserved): 07fff000 - 00000fff (unused)
|
||||||
|
Flash Region 7 (Reserved): 07fff000 - 00000fff (unused)
|
||||||
|
Flash Region 8 (EC): 07fff000 - 00000fff (unused)
|
||||||
|
```
|
||||||
|
|
||||||
|
```bash
|
||||||
|
flashregion_0_flashdescriptor.bin
|
||||||
|
flashregion_1_bios.bin
|
||||||
|
flashregion_5_reserved.bin
|
||||||
|
```
|
||||||
|
|
||||||
|
### Clean up
|
||||||
|
```bash
|
||||||
|
[coreboot]$ make distclean
|
||||||
|
```
|
||||||
|
|
||||||
|
### Configuring
|
||||||
|
```bash
|
||||||
|
[coreboot]$ touch .config
|
||||||
|
[coreboot]$ ./util/scripts/config --enable VENDOR_UP
|
||||||
|
[coreboot]$ ./util/scripts/config --enable BOARD_UP_SQUARED
|
||||||
|
[coreboot]$ ./util/scripts/config --enable NEED_IFWI
|
||||||
|
[coreboot]$ ./util/scripts/config --enable HAVE_IFD_BIN
|
||||||
|
[coreboot]$ ./util/scripts/config --set-str IFWI_FILE_NAME "<flashregion_1_bios.bin>"
|
||||||
|
[coreboot]$ ./util/scripts/config --set-str IFD_BIN_PATH "<flashregion_0_flashdescriptor.bin>"
|
||||||
|
[coreboot]$ make olddefconfig
|
||||||
|
```
|
||||||
|
|
||||||
|
### Building
|
||||||
|
```bash
|
||||||
|
[coreboot]$ make
|
||||||
|
```
|
||||||
|
|
||||||
|
Now you should have a working and ready to use coreboot build at `build/coreboot.rom`.
|
||||||
|
|
||||||
|
### Flashing
|
||||||
|
```bash
|
||||||
|
[coreboot]$ flashrom -p <your_programmer> -w build/coreboot.rom
|
||||||
|
```

# Apollolake

|
## SPI flash layout
|

|
|

|
![][apl_flash_layout]
|
||||||
|
|
||||||
|
With Apollolake Intel invented another flash layout for x86 firmware called IFWI (Intel FirmWare Image).
|
||||||
|
|
||||||
|
Usually on x86 platforms the bootblock is stored at the end of the bios region
|
||||||
|
and the Intel ME / TXE has its own IFD region. On Apollolake both have been
|
||||||
|
