Build the bootable images with QNX IFS

This section describes the detailed steps to build the QNX SBL container sbl_os for the SCB100 board.

Note:

This sbl_os build is supported only for the Linux OS.

Create a working directory, for example, $HOME/bsp/SCB100 and set the SCB100_ROOT_DIR environment variable to point to it.
```
$ mkdir -p $HOME/bsp/SCB100
$ export SCB100_ROOT_DIR=$HOME/bsp/SCB100
                
```
Note:
This working directory can be created anywhere.
Change directory to the working directory SCB100_ROOT_DIR and extract all third party packages downloaded in the previous section. For example:
```
$ cd $SCB100_ROOT_DIR
$ unzip $HOME/Downloads/815611_FuSa\ SW_Component\ for\ QNX\ OS_0.5.1.zip
$ unzip $HOME/Downloads/slimbootloader-master.zip
$ unrar x -r $HOME/Downloads/SCB100_priv_key.rar
                
```
Note:
Assume all third party packages above were downloaded to the $HOME/Downloads directory.
Extract the the fusa-sdk.zip and hello-fusa.zip sub-packages that are included in the Intel 815611 packages. For example:
```
$ unzip fusa-sdk.zip
$ unzip hello-fusa.zip
$ chmod -R +w hello-fusa
                
```
Note:
Make sure that the hello-fusa is a writable directory.
Create a BSP directory, for example, bsp_x86_64 and extract the QNX generic x86_64 BSP that you had downloaded from the QSC in the previous section to this directory. For example:
```
$ mkdir bsp_x86_64
$ unzip -d bsp_x86_64 /home/qnx/qnx800/bsp/BSP_x86_64_be-800_SVN1019295_JBN337.zip
$ ls
'815611_FuSa Software Components for QNX OS_Getting_Started_Guide 0.5.1.pdf'
'815611_FuSa Software Components for QNX OS_Release_Notes 0.5.1.pdf'
 bsp_x86_64
 fusa-sdk
 fusa-sdk.zip
 hello-fusa
 hello-fusa.zip
 SCB100_priv_key
 slimbootloader-master
                
```
Note:
Assume /home/qnx is your $HOME directory and /home/qnx/qnx800 is your QNX SDP install directory. The generic x86_64 BSP you had downloaded from the QSC in the previous section should be in the /home/qnx/qnx800/bsp directory.
Change directory to the hello-fusa/sbl_os_Makefile directory. For example:
```
$ cd hello-fusa/sbl_os_Makefile
                
```
Open the make file sbl_os.mk and update these three parameters to match your environment. For example:
- line 04: BSP_DIR=/home/qnx/bsp/SCB100/bsp_x86_64
- line 20: SBL_TOP_DIR=/home/qnx/bsp/SCB100/slimbootloader-master
- line 24: SBL_OS_SIGNING_KEY=/home/qnx/bsp/SCB100/SCB100_priv_key/OS1_TestKey_Pub_RSA3072_priv.pem
Replace the build file scb100.build by using QNX x86_64 BSP build file $SCB100_ROOT_DIR/bsp_x86_64/images/generic-uefi/x86_64-generic-uefi.build. For example:
```
$ mv scb100.build scb100.build.bak
$ cp $SCB100_ROOT_DIR/bsp_x86_64/images/generic-uefi/x86_64-generic-uefi.build scb100.build
                
```
Modify the virtual attribute from uefi to multiboot in the new build file scb100.build. For example, change line 10 in scb100.build as below:
```
From:
[virtual=x86_64,uefi +compress] boot = {
To:
[virtual=x86_64,multiboot +compress] boot = {
                
```

Setup the QNX environment and build QNX SBL container sbl_os. For example:

$ source /home/qnx/qnx800/qnxsdp-env.sh
QNX_HOST=/home/qnx/qnx800/host/linux/x86_64
QNX_TARGET=/home/qnx/qnx800/target/qnx
MAKEFLAGS=-I/home/qnx/qnx800/target/qnx/usr/include
$
$ make -f sbl_os.mk sbl_os

You now have a QNX SBL Container sbl_os that can boot on the SCB100 board.
