-===Build environment===+=== Linux ===
  
-Kali Linux on Windows 10 WSL1. Ryzen 5 4500U ~2.35 GHz+[[:tools:buildroot|Buildroot]]
  
-Update host and install required tools for both buildroot and yocto.+[[:tools:yocto|Yocto]]
  
-<code> 
-apt update 
-apt full-upgrade 
-apt install build-essential git libncurses5-dev libssl-dev bc picocom chrpath diffstat gawk zstd 
-</code> 
- 
-If there are issues upgrading KALI on WSL1 the following 
-postinst scripts may need disabling in /var/lib/dpkg/info 
- 
-<code> 
-systemd.postinst 
-polkitd.postinst 
-systemd-timesyncd.postinst 
-</code> 
- 
-Adding exit 0 at the start is the solution. 
- 
-===Buildroot=== 
- 
-Fetch 
- 
-<code> 
-mkdir -p src 
-cd src 
-git clone git://git.buildroot.net/buildroot 
-cd buildroot 
-</code> 
- 
-Buildroot supports the 157A and the only difference to the 157D seems to be only CPU 
-speed, 650 compared to 800 MHz. 
- 
-Use the pre-built config 
-<code> 
-make stm32mp157a_dk1_defconfig 
-</code> 
- 
-This config uses linux 5.13 and may not be what you want. See this [[https://github.com/bootlin/buildroot-external-st|page]] for an alternative configuration. 
- 
- 
-Customised config can be created using 
-<code> 
-make config 
-make menuconfig 
-</code> 
- 
-Linux kernel customisation can be made with 
-<code> 
-make linux-menuconfig 
-</code> 
- 
-Build the system 
-<code> 
-make 
-</code> 
- 
-During the above build process it stalled with an uninitialised variable 
-error.
