LSDK is a complete Linux kit for NXP QorIQ ARM-based SoC's and the reference and evaluation boards that are available
It is a hybrid form of a Linux distribution because it combines the following major components to form a complete Linux
• NXP firmware components including:
• PPA, a resident EL3 privilege secu
re firmware for ARMv8A.
• NXP peripheral firmware components for DPAA1, DPAA2, and PPFE.
• NXP boot loaders. Two are offered:
• U-Boot, based on denx.de plus patches.
• UEFI, based on TianoCore.
• NXP Linux kernel, based on kernel.org upstream plus patches.
• NXP added user space components.
• Ubuntu standard user space file set (user land), including compilers and cross compiler.
The use of Ubuntu user land is what makes LSDK a hybrid. It is not entirely an Ubuntu distribution because it uses an NXP
kernel, but it still uses Ubuntu user space files. This hybrid is possible because NXP ARM SoC's are standards-based so
programs like bash and thousands of others run without being recompiled.
