As LSDK for layerscape processor is very large body of software , NXP should include have some training on flow of code as it is very difficult to understand the flow for beginners like me. LSDKUG is not very helpful as it only explains at top level.It does not explain on how to modify the device tree to suit our custom board and so on. Kindly help.
