Question 1, what is the difference between the following four?

1. Cache: QorIQ SDK V1.9 PPCE500V2 CACHE
2. Image: QorIQ SDK V1.9 PPCE500V2 IMAGE
3. Source: QorIQ SDK V1.9 SOURCE
4. Virtual Host Enviroment: QorIQ DPAA SDK v1.9 PPCE500V2 with Virtual Host Enviroment

Question 2, I just want to use it to compile the uboot of the P2020 processor. It is as convenient as possible to build a development and compilation platform. Which one do you recommend?

1. Cache: QorIQ SDK V1.9 PPCE500V2 CACHE: includes the build Cache for e500v2 platforms to accelerate the building to avoid building anything from the scratch.
2. Image: QorIQ SDK V1.9 PPCE500V2 IMAGE：includes the pre-built image for e500v2 platform.
3. Source: QorIQ SDK V1.9 SOURCE: including recipes, source tar balls. 
4. Virtual Host Enviroment: QorIQ DPAA SDK v1.9 PPCE500V2 with Virtual Host Enviroment: is a virtual Linux environment including QorIQ SDK V1.9.

hello Yiping Wang,

Thank you very much for your reply, maybe you said it very clearly, but unfortunately, I still can't understand the difference between them?

My worry is how to choose, in order to facilitate my own development environment.

Please install both Cache and Source ISOs in the same path.
