The Apple A7 and Apple A8 chips found in the iPhone 5c, iPhone 5s, iPhone 6, and iPhone 6 Plus are based on the ARM Cortex-A53 and the ARM Cortex-A57. Additionally, the Samsung Exynos 5433 Octa SoC contains the ARM Cortex-A57 and the ARM Cortex-A53 MPCore, while the Samsung Galaxy Note 4 has an 8-core Exynos 5433 processor.
The Nvidia TK1 development board, which has a quad-core ARM Cortex-A15 processor, is currently available for purchase. However, the latest board from Nvidia, known as "Denver", which is rumored to contain the ARM Cortex-A57 and the ARM Cortex-A53 MPCore, is not yet available for purchase.
The Freescale I.MX 6 processor has been widely adopted across various industries for a range of embedded products. Freescale offers the SABRE board for intelligent devices, a development board that features the I.MX 6 Quad-Core ARM Cortex-A9 processor. Boundary Devices also sells their variation of this board with the same ARM Cortex-A9 MPCore. Developers can build a board support package for both the Freescale SABRE board and the Boundary Devices board using OpenEmbedded/Yocto.
When working with ARM development boards, it is important to take into account a few critical features. Specifically, e-fuses should not be blown out of the box and should be left open. The fuses can be blown to fit a specific configuration.
Here is a quick overview of the processors and boards.
