Hello guys!
We are planning to choose a CPU with Cortex-A53. Our project of C language now working on Cortex®-M7, currently we using "gcc-arm-none-eabi-6-2017-q2-update-win32" to build our C project.
From my searching, Cortex-A53 is released in 2011, and GCC 4.8 series tool chain has support this:https://gcc.gnu.org/gcc-4.8/changes.html.
And in the "gcc-arm-none-eabi-6-2017-q2-update-win32" Downloading page(6-2017-q2-update), It shows Features：All GCC 6 features.
Is that mean: Cortex-A53 is supported in this tool chain?
Can you guys tell me the answer, thanks a lot!
Apologies this took so long to respond to. There is a compiler specific forum that would be better for this question (I have moved this thread to this forum now).
For Cortex-A53 (and all modern Arm applications processors), they typically run in the 64-bit AArch64 state. For this use the aarch64-none-eabi-gcc compiler.The 32-bit Aarch32 is generally for backwards compatibility (to other application processors), and this code is generated by arm-none-eabi-gcc.
The above are known as 'bare-metal' compilers. There are also Linux specific gcc releases (aarch64-none-linux-gnu).
The latest toolchains are available here:

Note also that the Cortex-M and Cortex-A programming models are very different, and so the existing code will likely need significant porting.
