Hello Saeed,
Cortex-A53 is an AArch64 CPU, so indeed, you probably want to use the toolchain which targets aarch64-linux-gnu, which is for compiling code that will execute under Linux on an AArch64 machine. If your target is bare metal (does not use the Linux OS), then you want to use the aarch64-elf toolchain.
Alternatively, if you want to generate code in AArch32 mode (which Cortex-A53 supports), you should use toolchains named arm-linux-gnueabihf (for Linux) or arm-eabi (for bare-metal).

Dear Linaro,
Dear Linaro I'm using arm cortex A53 (mt6735 [part number]). But I do not know which tool-chain I have to use. I found your website https://www.linaro.org/downloads/ on internet. and my guess is aarch64-linux-gnu. can you please guide me through selecting a proper tool-chain.
