Installing Linux: Hello, Im trying to install linux on my ARM device(cortex A-53). Im trying but its not taking boot from flash drive. Do u guys have any documentation on how to install linux on ARM device(Cortex A53)?

Your problem description is very obscure so that it is not easy to reply in one word.

First, it's better for you to sort out what kind of  Cortex-A53 boards you are using. Usually, the board vendor will provide the Board Support Package (BSP). Different Cortex-A53 boards may have different BSP settings. Some may use the u-boot while others may use UEFI/EDK2, or other bootloaders.  For any types of bootloaders, the "not taking boot" root cause can be different.

Secondly, the Linux distribution Operation System (OS) can be different, which may be Ubuntu, Redhat, CentOS etc.  The reasons that Linux OS fails to boot can also be diverse.

Last but not the least, you have to find out some debug ports from your Cortex-A53 board, which can be the Uart port or JTAG/trace ports.  Based on that, you can capture some booting up log files or do the step-by-step execution with the help of a debugger ( Arm DStream or Lauterbach Trace32 etc).

Good luck!
