009 Embedded Linux-ARM. StorageQueries and discussion related to usage of Linux on ARM based devices. Linux has been ported to a variety of CPUs which are not only primarily used as the processor of a desktop or server computer, but also ARM, AVR32, ETRAX CRIS, FR-V, H8300, IP7000, m68k, MIPS, mn10300, SuperH, and Xtensa processors, It is also used as an alternative to using a proprietary operating system and toolchain.
Today i successfully store a uEnv.txt on the target's sd card which load a further a uEnv.txt stored under tftp directory on host or other server and that final uEnv.txt loads the uImage from tftp server. By doing this i found that now i don't need to plug out the SD card from board every time. If I want to change the some argument to pass to kernel i need to just change the uEnv.txt stored at server ie host(my machine). This will save the SD card slot form any kind of malfunction. I am further looking for decrease the boot time of my board ? what is the boot-up time definition ? what is the DMA copy of kernel on start-up? if anyone knowns please share. And i want to know the key difference between Embedded Linux and RTOS like RTlinux VxWroks?
