Hi i have built preloader by using the GHRD for cyclone V SOC and now i want to write the preloader image to microsd along with the bare metal image of the hello world example and then boot up... please suggest me how to do this...

    Hello,

    The pre-loader and bare metal image need to be programmed onto the SD card seperately.

    There's a description of how to make bootable images and where to progran them in the "Altera SoC embedded design suite user guide". You can find this document here: www.altera.com/literature/ug/ug_soc_eds.pdf.

    Read chapter 8 of this guide, particularly the paragraph titled "Loading Next Image from FAT partition on SD Card".

    I hope this helps

    Chapter 8 is too big and complex for Baremetal Users, need be writed 8-BM for we! :)

    On my SD card lie 4 files: soc_system.rbf, socfpga.dtb, u-boot.scr and zImage.

    If I rename zImage, then Linux not boot, preloader or u-boon can`t find it !

    May I convert and write my test program to zImage and boot it from SD successful ?

    Quickly, which chain of tools and it keys may I run to make good zImage from hwlib.axf ?
