Hello!
I'm using a Zedboard and running simple AMP based on Xilinx XAPP1078. After I copy the files to the SD card,I power on the board.The screen show "Uncompressing Linux... done, booting the kernel.
B ",and the progam stop.what's the problem?
Many thanks !

Just go through the following process to get it fixed
subsystem Auto hardware setting->Advance bootable image storage setting and select sd-card for boot image ,kernel image and dtb image setting
in the system-top.dts I add the following lines
&spi0 {
is-decoded-cs = <0>;
num-cs = <3>;
status = "okay";
spidev@0x01 {
compatible = "spidev2";
spi-max-frequency = <20000000>;
reg = <1>;
};
};
&spi1 {
is-decoded-cs = <0>;
num-cs = <3>;
status = "okay";
spidev@0x00 {
compatible = "spidev1";
spi-max-frequency = <20000000>;
reg = <1>;
};
};
build the images
$petalinux-build
generate BOOT.BIN:
$petalinux-package --boot --format BIN --fsbl ~/Avnet-Digilent-ZedBoard-2015.2/tutuapp.vipimages/linux/zynq_fsbl.elf --fpga ~my_program/my_program.sdk/system_wrapper_hw_platform_0/system_wrapper.bit --u-boot
generate rootfs.cpio with the following command because I want to boot the board with sd-card
$petalinux-package --image -c rootfs --format initramfs
IN the sd card copy BOOT.BIN , image.ub and system.dtb into BOOT partition and rootfs.cpio into rootfs partition then run the following command
$sudo pax -rvf rootfs.cpio
In the last boot the board with this sd card
and the result is, I cannot find any /dev/spidev
even whatever changes I made in the sytem-top.dts after running the above commands these changes has been removed and the file name is system.dts, I also checked result is same if i am not adding the above defined lines in the system-top.dts
