qemu-system-arm kernel parameters? #477

Closed berni421 closed 7 years ago

berni421 commented 7 years ago

Which kernel related parameters should be passed to qemu to boot the pre build images please?

The image partition 1 contains:- boot.bin devicetree.dtb uEnv.txt uImage

$ file boot.bin devicetree.dtb uImage uEnv.txt boot.bin: data devicetree.dtb: Device Tree Blob version 17, size=10206, boot CPU=0, string block size=962, DT structure block size=9188 uImage: u-boot legacy uImage, Linux-4.6.0-xilinx, Linux/ARM, OS Kernel Image (Not compressed), 5180496 bytes, Mon Dec 19 15:17:00 2016, Load Address: 0x00008000, Entry Point: 0x00008000, Header CRC: 0x259B5828, Data CRC: 0xA59FBAE2 uEnv.txt: ASCII text

First guess. Leaving out boot.bin, and uEnv.txt which appear to have no obvious parameter equivalence in qemu:

$ sudo qemu-system-arm \ -M virt \ -cpu cortex-a15 \ -m 256 \ -kernel uImage \ -dtb devicetree.dtb \ -append "root=/dev/vda2 rw console=ttyAMA0 --" \ -drive file=/home/vm/realp/red-pitaya-ecosystem-0.95-debian-8.6-armhf 20161219.img,if=none,format=raw,id=hd0 \ -device virtio-blk-device,drive=hd0 \ -nographic

sadly gives:-

qemu: fatal: Trying to execute code outside RAM or ROM at 0x00008000

I'm using the pre-built images with the Red Pitaya board. I never used qemu-system-arm. So, I'm afraid that I can't help you with this.
