Hi, I am trying to boot off a kernel image on aarch64. I have the compiled image which I am running by using the command
$qemu-system-aarch64 -machine type=virt -m 2048M-nographic -kernel ~/coreboot/build/coreboot.rom For debugging purposes, I tried to get qemu monitor working first. I was able to get qemu monitor working to print onto my terminal (stdio) This gave me then following : qemu: fatal: Trying to execute code outside RAM or ROM at 0x0000000008000000 R00=00000950 R01=ffffffff R02=44000000 R03=00000000 R04=00000000 R05=00000000 R06=00000000 R07=00000000 R08=00000000 R09=00000000 R10=00000000 R11=00000000 R12=00000000 R13=00000000 R14=40010010 R15=08000000 PSR=400001db -Z-- A und32 s00=00000000 s01=00000000 d00=0000000000000000 s02=00000000 s03=00000000 d01=0000000000000000 s04=00000000 s05=00000000 d02=0000000000000000 s06=00000000 s07=00000000 d03=0000000000000000 s08=00000000 s09=00000000 d04=0000000000000000 s10=00000000 s11=00000000 d05=0000000000000000 s12=00000000 s13=00000000 d06=0000000000000000 s14=00000000 s15=00000000 d07=0000000000000000 s16=00000000 s17=00000000 d08=0000000000000000 s18=00000000 s19=00000000 d09=0000000000000000 s20=00000000 s21=00000000 d10=0000000000000000 s22=00000000 s23=00000000 d11=0000000000000000 s24=00000000 s25=00000000 d12=0000000000000000 s26=00000000 s27=00000000 d13=0000000000000000 s28=00000000 s29=00000000 d14=0000000000000000 s30=00000000 s31=00000000 d15=0000000000000000 s32=00000000 s33=00000000 d16=0000000000000000 s34=00000000 s35=00000000 d17=0000000000000000 s36=00000000 s37=00000000 d18=0000000000000000 s38=00000000 s39=00000000 d19=0000000000000000 s40=000000 Abort trap: 6 I did some searching, this meant that the bootloader cannot be loaded. And realised maybe the ROM qemu is getting is not sufficient. The 'execute outside ram or rom' is usually a jump to somewhere that qemu does not recognize as ROM/RAM. In coreboot*, *Since we expect CONFIG_BOOTBLOCK_BASE is 0x10000 CONFIG_ROMSTAGE_BASE is 0x20000 CONFIG_SYS_SDRAM_BASE is 0x1000000 i.e ROM to start at 64k. So I ran qemu by giving a -m 2048M (for testing) and got something. A window popped out (qemu), I am unsure as to what this is. I am attaching the picture with this mail*.* 1. What is this window? Is this just a serial monitor? If so, why does it pop out on doing just $qemu-system-aarch64 -machine type=virt -m 2048M-nographic -kernel ~/coreboot/build/coreboot.rom ? 2. Also, I checked for the supported mainboard for qemu-system-aarch64 ( http://pastebin.com/m03XmUHU) So I guess we can run with virt. Do I need to add a cpu? I would appreciate any help on this.
