Implement PIC loading in armv8-m qemu,
for example: load address-independent AP ELF in the bootloader,
and the text segment in AP ELF is XIP,
no need to apply for memory and modify it.
Two config:
bootloader abbreviation bl:
use romfs to load ap elf, use the boot command to parse and jump to ap
application abbreviation ap:
run os test
We need to compile ap first, then compile bl.
compile step:
./tools/configure.sh mps3-an547:ap
make -j20
mkdir -p pic
cp boot pic/.
genromfs -a 128 -f ../romfs.img -d pic
make distclean -j20
./tools/configure.sh mps3-an547:bl
make -j20
run qemu:
qemu-system-arm -M mps3-an547 -m 2G -nographic -kernel nuttx.bin \
-gdb tcp::1127 -device loader,file=../romfs.img,addr=0x60000000
nsh> boot /etc/boot
ap> ostest
