kexec hardboot not work..

[sndnvaps]

hi @faust93 ,i have pick up some func from you repo

now i have test the kexec hardboot code ..

i have meet a big problem. the kexec cann't load new kernel to hardboot

my log is below .

from the log, it seems , kernel code cann't load in the origin phy_address -> which i have adjust my origin kernel_code is show as below

my kexec-tools hold at https://github.com/nx511j-multirom/kexec-tools i have ajust the code to point the rd_base && dtb_base to compat Nx511j( Nubia z9 mini)

---

in the end, can you point the key of this problem.

Thank's a lot . Best wish!

my multirom binary && trampoline is working now. but kexec cann't load the kernel to hardboot. it seem's my memory pool have some thing wrong .

---

to some all the memory info from the origin kernel , i have adjust the FDT_MAGIC to 0x310D3D6

[sndnvaps]

the most import things, i have point the dtb_base = 0xc0000000

[sndnvaps]

when i add more debug info,,, i got the things like
