@ -2455,3 +2455,61 @@ Yep, that causes OpenSBI to not emit any message in the console, so let's put it
back in 0x40001000.
Next, we may want to place the FDT in the previous location, at 0x80017000.
=> setenv bootargs "root=/dev/ram0 loglevel=7 debug rw earlycon=sbi console=hvc0 trace_event=initcall:* trace_options=sym-addr tp_printk trace_buf_size=1M"
=> setenv ramdisk_size 12614846
=> booti ${kernel_addr_r} ${ramdisk_addr_r}:${ramdisk_size} ${fdtcontroladdr}
Hmm, continues to hang in the same point:
[ 2.852200] initcall_start: func=check_unaligned_access_all_cpus+0x0/0x1d4
With this regions:
OpenSBI v1.4

I will also try 0x80013000 as address as I saw it being used before, but I don't
think it is the problem. It must be related with how the initialization is now
different.
