Still no luck. No signal at video, no text in console after EFI stub.
Any ideas why?
Can you try to make earlycon work? I'm sure someone has the magic
parameters
for it somewhere...
Indeed. But they don't work either. Ones which should is
earlycon=uart8250,mmio32,0xff130000
That is very odd. Usually earlycon works. The only case I've found where it
was unintuitively broken was when U-Boot ran in EL3, but I assume you do
have ATF running somewhere, right?
It is supposed to be so.
What you can still try is to recover the kernel log from RAM. For that, boot
up the system, then reset (don't power cycle, use the reset button if
available, otherwise use the reset line on the jtag port if available).
After reset, you should get back to U-Boot. There, run "bdinfo" to find out
the base offset of RAM.
What is the offset here?
=> bdinfo
arch_number = 0x00000000
boot_params = 0x00000000
DRAM bank = 0x00000000
-> start = 0x00200000
This is the offset. It does sound quite weird though, so don't be
surprised if things don't work :).
