Is there a way to get the U-Boot CONFIG_SYS_TEXT_BASE from a running Linux kernel? I intend to replace the kernel partition with U-Boot, but for now it has a functional Linux

Guest12: you can compile u-boot with CONFIG_POSITION_INDEPENDENT and set TEXT_BASE to 0
00:41
<
Guest12 >
Hm, that's interesting
00:43
<
Guest12 >
Are there any board configs that currently operate that way?
00:46
<
Guest12 >
I'm also trying to understand what CONFIG_SYS_TEXT_BASE actually means too. If the SoC loads a GPT partition containing U-Boot, does the TEXT_BASE say where in that loaded block of memory the _start is?
00:56
<
marex >
Guest12: CONFIG_SYS_TEXT_BASE is the initial link address, i.e. where you put the U-Boot binary and jump to that address
00:56
<
marex >
it is usually the same address as where the _start symbol is placed
01:01
<
Guest12 >
Is it possible that the working kernel I have also has a non-zero link address? Is there a way to confirm/check that?
01:01

read through this

Will do, this is for ARMv8 FWIW. I assume it still applies?
01:02

I think there is already similar article on aarch64 too
