Hi all, I have a question about chainloading u-boot images. Setup: I have a device with a small flash storage. In this I want to store 1 u-boot image (A) and an emergency kernel/rootfs. With this, this storage is full. But there is also an eMMC available. I would like to have the small u-boot image boot to the other u-boot (B), which is stored on
<Letrab>
the eMMC. I have this currently working. But I have a question about the RAM addresses. Should I choose different TEXT_BASE addresses for images A and B ? Or may they remain the same?

<LeSpocky>
what's the reasoning for the following checkpatch warning?
<LeSpocky>
ERROR: do not initialise globals to NULL
<cambrian_invader>
null-initialized constants can get merged by the linker

<LeSpocky>
merged by the linker?
<cambrian_invader>
so you must either skip initialization, initialize them to a non-zero value, manually put them in the data section

<cambrian_invader>
yeah, like the linker will see `int x = 0` and `int y = 0` and merge them into one variable
<LeSpocky>
that would be bad ^^
<cambrian_invader>
yeah, it's an insane default
<cambrian_invader>
I think they have to be the same size/alignment as well, but
<tpw_rules>
huh?
<LeSpocky>
okay then I'll have something more to investigate tomorrow ^^
