[NSA325] I'm having trouble building the uInitrd
May 15, 2022 09:42AM
I'm having trouble with installing newer, > 5.14.9 (still I've also managed to break it in another way) kernels. 5.15.5 and 5.17.4 at least. And I don't have an idea what to do about it.

*Is* initrd.img-5.17.4-kirkwood-tld-1 gzip compressed?

`file` says yes:

Dźwiedziu ,

Use 5.17.4-kirkwood-tld-1, interrupt serial console at count down

> Hit any key to stop autoboot:

And then set the load address of load_dtb_addr to 0x2c00000 and boot.

setenv load_dtb_addr 0x2c00000
boot


=========

I've just recall I already wrote this on the u-boot installation thread:

Quote

B. Load addresses for large systems

This u-boot was released in 2017, since then the kernel size has grown quite a bit. So if you intend to run apps or frameworks that take up a lot of space for initrd, you might need to adjust the load address of the DTB (load_dtb_addr). The default env is set up to allow 11MB uInitrd.

In particular, OMV4 running in the latest rootfs will result in the uInitrd larger than 11MB. So the load address of DTB must be moved farther out to accomodate the large uInitrd. This canbe done with 2 alternatives (B.1 or B.2).

B.1 Set the env permanently to give another 16MB to load uInitrd (i.e. allow for initrd that is up to 27 MB in size).

fw_setenv  load_dtb_addr 0x2c00000


B.2 Adjust load_dtb_addr in uEnv.txt

Add this line to uEnv.txt (see section C below). This setting is transient, i.e. not permanent. If the uEnv.txt exists in /boot folder, then it will be used during boot.

load_dtb_addr=0x2c00000

It works, log snip below, thanks!

Can you just tell me how do you calculate the addresses and do I need to recalculate for each new kernel or those just go straight to uEnv.txt/setenv?

Now the above I've wrote between your edits, so now I assume my questions answered ^_^J

Cool :) glad you got the answer you need!

There is better way to ensure the load addresses are OK. But that will be for another day in the future when I will release new u-boot version.
