_49616e is there are reason you need/want to replace bl33?
<chewitt>
or, what's the reason?
sputnik_ has joined #linux-amlogic
<chewitt>
as a rule SBCs are well supported with mainline u-boot, but box devices are best left with vendor u-boot
sputnik_ has quit [Remote host closed the connection]
sputnik_ has joined #linux-amlogic
<_49616e>
This is a tv box that I want to run mainline u-boot on. They've got an annoying splash that I want to get rid of, plus I want to experiment with UEFI on arm64.
<chewitt>
the challenge will be that S905L is a low-end version of the SoC, and low-end devices tend to take more shortcuts with RAM chips, so it's hard to build mainline without FIP sources tweaked for the right RAM timings
<chewitt>
make sure you back-up the emmc before you erase it for experiments
<_49616e>
but I'm playing with u-boot, so if things go wrong there won't be a functional vendor u-boot for me to boot Linux with

<chewitt>
if the S905L board has an SD card you should be able to write the emmc dump to SD card and boot it
<chewitt>
it might not boot fully to the OS, but the initial u-boot stage should be detected and work
<_49616e>
> I have boards that doesn't have MicroSD slots, which naturally makes recovery very difficult if something goes wrong.
<chewitt>
so does the S905L have an SD card slot or not?
<chewitt>
it's not clear if you mean "this board" or "boards" in general
<chewitt>
each device prob. needs it's own approach
<_49616e>
I asked about the amlogic Windows utility because I do have boards without MicroSD card slots.
<_49616e>
All of the boards that I'm *currently* playing with do have MicroSD slots, and that's what I've been using to test mainline u-boot.
<chewitt>
mainline u-boot will prob. run fine on the board, it's the earlier stage bits (closed source Amlogic code, board specific bits) that will be the problem
<_49616e>
which is exactly why I was trying to replace bl33 and keeping everything else stock
<chewitt>
have you tried to edit the u-boot script that loads the splash?
<_49616e>
This doesn't solve the UEFI problem.
<chewitt>
which distro are you trying to run?
<_49616e>
I'm not trying to solve a practical problem here, the distro is irrelevant. My goal is to have mainline u-boot on this board, not booting some distributions that otherwise wouldn't work without UEFI.
<_49616e>
Fedora is a very good example if you *really* want to know. Their arm64 images are pretty much RPi-specific because they chose to use u-boot -> UEFI instead of loading the traditional legacy image directly.
<chewitt>
lvrp16 what's the status of UEFI boot these days? .. I know you were working on Ubuntu support?
<lvrp16>
chewitt: efi boot works fine since last year, just need to work on efi runtime services
<_49616e>
I managed to get Fedora's arm64 image to work (kernel included) on allwinner H5 with mainline u-boot, but grub2 doesn't want to start Linux on my gxm board and it won't tell me why.

_49616e: is grub going through the shim?

chewitt: I have been cleaning up my own very dirty u-boot code and trying to make it maintainable and support all of the features I want. Probably be finished the second week of July after 2020.07 is release.
<chewitt>
nice
<lvrp16>
chewitt: testing hell though, no CI all manual, h3, 2 h5, s805x, 2 s905x, s905d, s912, rk3399, also linux min-configs for each of those XD
<chewitt>
sounds like my LE kernel bump routine
<lvrp16>
also so many bugs in distros upstream, so many kernel versions, and so many different kernel features and boot mechanisms
<chewitt>
only that's now about 22x different GXBB > SM1 devices
<lvrp16>
haha doing the job of the box manufactures for them :D
<lvrp16>
should organize a mechanism and tell the box manufacturers to do their damn jobs

I think it was called Project Hailstorm? .. Google is probably the only entity they all care about

repk: so is there a straightforward way that I can just carve bl2 out from the emmc dump?
<_49616e>
Looks like I'm still missing acs, bl21, bl30, bl301 and bl31 so far.
<_49616e>
Would I be able to extract bl30, bl301 and bl33 from the emmc dump with these info?
<repk>

(acs, bl21 are in bl2.sign)

Is the first 2MB enough? I could email it to you in a sec.
<repk>
Yes should be more than enough

Maybe S905L uses amlogic boot image version 2. If it does gxlimg does not support it. It will eventually at some point as soon as I find a bit of time/courage to disass the binary again.

thats bl301 with CEC stuff

CEC was implemented in bl301? Interesting.

_49616e: I've updated gxlimg master branch. Now you should have enough to extract all you need to recreate a image from that
<_49616e>
Thank you, I'll give it a shot right now.
<_49616e>
> the bl30 I get also includes bl301?
<_49616e>
So the bl30 I got *doesn't* include bl301?
<repk>
yes it depends the board
<repk>
the one you have have a separate entry for bl301
<_49616e>
Good to know. What does "FIP" stand for by the way?
<_49616e>
repk: gxlimge doesn't seem to be able to merge bl301 back yet :)
<_49616e>
Since I can't decrypt bl301 with this tool yet, I can't use blx_fix.sh from amlogic to generate a new boot image either.
<_49616e>
s/boot image/bl30_new.bin
<repk>
yes I'm doing that right now :)
<repk>
its comming in a few sec

you can decrypt it can't you ?

_49616e:^
<repk>
at least I am able to it
<repk>
+do
<_49616e>
Oh, I didn't understand the help text correctly. Should I use bl30 or bl3x for the type?
<repk>
bl3x
<repk>
_49616e: I've pushed support for bl301, can you try that it boots with both "gxlimg -t fip --bl2 bl2.sign --bl30 bl30.enc --bl301 bl301.enc --bl33 bl33.enc emmc-boot.bin" and the one without bl301.enc but with a bl30 that you got merged with blx_fix.sh ?
<_49616e>
Sure, it'll take a moment though, please be patient :)
<repk>
Sure thx
<_49616e>
The image generated with gxlimg itself (with encrypted bl301) works great.
<_49616e>
*as in "mainline u-boot could start properly"
<repk>
ok perfect
<_49616e>
I can't seem to decrypt the bl30.enc with `gxlimg -t bl30 -d bl30.enc bl30.bin`
<repk>
bl3x
<repk>
s/bl30/bl3x/
<_49616e>
Ah, that worked. What's the bl30 type for then?
<repk>
Thats a type thanks
<repk>
well my bad bl30 has a different signature scheme than bl301
<repk>
but for other boards, like g12a. See README.g12a if you are curious
<_49616e>
Ah, so the bl30 type is for g12a, not gxl?
<repk>
yes that is correct
<_49616e>
Maybe consider updating the readme to make it clear :)
<repk>
There is no mention to bl30 type in README
<repk>
only in README.g12a
<_49616e>
> the one without bl301.enc but with a bl30 that you got merged with blx_fix.sh
<_49616e>
This one doesn't seem to work, I'm getting boot loops. It stops at `[0.xxxxxx Inits done]`
<repk>
Ok maybe your board does not support a merge bl301 then
<_49616e>
Still, I got to run mainline u-boot on my boards now thanks to you :)

<_49616e>
I'll try these on some S905D stuff I've got soon.
<_49616e>
Do you think it's a good practice to keep everything other than bl33 stock? That's what I intend to do for all of the tvbox type boards.
<repk>
you could also use opensourced bl31
<_49616e>
Yeah, I've tried that and 4 out of the 8 available cores failed to start on S912 :P
