To: barebox
I have spent the last couple of days trying to port our bootloader
from u-boot to barebox 2020.07 but have yet to get any console output.
Our product is based on tqma7d i.MX7 dual core cpu and uses UART4 for
serial console and boots from internal eMMC.
I created a new board inspired from "NXP i.MX7 SabreSD board" and
tried to only add the basic in the first step to get a console output
working. The image is built using ptxdist and the imx_v7_defconfig
where the new board is selected. The image is flashed with "dd
if=barebox-image of=/dev/mmcblk0 bs=1024 skip=1 seek=1 conv=fsync".
The device works using u-boot 2020.07 with the same device trees but
we thought it was time to try out barebox since u-boot felt a little
bloated :)
So can anyone be of assistance and tell me what I'm missing?

The DCD part now matches exactly for the top part (00000000 to
00000020) of it which i guess is the IVT header, which shouldn't be
the same?
The following is xxd where barebox (left side) has been shifted 0x400
to match u-boot part.

Enable CONFIG_DEBUG_LL and see how far barebox comes.
See the inline comment from my last mail.

Thanks for the quick response :) I have made some inline comments
Additionally I have fixed the __dtb_z_ unrelated issue, but still
troubles to get some output. Could you maybe send me a barebox binary
for an mx6 or mx7 board? I'm still unsure if it has the correct binary
format.
My current Kconfig values look like this. Maybe you can see something
missing.I have patched drivers/regulator/Kconfig (ARCH_IMX7) so that I
can enable REGULATOR_PFUZE, which is used on the tqma7d board. From
what I can see the NXP i.MX7 SabreSD board uses a PF3000 PMIC too so
iam unsure why it can work without this fix.

I don't think u-boot does something extra in c code, but i'll check
again. The board config in u-boot is stripped down so that it only
probes info through the device tree.
And the DCD table is exactly the same in the compiled output.

I missed some of the last comments but I have already enabled
CONFIG_DEBUG_LL and can't get any console output to appear. UART4 has
been selected in the menu for this.

Can you not compile a i.MX7-EVK barebox and run it on the EVK?
If this doesn't work, this is a different issue.

Then that's what you need to focus on. Prior to that '>', not much
code has run. If you don't come that far, chances are you set up your serial port
wrong (looks correct to me though) or your DCD table is wrong...

Thanks for the feedback.
I will order an i.MX7 EVK board and try to get it working. I guess
that we were a little too confident that the TQma7d board would work
out of the box with only minor tweaks.

This config still has CONFIG_DEBUG_IMX_UART_PORT=1. You probably sent
this before you changed it to '4', right? Otherwise this might be the
issue.

When I looked through your patch the first time, I just looked
for stuff that would cause it to not boot. Some more comments
inline that are unrelated to your boot problems.

Function serves no purpose. If you don't have baord code, drop it altogether.

Perfectly fine for your patch stack in BSP, but if you want to upstream
it, you need to either:
1) upstream your device tree to Linux. dts/ is a sync with Linux and
shortly after, it will be imported into barebox
2) put your device tree in arch/arm/dts

Hi.
I just go an MCIMX7SABRE board and it now trying to start barebox from
the external SD card, which I guess should be possible right?
I have taken barebox 2020.07.0 and copied the imx_v7_defconfig and
deselected all boards except the "NXP i.MX7 SabreSD board"
After compilation i copy the image using:
sudo dd if=barebox-freescale-mx7-sabresd.img of=/dev/sdb bs=1024 skip=1 seek=1
sync
But still no boot screen for that either. :/
Shouldn't this work out of the box??

Works for me.
imx_v7_defconfig
OSELAS.Toolchain-2019.09.1
Image written to SD card (offset 0) and booted from.
Can you try with same toolchain? If that works, it
might be a compiler issue? What are you using?

I'm using 2019.09.1 toolchain too. When you are saying "offset 0" is
that the same as nuking the MBR on the sd card? Like the following?
sudo dd if=barebox-freescale-mx7-sabresd.img of=/dev/sdb bs=1024
Okay I think that I have found the issue:
If are buldiing all the boards selected by the imx_v7_defconfig I get
an much bigger image size:
All boards selected (657570 bytes)

A lot of stuff gets deselected, since the board doesn't depend on it.
Stuff like: CONFIG_MCI_IMX_ESDHC_PBL is suddenly not enabled, which I
think is vital. So I'll test the it tomorrow

Yes, that's what I did (or rather labgrid write-image did for me)

That's expected. multi-image means that barebox is built to support
multiple boards and multiple images are generated, one for each board.
These images share the same main barebox, but each have a different
pre-bootloader (and device tree). Only the board code and drivers
matching the device tree are executed. The rest should remain
unused by your board.
To make sure this does work as intended, I just built barebox with
only barebox-freescale-mx7-sabresd.img selected and it works fine for me:

It's not. When you do your SDRAM setup in DCD, you can have the ROM code
load barebox directly into SDRAM, so there's no need to have a limited
eSDHC driver in pre-bootloader. CONFIG_MCI_IMX_ESDHC_PBL is unset then.
Are you sure the board is strapped correctly to boot from SD?

I got the board configuration as:
SW3 = 10
SW2 = 00100000
I have tried with:
cat barebox-freescale-mx7-sabresd.img > /dev/sdb
sync /dev/sdb
and
sudo dd if=barebox-freescale-mx7-sabresd.img of=/dev/sdb bs=1024

Oh. Can you turn them off stepwise to see, which config option

I skimmed through your config,
-CONFIG_RELOCATABLE=y
+# CONFIG_RELOCATABLE is not set
CONFIG_TEXT_BASE=0x0
Text base is ignored, when you are relocatable. If you aren't relocatable,
you need a valid address as your text base. Why did you turn it off?
Cheers,
Ahmad

Hi. I also got it working with a single board compilation now.
You are correct that it is the CONFIG_RELOCATABLE that is the issue.
If I select this it works.

I didn't turn it off. It isn't selected by MACH_FREESCALE_MX7_SABRESD
so it gets turned off if only this board is used. It is selected by 6
other boards, which is the reason it works when compiling for all
boards.

I don't think that's how it works. If it was =y and the select went
away because of CONFIG_MACH_CCMX51=n, it remains at =y. I just tested
it and that's the behavior I observed.
I am not sure what we could do better here. You can use barebox
as non-relocatable binary if you set CONFIG_TEXT_BASE to a sensible
value. You might want this if you are keen on reducing barebox size
further at cost of portability. So having a select here to ensure
it's always set won't work.
We can also not set a suitable CONFIG_TEXT_BASE at Kconfig level,
because, due to multi-image support, we may be building different
boards with different TEXT_BASEs...
We could have RELOCATABLE be default y as it's a more sensible default
though. Sascha, what do you think?

If I use the imx_v7_defconfig and go and deselect "ConnectCore
i.MX51" (MACH_CCMX51), then RELOCATABLE will change from =y to =n
So in other words. Deselecting this one board (MACH_CCMX51) will set
RELOCATABLE=n and now all the boards rely on CONFIG_TEXT_BASE to be
set correct. And as you also mentioned later on, this will be an
issue.

That's strange. I can confirm what Ahmad said: starting from
imx_v7_defconfig and deselecting MACH_CCMX51 still leaves RELOCATABLE
enabled here. I have no idea why this is different for you.
Anyway, on i.MX a barebox binary with RELOCATABLE disabled only works in
very special cases and requires setting TEXT_BASE to a suitable value,
one that works on all boards selected. It would be nice to hide
RELOCATABLE from the user in most cases.
