[REGRESSION] Verdin AM62/62P not booting with 42b3ee7fa524

[REGRESSION] Verdin AM62/62P not booting with 42b3ee7fa524

[Francesco Dolcini]

Verdin AM62 and AM62P are not booting anymore with U-Boot 42b3ee7fa524,
everything was fine with b5213bbfdcb1.

Looking at the commits between the two revision, I would say that the
issue is with this series https://lore.kernel.org/all/20260127081652.506357-1-s-joshi@ti.com/

Suhaas: Can you help?

We have also commit 3382d75f7a6c ("arch: arm: dts: k3: refactor common
nodes to k3-*-r5.dtsi") that might be the root cause for this issue.

Hi Francesco. Unfortunately, I don't have Verdin line of boards with me,
so I cannot reproduce this issue. This is also why I wasn't able to test
my series on my end and had requested board-specific maintainers do the
same.

Since I don't have the boards, could you run the following test to help
us ascertain which of the 2 suspected commits actually broke the boot?

* First drop my AM625 Verdin patch, and compile and copy the binaries,
  and boot.
* Then let my patch remain in the tree, and remove Anshul's refactor
  patch, and try the same thing again.

This could help us ascertain which commit broke boot, and we can try
fixing from that commit.

Thanks
Suhaas

Sure, I can bisect it. 

Do this difference in the logs

Failed to set clock rates for '/a53@0': -22

  vs

Failed to set clock rates for '/a53@0': -61

ring any bell?

The boot failure start with commit 2ffab9da9142 ("Merge patch series
"Firewall ATF and OP-TEE memory regions in Sitara"").

With commit 24338c81ec2f ("arm: dts: k3-binman: Use configs for
ATF/OPTEE addresses") the board still boots fine.
I have some concern that this commit is changing something, however
CONFIG_K3_ATF_LOAD_ADDR is 0x80000000, while before in the dtsi file it
was 0x70000000. I tried changing it back without any positive result,
I just got an EL3 exception.

Any more test I should do?

Should I revert that firewall series, at this point?

I did one more test.

It seems that the issue is some interaction between the firewall series
and commit 24338c81ec2f ("arm: dts: k3-binman: Use configs for ATF/OPTEE
addresses").

If I keep the firewall series in, and revert 24338c81ec2f, it boots.

IMO, unless we understand what is going on exactly, we should revert
both.

That's the first part of the series, and to be clear I'd revert the
whole series.

These changes boot and some pytests run on am64x_evm_a53, am62x_evm_a53

This series is confirmed to be working on TI boards. I just tested it
(again) on AM62 SK. See [0] for logs.
Verdin boards are the only ones that are reporting this issue. Is it
alright if we revert only the two Verdin-specific commits, and let the
rest (TI and PhyCore ones) stay as they are? The patches are pretty
un-connected to each other.

We are working on figuring out why Verdin is seeing these issues, in the
meantime.

The phycore-am62x boots, see the logs

Yes, this is also new on verdin am62. It seems unrelated, and it should
be also be fixed / investigated.

Do you mind copying a boot log to a pastebin for me? I thought I had one 
of these boards but I'm still digging around for it. 0x80000000 should 
be where we load TFA now days unless some boards have opted out of 
letting U-Boot move it to the bottom of DRAM

Here some more logs

https://gist.github.com/dolcini/aa4b669c6349cc6da1b9e7b19cf53fed

The files are named with the commit sha that is tested.

Verdin AM62 should not have anything special, the code is all there for
everyone to see, including the defconfig, the DT and so on, and the changes
we are talking about to me are self contained withing the SoC. Something
is wrong, and we are not understanding what yet.

I just retested once more 42b3ee7fa524 and it just hung, you never know
if I did something wrong. And for what matter this was spotted by our
CI.

Anything I can do let me know.

If it matter the board that I am currently testing has 1GiB DDR RAM, and
the SoC is a AM6252ATCGHAALW.

I was able to trace the issue to the get_ram_size() in
verdin-am62.c:dram_init().

That function walks the addressable memory range to dynamically detect
how much memory is available.

Not sure on the proper way to fix it however, Bryan? Suhaas?

Yes, this does seem to be the issue, even in my digging. I have sent a
patch to fix this. But since I don't have boards, I have not tested
this. Could you please test this and let us know if it works, or if
there are any other issues that pop up?

Thanks

With commit f9ffeec4bdcf ("board: toradex: Make A53 get RAM size from DT
in K3 boards") merged we had our CI running on our whole board farm
last night.

Good news: the issue is confirmed to be fixed on Verdin AM62P and Verdin
AM62 [Quad|Dual] with [1|2]GB RAM.

Bad news: we we do still have a boot failure regression on Verdin AM62
single core with 512MB RAM. I have no idea if this is the same issue or
a different one, but from the logs it look different (despite that I
decided to keep using this email thread and not start a new one).

The failing board from the logs uses a AM6231ASGGHAALW SoC, maximum
frequency 1GHz, we also have another device failing, single core again,
with maximum frequency 800MHz, the working one have 1.4GHz max
frequency.

Worth noticing the errors
  Failed to set clock rates

These are new compared to the previous U-Boot release, it affects also
other boards, and I have no idea if this is related to this issue or not.

Unfortunately I do not have a single core board to test readily
available now, and I will be out of office a couple of days, but
I decided to share this immediately so that we can try to understand
what's going on. Middle of next week I should be able to do more tests.

I don't think this one is related to the firewall series. Not really
sure what the issue is. Just to rule this series out -- could you drop
my patch(es) and check if this specific device boots?

Was this device booting earlier? Could it be a build misconfig, since it
says that it can't detect an image signing certificate?

This is a regression with 2026.04. 2026.04-rc never booted on this device, and
before commit f9ffeec4bdcf1da655a0ffea482062adde78fee8 none of the verdin
am62[p] variants were booting for multiple bugs that were present in the
release.

2026.01 is booting fine on this device, with plain vanilla U-Boot.

The issue is still there, and it seems again related with your changes.

Can you help? Any test that I should do?

I'm suspicious of the spl_enable_cache(). I've witnessed issues if we 
add MMU entries that are not backed by DRAM which can cause the MMU to 
crash the CPU.

I wonder (complete guess right now) if we're passing the correct DRAM 
density to the A53 SPL?

I have sent out a fix patch to drop the a53 clock overrides from the 
board files, 
https://lists.denx.de/pipermail/u-boot/2026-February/610466.html

With that fixed the boards will now show

   Set clock rates for '/a53@0', CPU: 1250MHz at Speed Grade 'T'

I looked into that function.

This is my current theory:

The end address of 512MB RAM is 0x9FFFFFFF. This is the same as OPTEE's
end address.

If you look into the `spl_enable_cache()` function, you'll see that it
is subtracting the size of page tables from the top of RAM, i.e. it is
placing the page table at the end of RAM, i.e. it is placing the page
table in OPTEE's memory region. Since this region wasn't protected by
firewalls earlier, everything worked. But now the firewall disallows
U-Boot's access to the page table.

On 1GB and 2GB devices, there's a great deal of distance between the
end addresses of RAM (0xBFFFFFFF and 0xFFFFFFFF respectively) and the
end address of OPTEE. So we don't run into this issue.

Francesco -- Just to confirm if this indeed is the case, could you
change CONFIG_K3_OPTEE_LOAD_ADDR to any other free location, and check
if the device boots?

Ah so for our am62 SiP package (which also has 512MB of DDR) we ended up 
moving OP-TEE down to 0x80080000[0] to let U-Boot relocate itself 
without crashing into OPTEE or TFA

Because tiboot3.bin starts off the main domain by sending the A53 to  
TFA -> OPTEE -> SPL there isn't a great way to pass along the info to 
TFA on where to go next at run-time.

So for this to work we will need to adjust the jump defaults in both 
TF-A and OP-TEE as well as modify the K3_OPTEE_LOAD_ADDR here.

We're doing this in yocto here[1][2]

[0] https://git.yoctoproject.org/meta-ti/tree/meta-ti-bsp/conf/machine/am62xxsip-evm.conf#n7
[1] https://git.yoctoproject.org/meta-ti/tree/meta-ti-bsp/recipes-bsp/trusted-firmware-a/trusted-firmware-a-ti.inc#n29
[2] https://git.yoctoproject.org/meta-ti/tree/meta-ti-bsp/recipes-security/optee/optee-os-ti-overrides.inc#n9

With that updated it should allow us to get past the TFA init

Though this all assumes we're expecting OP-TEE init prints here and the 
board reset's itself after sometime because a watchdog went off.

Some progress ...

I had to review also the U-Boot configuration, the whole memory map must
be revised ...

With that sometime it works ...

It's quite a pain. I will review the complete memory map and check if I
missed something.

Bryan: I think TI should consider having both OP-TEE and TFA at the
beginning of the memory on any AM62* SOC by default, this would just be
the most robust way to have something working no matter the amount of
memory that is fitted.

How strange. It's odd U-Boot on some boots finds a certificate with the 
binaries and on others attempts it does not. If the image inside the 
tispl.bin was corrupted I would expect the SPL to reject the image.

I'll start bothering Andrei for some of your hardware :)

Completely agree. 

The BeagleBoard people went through this pain a few weeks ago for the 
Pocketbeagle2 boards. It's a problem.

Originally we envisioned DRAM density would go up just like with flash 
densities as the SoC's matured. Obviously this isn't happening

It might be worth finding a way to move them (or change their default 
locations). I'll start pestering people in TI to get a plan in place.

Some more updates ...

I was not able to verify this yet, but it seems that since commit
ba20b2443c29 ("arm: mach-k3: common: Reserve video memory from end of
the RAM") the ram top is overwritten and our
verdin-am62.c:board_get_usable_ram_top() is ignored :-(

So, the change from devarsh broke it, but before the addition of the
memory firewall the memory corruption was not leading to a crash ...

Please verify this, because it is as well possible that I am completely
wrong.

Thanks
Francesco

Some small progress.

I can confirm that the issue is around the board_init_f() that is
overridden on the k3 architecture and spl_enable_cache(). It messes up
with gd->*ram* variables ignoring various config options, including
verdin-am62.c:board_get_usable_ram_top(). Any comment on this?

Trying to get out of this regression, one solution would be to move the
whole memory map as it was done on the pocket beagle2, as it was
suggested a few email ago.

Or fix the spl_enable_cache() implementation.

Bryan, and TI folks, what's your suggestion on the next steps here?

In addition to that, no matter if I do a quick and dirty hack on
spl_enable_cache(), or if I move the optee at the beginning of the ram,
I get this error once every few resets

```
...
Authentication passed
Authentication passed
Loading Environment from nowhere... OK
init_env from device 9 not supported!
Warning: Did not detect image signing certificate. Skipping authentication to prevent boot failure.
This will fail on Security Enforcing(HS-SE) devices
```

and after that a freeze. I am starting to think that this is another,
unrelated issue.

Thanks for the support,
Francesco

Thanks for sharing this information, maybe I missed out handling the
board_get_usable_ram_top scenario in my original patch.

For this particular problem, could you please try with  "[PATCH] arm:
mach-k3: common: Clamp RAM end address to board-usable region in
spl_enable_cache()"

that I sent over the list/email and let us know if it helps solve above
problem ?

Yes, I can confirm that this is another, but related issue :-/

There is a memory corruption, something not ok in get_ram_size(), cache
related, that is leading to a memory corruption and therefore these
random crashes.

For some reason the memory corruption is happening calling dram_init()
twice and with 512MB module and with commit cb41b7c83444 ("board:
toradex: Make A53 get RAM size from DT in K3 boards"), I did debug this
with plain v2026.01 + cb41b7c83444.

This https://lore.kernel.org/all/20250314100734.23777-1-eichest@gmail.com/
solves the issue, but it was not applied when it was first sent months
ago.

Tom: you were the one with some concern, from my point of view we
should just apply it, any concern?

On the other topic I am waiting for TI advise if they plan to fix
spl_enable_cache() or I would need to work on revising the memory map
for the various firmwares + U-Boot.
