orangepi zero3

orangepi zero3

[Stephen Graf]

I have been able to build a working (on my orangepi zero3 1G) u-boot for 
the orangepi zero3 with the following defconfig. Would it be possible to 
add this config to the working boards.  I would test it again with an 
official build. The dtb/dts is in linux and in u-boot.

The H618 processor is software compatible with the H616 and the zero3 
board is very similar to the zero2 with the exception of DDR3 replaced 
with LPDDR4 and the Realtek phy with Motorcomm.

thanks for your interest in contributing and for reaching out!
As Peter already mentioned, you would need to send a patch, as generated
by "git format-patch". "git send-email" would help you with sending this
out.

But actually I sent a small series already last week:
https://lore.kernel.org/u-boot/20231114013106.31336-1-andre.przywara@arm.com/

If you could apply these patches and test it on your board, I'd be
grateful. If it works for you and you are happy, please reply to patch 3/3
and add a "Tested-by: Your Name <your@email.com>" line.
For instructions how to reply, check "Reply instructions" at the end of
that mailing list archive web page above.

I was just waiting for confirmations by other people before merging it.

Cheers,
Andre

Thanks for coming back. Please keep the list(s) on CC:, as this is also
interesting for others, and more eyes help to find issues faster.
CC:ing Piotr and Mikhail, who were debugging the LPDDR4 DRAM setup
before.

Ah, that's a good report! I actually saw the same issue (reporting 8GB
instead of 4GB), and my hunch is that it's related to some missing
barriers or delays, as seen on other boards.
Can you try to add a "dsb();" to the beginning of
arch/arm/mach-sunxi/dram_helpers.c:mctl_mem_matches(), before the first writel()?
I am still not convinced this is the right place to put the barrier,
but it would confirm that this is the issue.
Also I didn't see this effect consistently, so did this happen for you
every time?

Another thing you could try is to increase the voltage to 1150mV, this
is what Piotr needed for reliable operation.

Yeah, I saw this, and I hope we can avoid this. I am not sure if you
are the first one with a 1GB board, so your testing is definitely
helpful.

(please use "diff -u", that's easier to read and people are more used
to its output style)

I don't think those minor timing differences matter much, but you can
try to experiment with both set of values.

Not specifying DRAM_CLK means it uses the default 720 MHz. In the past
lowering the DRAM frequency was an easy way to stabilise the DRAM
setup, even though this might somewhat paper over other issues.

Please double check, but I think all new OrangePi boards now use a zBIT
flash chip? Should have a small "Z" like logo on that 8 pin chip with
the large pins on top.

1100mV is the default, so putting exactly this value in doesn't change
anything.

> < CONFIG_CMD_BOOTZ=y

Why do you need bootz? I don't think this doing anything useful in
mainline U-Boot. Don't know if OrangePi was just confused and had an
actual use case for this.

There is a pending patch for mainline Linux, can you try to apply those
DT changes to U-Boot's DT copy and see if that helps?

Re: orangepi zero3

[Stephen Graf]

I tested a u-boot build with the emac timing changes you pointed out and 
with CONFIG_DRAM_CLK=792. It looks like this configuration and dts 
changes works with both 100Mb and 1Gb switches.

I am struggling to get something to actually load. Is there an easy way 
to get a debian image onto the sd card so that u-boot can actually load 
something.

Ah, great, thanks! I will see if I can pull the DT change in sometime
soon.

Userland wise you can use any arm64 image, for instance any of the
cloud images, or you nick it from some existing arm64 installation.
Kernel wise the only requirement would be at least a v6.5 kernel, since
only this one supports the Motorcomm Ethernet PHY and, more
importantly: the PMIC.
Any distro kernel would do, or you bake your own, defconfig should be
enough for booting plus USB and MMC. CONFIG_DWMAC_SUN8I=y and
CONFIG_MOTORCOMM_PHY=y should give you Ethernet on top, I think, but
there might be more needed.

For a quick boot, set the commandline and load and boot the kernel:
=> setenv bootargs "console=ttyS0,115200n8 earlycon root=/dev/mmcblk0p2 rootwait"
=> load mmc 0:1 $kernel_addr_r Image-6.7-rc2
=> booti $kernel_addr_r - $fdtcontroladdr

(those are rough instructions, please fill the gaps, or reply with specific questions)

You could even try to install a distro, using the official UEFI
installers many distros provide. This process can be long and
tedious, though, plus you need a v6.5 installer kernel, and would
probably need to play around to get it booted automatically.

> Console output:

This seems to got mangled, but looks like expected: you just have
nothing that would load automatically. A USB stick with an UEFI boot
program should be detected and started, for instance a distro
installer. Still you would need a v6.5 kernel, without the PMIC driver
you won't get far.

Cheers,
Andre

P.S. You can put the whole firmware (U-Boot + TF-A) on the SPI flash,
that gives you more freedom with the SD card. Just follow the
instructions in doc/board/allwinner/sunxi.rst.

I tried using an additional barrier as you described:

diff --git a/arch/arm/mach-sunxi/dram_helpers.c 
b/arch/arm/mach-sunxi/dram_helpers.c
index cdf2750..16938fa 100644
--- a/arch/arm/mach-sunxi/dram_helpers.c
+++ b/arch/arm/mach-sunxi/dram_helpers.c
@@ -34,6 +34,7 @@ bool mctl_mem_matches(u32 offset)
  {
      /* Try to write different values to RAM at two addresses */
      writel(0, CFG_SYS_SDRAM_BASE);
+    dsb();
      writel(0xaa55aa55, (ulong)CFG_SYS_SDRAM_BASE + offset);
      dsb();
      /* Check if the same value is actually observed when reading back */

After this I did not notice any problems with incorrect configuration.

As I understand it, the problem occurs most often during a hot plug.
