Toradex Verdin AM62 boot failure on recent master

Toradex Verdin AM62 boot failure on recent master

[Vitor Soares]

Hi,

I'm experiencing a boot failure on Toradex Verdin AM62 with the latest master.
The last known good commit is a4dc1c3b7d56 and it fails to boot at 64662b99c0eb
(current HEAD).

Looking at the 35 commits in this range, I noticed that the first commit after
my last known good is 85f586035d75 ("ARM: OMAP2+: Pad SPL binary to 8-byte
alignment before DTB"), which directly modifies the K3/AM62 SPL linker script.

Related commits:
  85f586035d75 ARM: OMAP2+: Pad SPL binary to 8-byte alignment before DTB
  8b0ebe054bb3 arm: Update linker scripts to ensure appended device tree is
aligned

Could these changes be related to the boot failure? Any insights would
be appreciated.

Thanks,
Vitor Soares

Does reverting 8b0ebe054bb3 ("arm: Update linker scripts to ensure
appended device tree is aligned") make the board boot again?

I noticed that this commit broke the boot of a Rockchip board:

https://lore.kernel.org/u-boot/CAOMZO5CLQZ3i+Eit5csv6E+az-_g2eOHfCr-whQTPeg06WtqEg@mail.gmail.com/

In the failing boot case, do you get any SPL message at all?

The v3 patch alone didn't fix the boot issue on Verdin AM62.

However, Marek's suggested approach [1] that only aligns flat_dt type
images to 8 bytes does fix it:

diff --git a/tools/fit_image.c b/tools/fit_image.c
--- a/tools/fit_image.c
+++ b/tools/fit_image.c
@@ -685,6 +685,13 @@ static int fit_extract_data(...)
              const char *data, *type;
              int len;

+             /* Ensure flat_dt images are 8-byte aligned per DT spec */
+             if (align_size < 8) {
+                     type = fdt_getprop(fdt, node, FIT_TYPE_PROP, &len);
+                     if (type && len > 0 && !strncmp(type, "flat_dt", len < 8 ?
len : 7))
+                             align_size = 8;
+             }
+
              data = fdt_getprop(fdt, node, FIT_DATA_PROP, &len);

+Cc Fabio - this should resolve your boot failure as well.

Thanks for the suggestion, but this does not fix the boot failure on RV1103.

Tom's proposal fixes it:
