[Orin NX 16GB] DRAM sku change Micron => hynix

[joe.zhang]

Hi there,

L4T version:35.3.1: tweak DRAM sku from L4T 36.4.0

We recently encounter a great problem, the Orin NX 16GB from our vendor swap the DRAM sku without notifying.

Lead to flash qspi failed:

Cleaning up...

From Micron => hynix.

Micron: old one : pass

Board ID(3767) version(300) sku(0000) revision(L.2)
Chip SKU(00:00:00:D3) ramcode(0) fuselevel(fuselevel_production) board_FAB(300)

Hynix: new one: failed

Board ID(3767) version(301) sku(0000) revision(G.1)
Chip SKU(00:00:00:D3) ramcode(1) fuselevel(fuselevel_production) board_FAB(301)

In theory, the L4T35.3.1 could change some DRAM related binary to perform this, since “L4T36.4.0” can bring up both of them.

I would say this was pretty urgent since we got the SOM after the customer order.
And we have no time to porting L4T 36.4.0 onto out product.
We can’t update the qspi version only either (can’t boot into L4T35.3.1 rootfs/OS).

Please let me know what to change.

THANKS~~
Joe

please check l4t archive page if it has the PCN overlay. If there is not, please contact your NVIDIA contact window for it.

I know the L4T 35.6.1 will fix this issue:

Jetson Linux

And found the ‘PCN 211361’ note.

If this topic was right, the L4T 35.2.1 has the patch for it around 2024-10, maybe all of the version has it’s patch.

JetPack 5.1 support for Sk Hynix and Samsung Memory

We are currently flashing using flashing files from JetPack 5.1, we want to include patches for PCN209760 and PCN211361 (inclusion of support for SK Hynix DRAM memory and Samsung DRAM memory), can nVidia provide the patching files for us so we can continue to use our original flashing Jetpack versions? We are producing in a mass-production enviroment and cannot update the rootfs to a new linux-for-tegra release. Jetpack 5.1.4 is the earliest release that supports both PCNs, if we use the fl…

But our vendor had a hard time to ask the upstream-vendor what the patch is.
To speed up the process, can you provide the related name of the patch for them to search?
Or you can give it to me directly, I will be appreciate.

THANKS~~
Joe

We don’t provide the overlay on forum.

[joe.zhang]

Can you provide link to download center or document?

[joe.zhang]

The overlays only contains bootloader of L4T.

So the migrate is quite smooth once we get the patch.

Additional, can we get the difference between Micron and Hynix DRAM only via USB recover device and without enter the ‘RCM-boot’ ?

Not possible.
