The Jetson AGX Xavier 32GB module part number is P2888-0004.

I check the L4T Archive, and L4T R32.3.1 ~ R32.4.4 could support Jetson AGX Xavier 900-82888-0040-000 (with 32 GB memory)
https://developer.nvidia.com/EMBEDDED/linux-tegra-archive

I have some question:
Q1.Which DTS file for P2888-0004?
I can’t see any tegra194-p2888-0004-* in kernel source in L4T R32.3.1.

Q2.How to flash image for Jetson AGX Xavier 32GB? Is the parameter same as Jetson AGX Xavier 16GB?
./flash.sh jetson-xavier mmcblk0p1

hello SammyChenTw,

it’ll parse board information, but there’s no dependency of device tree file.
if you looking into Xavier’s flash configuration file, p2972-0000.conf.common
it’s using same DTB_FILE=tegra194-p2888-0001-p2822-0000.dtb; for flashing.
for example,
here’s Xavier-8G

$ cat /proc/meminfo | grep MemTotal
MemTotal:        7957412 kB

$ dmesg | grep DTS
[    0.432830] DTS File Name: /dvs/git/dirty/git-master_linux/kernel/kernel-4.9/arch/arm64/boot/dts/../../../../../../hardware/nvidia/platform/t19x/galen/kernel-dts/common/tegra194-p2888-0001-p2822-0000-common.dtsi

and… Xavier-32G.

$ cat /proc/meminfo | grep MemTotal
MemTotal:       32684728 kB

$ dmesg | grep DTS
[    0.438016] DTS File Name: /dvs/git/dirty/git-master_linux/kernel/kernel-4.9/arch/arm64/boot/dts/../../../../../../hardware/nvidia/platform/t19x/galen/kernel-dts/common/tegra194-p2888-0001-p2822-0000-common.dtsi

so, you may use the same flashing commands as your Xavier-16GB to flash Xavier-32G.
thanks
