JP 6.2: Unrecognized module SKU 0005

[paroque28]

Hi guys,

I got this error today, do you guys have any idea what SKU 0005 is? And why is it not supported?

Board ID(3767) version(300) sku(0005) revision(N.1)
Preset RAMCODE is 2
Chip SKU(00:00:00:D5) ramcode(2) fuselevel(fuselevel_production) board_FAB(300)
emc_opt_disable_fuse:(0)
Error: Unrecognized module SKU 0005
Error: failed to generate images
Cleaning up...

Thanks a lot,
Pablo

To be more specific I am trying to make tegra234-p3768-0000+p3767-0005-nv-super.dtb work

[paroque28]

FWIW,
I made this change for JP6.2:

update_flash_args_p3768_0000_p3767_0000()
{
	if [ "${board_sku}" = "0004" ]; then
		DTB_FILE=tegra234-j401-p3768-0000+p3767-0004-recomputer.dtb;
        elif [ "${board_sku}" = "0005" ]; then
		DTB_FILE=tegra234-p3768-0000+p3767-0005-nv-super.dtb; 
	elif [ "${board_sku}" = "0003" ]; then
		DTB_FILE=tegra234-j401-p3768-0000+p3767-0003-recomputer.dtb; 
	elif [ "${board_sku}" = "0000" ]; then
		DTB_FILE=tegra234-j401-p3768-0000+p3767-0000-recomputer.dtb; 
	elif [ "${board_sku}" = "0001" ]; then
		DTB_FILE=tegra234-j401-p3768-0000+p3767-0001-recomputer.dtb; 
	else
		echo "Error: Unrecognized module SKU ${board_sku}";
		exit 1;
	fi

	TBCDTB_FILE="${DTB_FILE}";
}

And I was able to boot my device, probably not 100% seeed studio compatible but it might help someone

HI @paroque28 with 6.2 do you able to turn on max power mode? Called super boost or something

[paroque28]

@deadmerc yes, I am able, but you need to create this file:

recomputer-orin-j401-super.conf

source "${LDK_DIR}/p3768-0000-p3767-0000-a0.conf";

update_flash_args_p3768_0000_p3767_0000()
{
	if [ "${board_sku}" = "0004" ]; then
		DTB_FILE=tegra234-p3768-0000+p3767-0004-nv-super.dtb;
        elif [ "${board_sku}" = "0005" ]; then
                DTB_FILE=tegra234-p3768-0000+p3767-0005-nv-super.dtb;
	elif [ "${board_sku}" = "0003" ]; then
		DTB_FILE=tegra234-p3768-0000+p3767-0003-nv-super.dtb;
	elif [ "${board_sku}" = "0000" ]; then
		DTB_FILE=tegra234-p3768-0000+p3767-0000-nv-super.dtb;
	elif [ "${board_sku}" = "0001" ]; then
		DTB_FILE=tegra234-p3768-0000+p3767-0001-nv-super.dtb;
	else
		echo "Error: Unrecognized module SKU ${board_sku}";
		exit 1;
	fi

	TBCDTB_FILE="${DTB_FILE}";
}

update_flash_args()
{
	update_flash_args_common
	update_flash_args_p3768_0000_p3767_0000
        p3767_super_overlay
}

PINMUX_CONFIG="tegra234-mb1-bct-pinmux-p3767-hdmi-a03.dtsi";
PMC_CONFIG="tegra234-mb1-bct-padvoltage-p3767-hdmi-a03.dtsi";
OVERLAY_DTB_FILE+=",tegra234-dcb-p3767-0000-hdmi.dtbo,tegra234-p3767-camera-p3768-imx219-dual-seeed.dtbo";
DCE_OVERLAY_DTB_FILE="tegra234-dcb-p3767-0000-hdmi.dtbo";

And then flash using:

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1   -c tools/kernel_flash/flash_l4t_t234_nvme.xml -p "-c bootloader/generic/cfg/flash_t234_qspi.xml"   --showlogs --network usb0 recomputer-orin-j401-super internal

@paroque28 thanks a lot

@paroque28
Have you done any stress testing on the MAXN SUPER power mode on your flashed device? I have an Orin NX and under heavy load, cannot force my device to go past 22W according to the Jetson power GUI. This is despite the fact that MAXN SUPER is the selected power mode, and supposedly allows the Jetson to run at up to 40W. It seems the GPU is still capping itself at the old max power limit.

Is the new power mode working for you? If it works for you, then it's probably an issue with my setup or maybe the way I am stressing the system, so I would love to know. Thanks in advance :)

[paroque28]

@dduuukk no it seems you are right :( I thought it was that easy

[bigbearishappy]

@paroque28 The SKU 0005 is the main board of orin nx 8g(specially for development kit) with jetson official carrier board.

[dduuukk]

@paroque28 Just fyi, the J401 cannot support super mode if you are using an Orin NX. seeed mentioned it here a little while ago.

The current J401is hardware limited to 5V VDD_SYS. I assumed that I could disconnect the VDD_IN plane for the Orin NX and supply it with boosted 8V at 5A while keeping the rest of the board at normal system voltage with a quick hardware mod. Unfortunately, even though the drivers suggest the max input current now 5A @ 8V with this configuration, I couldn't get it to pull more than ~22W. Super weird.

Probably best to wait for the new hardware revision or buy an official carrier board when they come back in stock :/
