Reflash Jemii-150 with SDKmanager

Basic Concept

1. Download and Install SDKmanager

2. Prepare an x86 Host Computer for Flashing

3. Connect the Host computer and Jemii-150

4. Put Jemii-150 into Recovery Mode

5. SDKmanager FLASH

1. Download and Install SDKmanager

NVIDIA SDK Manager download website: https://developer.nvidia.com/sdk-manager

Local repo:

• Download the install file for your desired platform

• Run the command for your desired platform:

  • Ubuntu: sudo apt install ./sdkmanager_[version]-[build#]amd64.deb

  • RHEL/CentOS: sudo dnf install ./sdkmanager[version]-[build#].x86_64.rpm

Network repo:

From a terminal window, run the following commands for your desired platform

Ubuntu:

wget https://developer.download.nvidia.com/compute/cuda/repos/[distro]/x86_64/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb
sudo apt-get update
sudo apt-get -y install sdkmanager
//Replace the highlighted distro with the one that you are using. Supported distros are: ubuntu1804, ubuntu2004, ubuntu2204, ubuntu2404

RHEL/CentOS 8.2:

sudo dnf config-manager --add-repo https://developer.download.nvidia.com/compute/cuda/repos/rhel8/x86_64/cuda-rhel8.repo
sudo dnf clean all
sudo dnf install sdkmanager

2. Prepare an x86 Host Computer for Flashing

Prepare a host computer that meets the following system requirements

• x86 architecture

• Check the Host Computer Ubuntu version which decides the target JetPack version and other NVIDIA SDK you could flash (check below matrix table)

• at least 8GB Memory

• at least 120GB Storage

3. Connect the Host computer and Jemii-150

Connect the host machine with Jemii-150 via a USB type A (on Host Machine) to type C (on Jemii-150) cable

4. Put Jemii-150 into Recovery Mode

We have designed two methods to put Jemii-150 into recovery mode.

Method A: Recovery Button For Development (Requiring Disassembly)

Steps:

1. Hold down the recovery button first

2. Connect Power Cable with ATX power/Terminal Block to power on

3. Wait for 5 second

4. Release the recovery button

Recovery Button From the top-view, you could find the recovery button which locates ???

ATX power/Terminal Block

Method B: Press Power Button First (No Disassembly Required)

Steps:

1. Connect PIN 1-2 of PMS pin header (select Power Button mode)

2. Connect PIN 5-6 of SYSTEM_PANEL pin header (power button pin header and GND)

1. Connect Power Cable with ATX power/Terminal Block to power on

2. Put Jemii-150 into recovery mode

SDKmanager FLASH

Check if Jemii-150 put into Recovery Mode

If Jemii-150 is ready to be flashed, you will see Jemii-150 listed as a USB device after do the command

lsusb

SDKmanager Flash From a terminal window, launch SDK Manager with the command:

sdkmanager

(Remember to register an account for NVIDIA Developer to use SDKmanager)

For older SDK versions run:

sdkmanager --archived-versions

SDKmanager FLASH

You could check your Orin module and select the target JetPack version.

After set up process, you would finish sdkmanager flash
