                        <ul style="margin-left: 1.25rem;">
                            <li>Chrome 61+ (Windows, macOS, Linux)</li>

                </div>

                <h3 style="margin-top: 2rem; margin-bottom: 0.75rem;">How to Enter USB Boot Mode</h3>
                <p>To configure your device for USB boot mode:</p>
                <ol style="margin-left: 1.25rem; line-height: 1.6;">
                    <li>Power off your device</li>
                    <li>Set the boot mode switches according to your device's user guide (typically specific switch positions for USB boot)</li>
                    <li>Connect a USB cable between the device and your computer</li>
                    <li>Power on the device</li>
                    <li>The device should appear as a USB device in your system (VID:PID <code>0451:6165</code> for AM62x/AM64x)</li>
                </ol>
                <p style="margin-top: 0.75rem;"><strong>Note:</strong> Boot switch configurations vary by device. Refer to your device's Evaluation Module User Guide for specific instructions.</p>

                <h3 style="margin-top: 2rem; margin-bottom: 0.75rem;">Upload Process</h3>
                <p style="margin-bottom: 0.5rem;">This tool implements the USB DFU (Device Firmware Update) protocol to upload bootloader images:</p>
                <ul style="margin-left: 1.25rem; line-height: 1.6;">
                    <li><strong>tiboot3.bin</strong> - Initial bootloader (uses alternate interface 0: "bootloader")</li>
                    <li>After tiboot3.bin loads, the device will present new interfaces for tispl.bin and u-boot.img</li>
                    <li>Upload progress is shown in real-time with transfer speed and completion percentage</li>
                    <li>The device may reset automatically after successful upload</li>
                </ul>
                <p style="margin-top: 0.75rem;"><strong>Expected behavior:</strong> After uploading tiboot3.bin, you should see the device reset and begin booting. Check your serial console for boot messages.</p>

                <div class="disclaimer-box" style="margin-top: 2rem;">
                    <h3 style="margin-bottom: 0.75rem;">⚠️ Important Safety Information</h3>
                    <ul style="margin-left: 1.25rem; line-height: 1.6;">
                        <li><strong>Device Compatibility:</strong> Ensure you are uploading the correct bootloader for your specific device model</li>
                        <li><strong>File Integrity:</strong> Only use official TI bootloader images or images you have built from verified sources</li>
                        <li><strong>Power Stability:</strong> Do not disconnect the device or interrupt power during upload</li>
                    </ul>
