uLoadXL™ Secure Boot and Installer


The uLoadXL SDK delivers advanced secure boot loader and software update solutions for embedded platforms. uLoadXL can manage software updates and distribution, encrypt images, authenticate genuine origin, and block malware.

The WSLAM Windows GUI signs and encrypts the system image using key material and user-supplied private activation code. Secure managed images can be transferred by email, flash drive, serial port, or OTA LAN/WAN network.

To install the software update on the embedded platform, the activation code is supplied to the loader interactively or under machine control.

The installer decrypts and authenticates the system image and saves it to the target program flash.

An incorrect activation code or a malware image is blocked from installing and executing

At power up or reset uLoadXL executes system integrity checks, verifying application signature with configurable fallback and recovery steps.

Platform Kit. uLoadXL APIs are interfaced to the embedded target via integrated Platform Kit including standalone drivers for internal MCU flash, external QSPI flash, removable media, and serial I/O channels.

Multiple Images. The uLoadXL embedded system and APIs can manage mutiple images. Workflow can be programmed to install, save, and activate A/B image firmware and auxiliary files.

Registry. Loader maintains image registry information inculding status and authentication signatures. System application is verified before starting execution to detect corrupt image or malware intrusion attempt.

Security Model. uLoadXL implements an advanced key system, selectable cipher suite, code sign and verify, and protected embedded key material container with anti-rollback protection

Robust. System integrity, safety, and availabilty features include primary and backup registry copies, power fail recovery, primary and recovery image, and failsafe options.
