LinRT Helium BSPs optimized for i.MX platforms
LinRT Helium, Oxygen, Mercury and Cobalt Yocto BSPs are based on Yocto Rocko 2.4.4, Yocto Thud 2.6.4 and FSL Community BSP in order to provide support for i.MX based platforms and include official Linux kernel stable updates, backported features and fixes coming from LinRT, vendors, kernel community or FSL Community itself. It includes support for many IPs such as GPU, VPU and IPU for i.MX series processors.

LinRT proposes two solutions for GUI interface Framework, one with support with i.MX multi-framebuffer FSL Community/NXP’s BSP approach and the other with DRM/KMS support from Linux mainline kernel.
Multi Framebuffer GUI interface Framework
LinRT Helium, Oxygen, Mercury and Cobalt Yocto BSPs with multi-framebuffers use Linux FSLC/NXP i.MX API Compatibility and provides most efficient IPU and VPU hardware support on Linux. This solution is recommended for applications that require the use of multiple separate-use displays, one as GUI touch panel and the other for the video screen, for example.
