The first Arm SystemReady IR certified platforms – NXP i.MX 8M Mini EVK & Compulab IOT-GATE-IMX8 gateway

NXP EVK Arm SystemReady IR

A few months ago, we noted SolidRun HoneyComb LX2K became a certified Arm SystemReady ES platform. SystemReady is a certification program by Arm that ensures systems just work with generic operating systems like in the x86 world. When we looked at the details of the program in the article, we noted there were different categories including SystemReady ES for embedded servers and SystemReady IR for IoT Edge applications. The first SystemReady IR platform – NXP i.MX 8 Mini evaluation kit Arm has just announced the first SystemReady IR platform had just been certified. That device is the NXP i.MX 8M Mini EVK, and that means that anyone that uses the i.MX 8M family of devices with the associated Board Support Package (BSP) can build platforms that will pass the same certification process and boot compliant Linux distributions with minimal integration effort. We can see more details about the certifications on Arm developer’s website. NXP i.MX 8M Mini EVK achieved certification with NXP 2021 Q2 pre-release firmware, version LF […]
