MYiR provides a Linux BSP with all drivers, plus two Yocto images (with or without GUI), and OpenWrt. Note that one key point is that the Renesas RZ/G2UL processor lacks the 3D GPU found in the similar Renesas RZ/G2L and RZ/G2LC microprocessors, and it’s suitable for entry-level industrial HMIs with 2D graphical interfaces, medical devices, PLC controller, charging pile, energy storage system, and others. As usual with MYiR Tech, the source code and documentation are not available publicly but will be provided to customers…

    1. The hardware manual for the Renesas RZ/G2UL processor reads “Support WXGA (1280 × 800), 60 fps”

  1. I wonder what the use case for that M33 might be. It may make sense in mobile, battery-powered applications (**if** one can wake up just the M33 and not the rest), but that doesn’t quite seem to be the target of that chip, or is it?

    1. They specifically mention industrial applications, where there has been a long-growing trend of including small MCU cores on application processors like this to handle use cases with real-time requirements. This saves the added cost + complexity of connecting a separate microcontroller to the application processor to handle those kinds of tasks.
