SemiDrive D9-Pro (D9360) Arm Cortex-A55/R5 processor powers industrial CPU module for motor control

MYiR MYC-JD9360 is a CPU Module powered by SemiDrive D9-Pro (D9360) processor with six Arm Cortex-A55 application cores, a dual-core lock-step Cortex-R5 real-time core along with a PowerVR GPU, 4Kp30 H.265/H.264 VPU and a 0.8 TOPS NPU, and designed for motion control and industrial applications.

The MYC-JD9360 CPU module also comes with 2GB LPDDR4, 16GB eMMC flash, 16MB QSPI Flash, 256Kbit EEPROM, and exposes I/Os such as PCIe 3.0, USB 3.0, CAN FD, and TSN-enabled Gigabit Ethernet through a 314-pin MXM connector. The company also provides the MYD-JD9360 development board to quickly get started with the module and evaluate the solution.

MYiR provides Yocto Linux and Ubuntu support for the module, and Android is coming soon. The D9-Pro is supposed to be a relatively new processor that was sampled in October 2022, but SemiDrive must have kept the legacy SDK used in their previous generation D-series processors, as the MYiR Tech website lists Linux 4.14, Ubuntu 18.04, and Android 10 in the software section.

  1. > the MYiR Tech website lists Linux 4.14, Ubuntu 18.04, and Android 10 in the software section.

    The SoM’s spec sheet PDF lists ‘uboot_2021.04’ and also ‘official kernel_4.14.61 version customization’ (4.14.323 is current 4.14 LTS version but since they’re reusing their SDK the version string doesn’t matter since this is a crappy BSP for sure). The Ubuntu version that went EOL few months ago is also confirmed and wrt Android it reads ‘Android 10 (not available at present)’.

  2. This could have been a dream chip for several applications, and yet with such outdated BSP…
