Hi, I'm working on a couple of projects requiring the classic Micro controller features (low power, deterministic real time processing) and the classic UX, flexibility and functionality of Linux /android.
Most SoCs today provide many high level external hardware interfaces (like Camera, USB, HDMI, etc) but some projects require additional drivers and interfaces to handle different external hardware. Usually we solve the interconnectivity with extra MCUs, FPGAs or other specialized chip interfaces available. Sometimes, we design product boards with two solutions: a Cortex A SoC like Allwinner/rockchip/Omap series and a small MCU Cortex M like the STM32 series, but with a powerful A80, it could change forever. I will receive my first Optimus board soon, and I want to customize the kernel to create a classic Linux running on the powerful 4x A15+ GPU and Nucleus (or Free RTOS) on one or two of the A7 of the Allwinner A80 Soc. (I made similar kernel works with MTK SoCs in the past, but never try to run two operating systems in the same chip at the same time) Both projects require continuous operation and deterministic real time response on the low power processor(s) (RTOS on A7). User interaction (Linux on the A15 + GPU side ) is only eventual, so termal issues by running almost all processors at the same time occasionally, should not be a problem. If anyone anticipate a significant barrier to build a kernel of this type, please share it here, I will really appreciate. I will share the results and evaluation test here Additionally I will really appreciate if someone could help me to get the A80 user manual, (please contact me by email). Both projects require access to low level A80 features for special hardware interfaces and the user manual is a must for both projects and future product projects related with the A80. I want to switch almost all my projects to Allwinner A80. Javqui -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
