Dear List: I think this is my first post here.
This is a project that I have in my mind, but from what I see here I am wondering if it is doable: * General form factor: dev board with LCD, similar to a tablet * SoC: V3s * Display: 1024x600 parallel RGB LCD module with capacitive touch and adjustable backlight * Camera: OV5640 5MP camera module over MIPI CSI-2 * Storage: microSD card slot, onboard 64MB SPI Flash * Connectivity: RTL8723BS Wi-Fi and Bluetooth over SDIO and UART, Ethernet jack, USB 2.0, headphone jack * Other peripherals: USB to UART adapter for debug, embedded platform controller, battery charger Questions: * Can V3s juggle all those peripherals, especially the high resolution screen and the camera? * How to get mainline U-Boot and kernel into the SPI Flash, preferably without involving the SD card slot? * What is the best way and protocol for the embedded platform controller to talk with V3s? * How to implement the battery gauge, if the embedded controller is not providing the battery gauge feature? * Can I share one single interrupt line for all peripherals on board? Touch panel, RTL8723BS and the embedded controller all generates interrupts. * How to implement the power button and battery charging circuitry, allowing the V3s to be fully off while charging? I am not using AXP PMIC. * Is there any ETA for camera support? * Since I may use a STM32F4 (Cortex-M4F @168MHz) as the embedded controller, is there anything I can offload? * How to implement the clock tree, with the embedded controller in mind? Can I share crystals? (That is, using the clock out feature of the embedded controller to output the clocks for V3s.) -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
