[linux-sunxi] Shared interrupts

Quick question: can I share an interrupt pin across several peripherals in just device tree? Background: I am trying to design a V3s board (for giggles,) but I have exactly one interrupt-able pin left. I have several peripherals that may generate interrupt, thankfully all as open drain

[linux-sunxi] U-Boot: Can I use I/O expander in U-Boot

Dear List: I am designing a board based on V3s, and I am running out of GPIO pins, let alone pins with interrupt capability. Can I add an I2C GPIO expander like MCP23008 to provide both additional GPIO pins and interrupt lines, and still make everything work under both booted Linux and U-Boot?

[linux-sunxi] What is the status of mainline u-boot support for SPI?

Dear List: Hello. I am in the middle of cooking up a V3s experiment board. For that board I want to allow the board to boot even without a microSD card installed. SD0 is the microSD slot, SD1 is being used to interface a SDIO Wi-Fi module, and only the SD2/SPI0 port is open. I know that I

[linux-sunxi] Help needed: FEL and UMS support in A64 U-boot

Dear List: I have added a 16GB eMMC chip to my OrangePi Win Plus, with the intention of not having it hogging one of my microSD cards. (I may be one of the weird people that likes to hack hardware as well as software.) Now I need some help to put the actual system image into the eMMC. I have

[linux-sunxi] Noob question: is this doable?

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

[linux-sunxi] SPI NOR boot planning

I am trying to create an open source point-and-shoot camera based on some spare parts lying in my bin and the V3s, but still in the style of a single-board computer. V3s don't have a lot of I/O pins and the planned features exhausted it. (I even

[linux-sunxi] V3s NOR size limit

Dear List: I wonder if V3s BROM, U-Boot and Linux kernel can support more than 24 bits in SPI NOR addresses? I am thinking about creating a gadget that boots off NOR directly for a full embedded Linux build. Max -- You received this message because you are subscribed to the Google Groups
