xefil Posted February 9, 2018 Posted February 9, 2018 Hello to all! I'm using Armbian on my BananaPi board. I've the following version: ARMBIAN 5.38 stable Debian GNU/Linux 9 (stretch) 4.14.15-sunxi BOARD=bananapi BOARD_NAME="Banana Pi" VERSION=5.35 LINUXFAMILY=sunxi BRANCH=next ARCH=arm IMAGE_TYPE=user-built BOARD_TYPE=conf INITRD_ARCH=arm KERNEL_IMAGE_TYPE=zImage I need to follow these instructions to wire a radio on the board: https://www.mysensors.org/build/orange But I cannot find the script.bin file. Why? I can remember the file was here on old releases. Any help or suggestion? Thanks, Simon

I've started reading it and it's a little complicated. The part that I think it's referred on what I need is: Quote ### spi0 Activates SPI controller 0 to use it with other overlays and sets up the pin multiplexing for it SPI 0 pins (MOSI, MISO, SCK, CS0, CS1): PI12, PI13, PI11, PI10, PI14 ### spi1 Activates SPI controller 1 to use it with other overlays and sets up the pin multiplexing for it SPI 1 pins (MOSI, MISO, SCK, CS0): PI18, PI19, PI17, PI16 ### spi2 Activates SPI controller 2 to use it with other overlays and sets up the pin multiplexing for it SPI 2 pins a (MOSI, MISO, SCK, CS0): PC21, PC22, PC20, PC19 SPI 2 pins b (MOSI, MISO, SCK, CS0): PB16, PB17, PB15, PB14 Parameters: param_spi2_bus_pins (char) SPI bus 2 pinmux variant Optional Default: a Supported values: a, b Determines what pins SPI bus 2 is exposed on if SPI 2 is used ### spi-add-cs1 Activates SPI chip select 1 on SPI controller 0 This overlay is required for using chip select 1 with other SPI overlays SPI 0 CS1 pin: PI14 ### spi-jedec-nor Activates MTD support for JEDEC compatible SPI NOR flash chips on SPI bus supported by the kernel SPI NOR driver SPI 0 pins (MOSI, MISO, SCK, CS0, CS1): PI12, PI13, PI11, PI10, PI14 SPI 1 pins (MOSI, MISO, SCK, CS0): PI18, PI19, PI17, PI16 SPI 2 pins a (MOSI, MISO, SCK, CS0): PC21, PC22, PC20, PC19 SPI 2 pins b (MOSI, MISO, SCK, CS0): PB16, PB17, PB15, PB14 Parameters: param_spinor_spi_bus (int) SPI bus to activate SPI NOR flash support on Required Supported values: 0, 1, 2 param_spinor_spi_cs (int) SPI chip select number for SPI NOR connected to SPI bus 0 Optional Default: 0 Supported values: 0, 1 Using chip select 1 on SPI 0 requires using "spi-add-cs1" overlay param_spinor_max_freq (int) Maximum SPI frequency Optional Default: 1000000 Range: 3000 - 100000000 ### spi-spidev Activates SPIdev device node (/dev/spidevX.Y) for userspace SPI access, where X is the bus number and Y is the CS number SPI 0 pins (MOSI, MISO, SCK, CS0, CS1): PI12, PI13, PI11, PI10, PI14 SPI 1 pins (MOSI, MISO, SCK, CS0): PI18, PI19, PI17, PI16 SPI 2 pins a (MOSI, MISO, SCK, CS0): PC21, PC22, PC20, PC19 SPI 2 pins b (MOSI, MISO, SCK, CS0): PB16, PB17, PB15, PB14 Parameters: param_spidev_spi_bus (int) SPI bus to activate mcp2515 support on Required Supported values: 0, 1, 2 param_spidev_spi_cs (int) SPI chip select number for SPIdev on SPI bus 0 Optional Default: 0 Supported values: 0, 1 Using chip select 1 on SPI 0 requires using "spi-add-cs1" overlay param_spidev_max_freq (int) Maximum SPIdev frequency Optional Default: 1000000 Range: 3000 - 100000000 Due I'll need to connect on this board two radio (one NRF24L01+ and one RFM69), I fear to make some damages, so I ask here. I would start with one radio first, the RFM69. But here comes the first question it's not totally clear for me: 1. Is the BananaPi able to have two radio connected on the GPIO? Seems yes if the above doc speeks about SPI 0 - 1 - 2 all with required MOSI, MISO, SCK, CS.... But I've read somewhere for RPi the following: Quote Adding /dev/spidev1.0 is required since /dev/spidev0.0 is used for the onboard NAND flash 2. I'ts valid for BananaPi as well? BTW then, let's start with the first radio assuming I can start with bus0. The overlay should look like: overlays=spi-spidev param_spidev_spi_bus=0 That should create a "/dev/spidev***" device. This should give me those connections GPIO available: MOSI: PI12 -> CON3-PORT19 MISO: PI13 -> CON3-PORT21 SCK: PI11 -> CON3-PORT23 CS: PI10 -> CON3-PORT24 Then I'm missing the power 3.3v (CON3-PORT01), ground (CON3-PORT06) and IRQ, which should be ok any normal PIN (i.e. CON3-PORT22). Until here makes it sense?? Sorry, but as written above I fear I could make some mistrakes and damage the devices. Assuming the above works, how can then I add a second spidev? This is something I cannot understand from the documentation. Many thanks, Simon
vlad59 Posted February 14, 2018 Posted February 14, 2018 The banana pi only has 1 SPI Unless I'm mistaken. I used SPI some time ago and IIRC simply adding spi-spidev to the overlay did the trick. The Banana pi has no Nand. Hope this helps
