On-board hardware

  • AM3358BZCZ100 CPU
  • 512MB DDR3 memory
  • 4GB eMMC (MMC1, 8bit)
  • uSD slot (MMC0, 4 bit)
  • 100Mbit/s ethernet (MII1)
  • USB host (USB1)
  • USB slave (USB serial, USB network) (USB0)
  • 24LC32A 32Kb I2C EEPROM (8kibytes) (I2C0)
  • S1 Reset button

Serial console

AM3359 UART0 is connected to header J1. Use "USB to TTL serial cable 3.3V". Pinout:

Header J1 (J1 = black wire):

1 - GND - (Black)
2 - nc - (Brown)
3 - nc - (Red)
4 - UART0 - RX (Orange)
5 - UART0 - TX (Yellow)
6 - nc - (Green)
The default serial port settings for the board are:

Baud: 115,200
Bits: 8
Parity: N
Stop Bits: 1
Flow control: None

Use this one: http://www.digikey.ca/product-detail/en/ftdi-future-technology-devices-international-ltd/TTL-232R-3V3/768-1015-ND/1836393

Figure 4.1 TTL-232R-5V and TTL-232R-3V3, 6 Way Header Pin Out https://www.digikey.ca/en/datasheets/ftdifuturetechnologydevicesinternationalltd/ftdi-future-technology-devices-international-ltddsttl232rcables

The 5-pin plug mates with the 5 pin header on the BBB. The "black" wire is the ground, connects to header pin 1.

To force a boot from the microSD card, press S2 (Boot Switch) and S3 (power button) at the same time.

BeagleBone Black Board Setup Steps

The first five steps without the "cape". A "cape" in the BeagleBone is similar to the "shield" in the Raspberry Pi. For more information about the BeagleBone capes see https://beagleboard.org/capes

1) Change password/host-name

After flashing the image from the microSD Card and rebooting the BBB, change the password and hostname.

5) Edit spi_test.c

debian@alphabbb00:~$ cd iobb
debian@alphabbb00:~/iobb$ ls blog-apps
hello.c  Makefile   speedtest.c   spi_test.c
debian@alphabbb00:~/iobb$ emacs spi_test.c

In line 51, change from pin_direction=SPI_OUTIN to pin_direction=SPI_INOUT

  if (POCKETBEAGLE)
    pin_direction=SPI_INOUT;
  else // Beaglebone has MISO and MOSI choice unallocated. This matches the demo code:
    pin_direction=SPI_INOUT;

In line 61, edit SPI_RX to SPI_RXTX

    spi_ctrl(SPI_BUS, SPI_CH0, SPI_MASTER, SPI_RXTX, /* use SPI_TX or  depending on needs */
             SPI_DIV32, SPI_CLOCKMODE3, /* 48 MHz divided by 32, SPI mode 3 */
             		SPI_CE_ACT_LOW, pin_direction, 16); //16-bit transactions 

In line 73, change the transmitted data from 0 to any hexadecimal number. In this example, we change it to "0x1234"

  for (i=1; i<20; i++) 
  {
    spi_transact(SPI_BUS, SPI_CH0, 0x1234 /*or integer to transmit data*/, &rxval);
    printf("Received: 0x%04x \n", rxval&0xffff);
    iolib_delay_ms(500);
  }

At this point the four spi devices: spidev1.0, spidev1.1. spidev2.0 and spidev2.1 should exit in the BBB.

debian@alphabbb00:~$ ls /dev/spi*
Spidev 1.0  spidev1.1   spidev2.0   spidev2.1 


6) Attach the BBB to the cape. The spi devices don't exist when the cape is connected to the BBB, to make the spi devices available follow step 7.

7) Edit uEnv.txt

debian@alphabbb00:~$ cd /boot
debian@alphabbb00:/boot$ sudo emacs uEnv.txt

In line 18 through 22, uncomment and add "BB-SPIDEV0-00A0.dtbo" to make spidev1.0 and spidev1.1 available. Also, uncomment and add BB-SPIDEV1-00A0.dtbo for spidev2.0 and spidev2.1. Since we only need spidev1.0, we will only add "BB-SPIDEV0-00A0.dtbo"

###Additional custom capes
uboot_overlay_addr4=/lib/firmware/BB-SPIDEV0-00A0.dtbo
#uboot_overlay_addr5=/lib/firmware/BB-SPIDEV1-00A0.dtbo
#uboot_overlay_addr6=/lib/firmware/<file6>.dtbo
#uboot_overlay_addr7=/lib/firmware/<file7>.dtbo

8) Reboot the BBB than check if the spi devices are available

debian@alphabbb00:/$ reboot
debian@alphabbb00:/$ ls /dev/spi*
spidev1.0  spidev1.1  

9) Run the spi test

Since the spi devices are now found when the cape is connected to the BBB, we can comment out line 37 in spi_test.c

debian@alphabbb00:~/iobb/blog-apps$ emacs spi_test.c
#configure_spi_pins(17, 18, 21, 22); // CS, D1, D0, CLK

We also edit the Makefile to include the path to the library and the header file

debian@alphabbb00:~/iobb/blog-apps$ emacs Makefile
debian@alphabbb00:~/iobb/blog-apps$ make
gcc -I../ -o hello hello.c -L../ -liobb
gcc -I../ -o speedtest speedtest.c -L../ -liobb
gcc -I../ -o spi_test spi_test.c -L../ -liobb

Now we are ready to the run the spi test!
