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
- S2 Boot switch button
- S3 Power 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!
