Following Steps are For BEAGLE BONE BLACK in Debugging mode setup
In Windows Install oracle vm virtualbox extension pack from https://www.virtualbox.org/wiki/Downloads
sudo apt-get install arm-linux-gnueabihf*
download el_package.sh from https://sysplay.in/index.php?pagefile=downloads
chmod +x el_package.sh
./el_package.sh
download bbb_package.sh
chmod +x bbb_package.sh
./bbb_package.sh
1) Connect Beagle Bone Black pins on Jumper 1 ,
1 - Ground , 4 - TxD, 5 - RxD to CP210x USB to UART Bridge Virtual COM Port (VCP) hardware Gound TxD and RxD
2) Connect CP210x USB to UART Bridge Virtual COM Port (VCP) to PC where we should have already installed Linux Ubuntu 14.x.x what ever is latest version of OS from http://www.ubuntu.com/download/desktop/install-ubuntu-desktop
3) Documentation for installation of ubuntu is https://help.ubuntu.com/community/Installation
4) Login to Ubuntu Linux and press Ctrl+Alt+T to bring up the Terminal Window.
5) Connect Beagle Bone Black Mini USB to USB on the PC . This supplies power and also has connection and Inbuilt Ethernet over USB protocol as Network Demon running on Sitara 335x processor .
5) On the terminal setup communication between Beagle Bone Black and PC via the CP210x USB to UART Bridge Virtual COM Port.
6) Command : sudo minicom -s
7) Once the GUI is up select " Serial Port Setup " give parameters
8) Select exit from Minicom
9) type command "sudo minicom -o"
10) Once Prompt comes press "Enter" key
11) Give password as "Root" following should be your screen once you login to beagle bone black over USB-> UART
12) Command to connect Ethernet Demon over USB "ssh root@192.168.7.2"
13) Command to send files or copy files to Beagle Bone Black " scp uEnv.txt root@192.168.7.2: "
13) The Minimal SOC has UART protocol implemented on SOC hardware . So for minimal instructions that support would be UART .
14) Once Ethernet Deamon is up you can have the Ethernet over USB protocol . You will need minimal OS to run Ethernet over USB .
15) Now you should have 2 Terminal one with Serial over USB using Minicom application and 2nd one is Ethernet over USB as shown in below screen .
Following Steps are Specific to Bare Metal Programming on BEAGLE BONE BLACK
Use Linker_first.ldsand startup_first_small.s
and blink_LED.c
and rules.mk
using Makefile and build your .bin file
1) For Bare metal programming minimal required setup
2) Connect USB->UART and bring up the minicom window
3) Write Assembly code to set stack pointer and Ram Entry location
4) Write Linker file that specifies ram location
5) Write C source with minimal Peripheral clock initialization and blink LED
6) Remove the MLO file from the bootable Flash in the Beagle Bone Black
7) Without an MLO file the Beagle Bone Black would not boot up it will stop at prompt CCCCC
8) In the Minicom press A and than S to initialize the Xmodem file transfer protocol and select the required file that needs to be transfered .
9) lsblk command should show the master boot record
Beagle Bone Black with UART debug connected
USB to UART debug adapter
