Until now I used Microchip PIC, to program this microprocessor there is MPLAB. I would like to make a step forward and learn about other microcontrollers.
I found the BeagleBone Black quiet promising for my DIY project because there is a 2GB flash and 1GHz clock. I have a few question as a beginner: On the eewiki I found a tutorial where they are describing how to start, but this tutorial is based on SD card. If I want to use only the 2GB flash card than how can I load my software on it without using SD card?
I saw on that page that there is a bootloader(UBoot), what is this for? For example I just wan to blink a led, using PIC it is a few line of code which I upload and that's all, If I would like to do the same with a BeagleBone Black what I suppose to do? Do I need UBoot? How can I write this piece of code to the eMMC of the BeagleBone?
If I have a board without any preloaded software(including bootloader) how can I start to upload a software?
