Hi DD, I plan to start a blog of my own as soon as I can get away from making money.
I will chronicle my struggle with the ARM and will surely fleece/rip apart C, Linux and all that stuff. Also might be able to show some of my assembly work. Do get the J-tag. it seems easy to use and makes downloading code ( or is it uploading?)a breeze. Get your J-tag from Aliexpress. Yes they are all the same. (Segger Clones) Also get the Saleae logic 8 and 16 wire logic analyzers(clone/rip-off) . The 16 bit analyzer at 27US$ post paid is a steal. (@Aliexpress) The 16 line because you can set it to monitor only 3 lines so that it may then run at 100MHz. The 8 line device can theoretically do a max of 25 MHz. This thing is an extremely useful device. And I do emphasize extremely. About 50 times better than a debug tool or software.

Thanks for the link I have a J-tag which cost me US$10.73 post paid from this guy here. www.aliexpress.com/item/ARM-Emulator-supports-ARM7-ARM9-ARM11-Cortex-M3-core-ADS-IAR-STM32-ARM-Emulator-JTAG-interface/1457219031.html There are a host of others selling the J-Tag on Aliexpress. I would not recommend this seller as they forgot to ship the CD and have never kept their promise to send a replacement. Anyway I downloaded the drivers from J-tag directly. (student version, which is complete) The device seems to be working well.

Here is a tutorial on the BBB with starterware & a jtag cable. http://anthonymerlino.us/uncategorized/getting-started-with-beaglebone-black-bbb-and-starterware It looks thorough. Need to buy jtag first. It should not be difficult getting around the starterware code. And one can rip their drivers! Also, on this forum under thread Confused about developing bare-metal applications for BBB Frank Hunleth gives instructions at 7/22/13 and 7/23/13 on how to hack u-boot. So, it looks like we have our work cut out for us! later..............dd On Monday, October 28, 2013 5:18:24 PM UTC+2, azzythehillbilly mir wrote: Hi Forum, I have a problem and I am hoping that I kind soul will direct me whereby I am able to help myself get on my feet. This is a bit embarrassing, but here it goes. I got myself a BBB because I want to switch from using MCS-51 processors and the like. I have no formal schooling in processors or electronics. I started working on processors around 1980 when I got hold of an Ohio scientific and later an AppleII+. Later moved to Z80/Z8000/8086/68030 and similar as I started to formally design HW and SW for embedded systems. Never had to bother even with C so have been hacking merrily away with Assembly only. Rarely adding ( with difficulty) bits of code for floating point when my own extended math routines simply would not do. This works for me as I have learned to cram as much functionality as possible into limited resources. I can get working code written and debugged faster than most C coders can. I know nearly zero about Linux//Ubuntu/Fedora. Unless someone has worked on the simple old controllers one might not understand how exciting ( mouth watering even! ) it is to contemplate the peripherals this Sitara 3359 processor provides. I just need to get a jump start. Here is the problem, I want to write code for the Sitara-3359 and learn the nuts and bolts of low level programming (assy). I need some kind of a simple IDE Where I can take control of the processor from reset onwards ( barring un-by passable initializing code prewritten into the processor?). I have been searching all over the net for just that but come up frustrated by the huge number of names/acronyms and all. There are just too many branches to investigate. I get lost every time I try. For the moment I want merely to exercise the Sitara and study its responses, no desire to write any commercial application (with the possible exception of a camera interface for my telescopes). Please kindly somebody point me in the right directions. Once I have the correct IDE set up I can take over and dive into the details. No problem there.
