No I don't release my code to the public. Starterware has SD examples but they
don't work well. You could make improvements to it to make it work better.

Bare-metal is always going to out-perform linux and even an RTOS if done right.
For beaglebone aka AM335x, start with Starterware. Over the past 3.5 years of
working with beaglebone, I've developed a bare

understanding what registers the gel file is programming by reading the TRM
extensively.Make sure caches are enabled and code is optimized for
speed.Without this the rest of the steps are pointless

One thing to be aware of is the CortexA8 doesn’t perform very well if you don’t
have Data and Instructions Cache enabled and you also have to have the MMU
configured and enabled. For example, toggling a GPIO in Starterware with no
Cache or MMU enabled, I get about 120KHz but if I enable both Cac

There is a reason for this. The beaglebone is not meant to be used as a
bare metal system. The process

Hello,
thanks to the people who want to be helpful, but I really have to tell you
that it is not easy to start (bare-metal programming)
with BBB.
Here are some of the troubles I ran into:

Starterware includes a bootloader that pulls a program from the SD card and
loads it and runs it. As far as toggling the GPIO pins very fast, you're not
going to get good results. This is an applications processor, not made for real
time programming. That's why TI included 2 PRU units on the chi
