Have you considered the PocketBeagle. Its power would be a soldered battery
connection. It is much smaller than a BBB. And per the issues raised by Dennis
reply, I believe all chips are soldered in. There is a working port of freeRTOS
with TI starterware on GITHUB which boots fairly fast.
This is the resistance at two temperature points. The first point (25%) is
where the “normal” resistance is taken. The table below the values is what the
resistance is a the second point.

Are you expecting to also charge the battery using the Beaglebone Blue? If
not, why not connect the battery to the DC jack input?

Dave,
I presume by PB you mean Pocketbeagle.
Assuming the above and looking at the .dts file, I do not think this will work.
I could easily be wrong, but the way I read the .dts file, you are trying to
use the LCD output pins from the am335x (mode 0). On the Pocketbeagle those
pins do
Am I correct in assuming that we are talking about documentation? Also the
older forums. I presume that all software (compilers, SDKs, etc) will still be
available.
I also started making a list. I will be interested to see your list(s)!

Configuration:
PocketBeagle (PB) with an I2C connection to a MPU6050 breakout board. Power
to the MPU6050 board is 3.3 volts from the PB.
The PB is connected to a CurieNano using uart TX and RX. This is serial
port 4. The two boards have their own power supplies. There is a common
ground

should either design a circuit to prevent this, or design your system to ensure
that if one board has power, both do.

Jim,
Thanks for the explanation. I think the solution for me is to power both boards
from the same power source so that they are always both on or both off.
One minor problem I have is that when I am downloading a script to the
CurieNano, it is powered from the USB connection that is
+ of the microcontroller.
The diode was not specifically meant to handle the current load of driving the
entire chip (and any off chip devices that may also b attached to the V+ bus
the controller is on).

Thanks so much Graham, I am ordering that exact board, do you plug the CTS, VCC
and DRS into anything or you DON’T use those at all?
Thanks so much for your help, I was pulling my hair out trying to find the
right board.

for the reply. However the problem I have is that I removed all
the external pins including pins for power. Is there a way to set up a serial
connection via the USB 2.0 interface?
[Graham Stott] Yes, except that it would require a software driver which makes
the USB a virtual UART. So that does
I strongly agree with Jim that the way for you to make progress is to connect
up a serial cable. A FTDI FT232 USB to UART Converter is one easy way to do
this. Only three wires (TX, RX and GND) from the pocket Beagle.
Once you have the serial output working, you could also try to boot
If (as Dennis asked) you are asking about this program for a bare-board (no OS)
configuration, then I suggest you look at TI's starterware. It has routines for
I2C and GPIOs that you can use from the C program to provide the functionality
you are asking for. You can use CCS for the development.
First of all I have not used this particular adapter. All the similar adapters
I have used get their power from the USB connection and have a jumper to select
between 5v and 3.3 volts for the RX and TX interface. Looking at the picture
of the board, I cannot see a jumper. As the Pocket Beagle
The code you copied below seems to be incomplete. After the routine
“set_slave_addr” and before the comment “//P9 Connector settings”, I believe
there is missing code. I therefore cannot tell if your setup code is complete.

I did a quick review of the set up part of the code you posted. The code is
not complete. It is missing some clocks setup.
You should download the TI AM335x Technical Reference manual. I have version
spruh73q. Look at the picture on page 1563. You will see that the L4_per is
connected to
So It looks like the I2C test that you are running has an issue. Can you try
something simple. For example, the hello world test.
And no you do not need a JTAG to debug. You should be able to use printf.
