What are you actually trying to do? That's a 50Mbit sustained transfer
rate if bit time is 20ns. 100Mbit if 10ns. And 4 channels. That's
200-400Mbps. You're moving a *TON* of data even at slower clock
rates--there is no resource on the BBB that can keep that up very long.
This seems quite q
Thank you TJF for that detailed answer and thank you too Andrew for your
insights.
We are trying to extract radar data from one radar board. The goal is not
have it working at 50MHz (which is the system max rate), but have the
possibility if needed. Probably we will work at 10 to 20MHz, and the
I'm using the PocketBeagle in one of my projects and have noticed 5 times
out of maybe 100 that the CPU runs very hot, enough to burn my fingers.
Running the TOP command, I see nothing using more that 1% CPU usage. When I
cycle the power, the temperature returns to normal. I'm concerned that it

state between the CPU and modem that makes the CPU run hot and this is

Hi! Propably the trouble is in the wrong power circuit to USB modem. Use
the USB power switch to power USB device connected to PocketBeagle board.

I too was skeptical of FPGAs until recently, I think you owe it to yourself to
check out Zynq and Altera which combine FPGAs with ARM cores. The PL (FPGA
part of these chips) can align the clock edges and write the data into the
memory of the ARM processor. You might find it is possible to do
Thank you for your point of view Steve, the thing is I preffer to have
community behind like in the beaglebone and a smaller form factor, besides
my goal is to generate radar board that people could use in their
projects. If PRU is enough, would be fantastic, a little of AI from the
beaglebone
Hi all,
Like the title says, I have a BeagleBone AI running the latest (as of
writing) Debian Buster 10.3 image (https://beagleboard.org/latest-images).
It seems there is a memory handling issue when I try to run the openCL
examples found under `/usr/share/ti/examples/opencl`. See the attached
You can certainly persist, but I'm going to point out the existence of
chips like the AWR1843--"Single-chip 76-GHz to 81-GHz automotive radar
sensor integrating DSP, MCU and radar accelerator":

This is about $30, and does all the RF-y things while sending your
Agreed. 3G modems can pull a remarkable amount of power (up to 2A!) under
certain circumstances.
That's going to tax the power systems of the PocketBeagle pretty heavily.
You need to have something which you can use to turn on/off the power to
the modem which bypasses the PocketBeagle power s
Thank you for your comments. It seems I must revise the design for the
power. It's a bit out of my area of knowledge so will need to do some
research.
The Beaglebone Black has always worked perfectly for my application but the
PocketBeagle does not have the same USB socket available so I wired
You do want to look at the PocketBeagle FAQI which shows the proper way to wire
up a USB --

I find the names to be somewhat confusing, and you do want to be careful if
you are wiring up an additional
