pi5 study

Hi All,

I have done some work for the pi5 using the radioberry.

Happy reading.

Hi All,

After the study i did make a statemachine for the rp1 at the raspberry pi 5 

For sample rate of 192K  radioberry consumes only 4% ( 1 cpu) 

I changed the driver (also the rp1-pio driver)  no changes in the other radioberry components.  Really promising and i need to work it all out to share the result.

Enjoy.

And add my voice to the thanks for the hard work.  I'm looking forward to upgrading my Radioberry to a Pi 5.  It is appreciated.

Hi Johan,

Just received my 2nd radioberry for testing purposes, don't want to kill my transceiver all the time.

If you want me to test something let me know.

Also Techminds made a nice review of my software.

You can have a look here https://youtu.be/Y5Jd29SA8go?si=_YrHzZIrBvISDGI3

regards,

Paul

Very nice Johan.... after the two weeks bike trip  mind became fresh and you have reached almost  near to the result which we all need ... 

Eagerly waiting ... now happy with pi4 .. which is doing a wonderful job.. but we humans always  will look for the next ? 

congratulations for your genius works ...appreciate...no words ...

Yesterday I had  sent a mail and i do not know where it has gone.. any how 

Johan  ... you are doing a wonderful part of solving the rpi5 issue  with radioberry hat. 

After your bike ride you are almost reached at solution ...appreciate your efforts for the  hamdom  ..

eagerly waiting for the final release  and your go ahead notification. Till then happy with rpi4..

Using nibble (4 bits) for getting the rx stream; Utilization for 2 x 384 kc sampling rate.  As said in the design doc; aiming for 4 x 192K sampling rate is indeed very good possible.

Now looking to the TX part; this is data streaming the other way around.... see if that is working also hoping the rp1 driver is not having much additional needs

Hi all,

So the  next development iteration.

I have the RX and TX working using the PIO@RP1@PI-5   

The gateware is pushed to the HL gateware github page (for now only the CL025 FPGA)

The driver is pushed to the radioberry github page.

For testing i need to think how to get this going....

The radioberry consumes very little CPU in comparison with rpi-4 The CPU utilization is under 2% for 192 K sampling rate.

Iam quite busy with house renovation... so not much time.

Will let now how the testing could be done but as said i need to think about a good way of doing this.

Tnx! Johan, Great work.

I tried to build the PIO@RP1@PI-5 driver ‘radioberry.ko’.

but my skills are not very good, so I had to learn from my Copilot teacher...

Tonight, ‘radioberry.ko’ has not been built yet.

Running summary:

First, I created the /home/pi/git/rp1-driver/Module.symvers and rp1-pio.ko), which is written in SBC/rpi-5/device_driver/pio-mode/driver/Makefile.
The driver was obtained from the official Raspberry Pi Linux kernel repository. https://github.com/raspberrypi/linux
 

Actually, I git cloned it from Johan's github below. (raspberrypi/linux:rpi-6.12.y) due to a modification in rp1-pio.c
 -> Pull request #6918 rp1-pio config and transfer not right synced. In raspberrypi/linux;· pa3gsb opened on Jun 22
    cd ~/git

    git clone　https://github.com/pa3gsb/linux.git

Build radioberry driver.

$ cd  ~/tmp/rpi-5_driver_250723/device_driver/pio-mode/driver/src/

$ make clean

$ make

-  I had the following error and tried all Sunday, but still no radioberry.ko with the error

Attached gateware change pin (rx/tx) for RPi5_pr1-pio in pins.tcl file.

- control the radio via SPI

- RX stream via PIO sm and DMA uses 6 IO pins. - TX stream via PIO sm and DMA uses 3 IO pins.

Indeed it is not obvious to make it work.... that is why indicated to think about an easy test setup.

The pin usage can be found at the wili https://github.com/pa3gsb/Radioberry-2.x/wiki/GPIO-RPI---Radioberry

But by trying and experimenting you are getting a good understanding of all the small pieces, settings and configs which are needed to make it work.

Enjoy

Johan,

Trying to catch up on your Pi5 progress. 

Is there a current set of "how to" instructions to build a SD card to boot for a Pi5 version of a RadioBerry environment.

I would like to experiment with a Pi5 and Radioberry. I have a a couple of Juice boards, Preamps and Radioberrry boards in my inventory. 

But to start with, I would experiment with a Pi5 and Radioberry. Adding a Preamp as successful testing is accomplished. 

Again, Thanks for your contributions.
