Do first test on Rapsberry PI 5. #18

Closed enjoy-digital closed 1 week ago

enjoy-digital commented 1 month ago

While testing, describe all the steps in the current issues to be able to reproduce later and include in a README for future users.

CM4 IO

Status

Flash raspberrypi OS image

Switch CM4 to a mass storage

For CM4 board with an eMMC, a jumper must be present on J12 to disable boot on eMMC, an USB cable connected before power up

To switch the CM4 to a mass storage usbboot must be downloaded:

git clone https://github.com/raspberrypi/usbboot
cd usboot
make
sudo ./rpiboot

Flash

Updating the eMMC requires to use rpi-imager (see software page)

wget https://downloads.raspberrypi.org/imager/imager_latest_amd64.deb
sudo apt install ./imager_latest_amd64.deb
sudo rpi-imager

Note: during rpi-imager sequence it's possible to set login/password and to enable ssh.

Once eMMC is updated, remove jumper and power cycle the board. After 2 boot/reboot sequence the board is ready to be used/tweaked.

Note: usb cable must be removed to be able to use keyboard/mouse connected to USB HUB connectors

Configuration update/fix

/boot/firmware/config.txt must be updated with following lines:

# required for dma mask
dtoverlay=pcie-32bit-dma

Tested at 10MS/s: no problem sound looks good and no overflow/underflow

GNURadio with FM receiver flowchart

Works but lot of Os, maybe the flowchart must be optimized to reduce CPU load.

Raspberry PI5

Status

Flash raspberrypi OS image

Unlike CM4, RPI5 uses a classic SDCard as rootfs

Flash

Updating the eMMC requires to use rpi-imager (see software page)

wget https://downloads.raspberrypi.org/imager/imager_latest_amd64.deb sudo apt install ./imager_latest_amd64.deb sudo rpi-imager

Select:

Note: during rpi-imager sequence it's possible to set login/password and to enable ssh.

After 2 boot/reboot sequence the board is ready to be used/tweaked.

Configuration update/fix

/boot/firmware/config.txt must be updated with following lines:

# required for dma mask and MSI instead of MSI-X
kernel=kernel8.img
dtparam=pciex1=on
dtoverlay=pcie-32bit-dma-pi5
dtoverlay=pciex1-compat-pi5,l1ss=off,no-l0s=on,no-mip=off

/boot/firmware/cmdline.txt must be updated to add following options:
