U-Boot and Kernel from source

Toradex: Build U-Boot and Linux Kernel from Source Code

Note: Upstream kernel 5.8.0 seems to work for me.

Now we need to figure out how this thing boots.

It looks like we need to build a Boot Container

Raspi 4 - 8 Gig RAM

I took the headless Raspberry Pi OS (Debian) https://www.raspberrypi.org/downloads/.


ssh is disabled by default ;)

sudo mount /dev/sdb1 /mnt/mala1/
cd /mnt/mala1

sudo touch ssh

cd /
sudo umount /mnt/mala1

Now you can watch your dhcp server and check the Ip address the raspi takes.

ssh pi@<ip-address>
pw: raspberry


sudo raspi-config

with this we can resize the rootfs

enable serial console

I ALWAYS want a serial console, but this is not enabled by default.

sudo nano /boot/config.txt

add to the end


Now if you reboot you should get some output on serial console.



rootfs from nfs

The kernel commandline comes magically from here: http://git.yoctoproject.org/cgit/cgit.cgi/meta-raspberrypi/tree/recipes-kernel/linux/linux-raspberrypi.inc#n30

So if we want to boot over nfs instead of the SD card something like that works:

#CMDLINE ?= "dwc_otg.lpm_enable=0 ${SERIAL} root=/dev/mmcblk0p2 rootfstype=ext4 rootwait"
CMDLINE ?= "dwc_otg.lpm_enable=0 ${SERIAL} root=/dev/nfs rootfstype=nfs nfsroot=,v3,tcp ip=dhcp rootwait"

Power supply issue:

1-Using the MAIN RJ45 POE You can use Passive or active 48V POE Note if Gigabit Ethernet is required you will need ACTIVE POE 802.3af Gigabit capable POE Other wise You will default to 10/100 Ethernet. Passive POE uses spare pins for Power 4,5 7,8, Gigabit Ethernet uses all available Pins for data, so Passive POE adapters will not work for Gigabit mode, only 10/100 Mode will be OK.

2-Using DC Power Jack any supply with 48V DC should work OK 24W or higher is sufficient in most cases.

Voltage range is 39VDC to 56VDC for operation of RS-PRO RS-Pro is capable of supporting 30W POE devices

The Ubiquity specs now say the RS Pro needs 40-56 volts, so there you go.

You can plug a 48 volt power supply directly into the RS Pro's power jack. The pin size is 2.1mm, the barrel is 5.5mm, positive pin, outside is ground (inside diameter 2.1mm, outside 5.5mm)
