Hi,
The romcode for BeagleBone Black USB0 for usb booting, how to setup tftp server on the PC end? such as IP address for tftp server? Can I use 192.168.7.1 for tftp server?
If there is a good reference resource link, please advise.
Thank You,
David
Hi @dzhou, the author of https://github.com/ravikp7/node-beagle-boot wrote his own implementation of tftp.
He used 192.168.6.1 for the server…
For a pure tftp server, i’ve had good luck with tftpd-hpa:
https://packages.debian.org/buster/tftpd-hpa

Hi Robert,
When I power BBB with S2 pressed, the USB0 is initiated with NDIS adaptor interface on PC. The NDIS adaptor is automatically assigned with 192.168.3.1. I am trying to set tftp server on the PC using 3.1. But nothing initiates a download from PC to BBB.
If I use 192.168.6.1, after rebooting, it says invalid interface for the NDIS adaptor
Thank you,
David
What OS are you using on your development server?
Regards,
I am using Linux Ubuntu PC and Windows 7 PC as tftp server to download files. The U-boot is compiled with a VirtualBox Debian. But at this point, I want to make sure that downloading u-boot-spl.bin file is initiated through USB0 booting mode.

Hi @dzhou, I’m sorry, but using USB with virtualization is going to be nothing but trouble.
I just verified, that Ubuntu 18.04.x works with ravikp7’s directions: (Ubuntu 16.04 is too old, and I have not tried Ubuntu 20.04, but it might be way too new…)

So the eMMC on this BBB is now currently mounted on my Ubuntu 18.04.x test machine as /dev/sdb… I can then use https://www.balena.io/etcher/ to install any BeagleBone image on to the drive…

Hi Robert,
My Ubuntu 16.04 is also used to bitbake Yocto for other products with iMX SOM. I have very reluctant to update into a newer version, because it is very possibly I cannot bitbake yocto.
I will digest the useful information you posted tomorrow.
Thank you for your help.
David
Hi @dzhou, it helps to have a large collection of SATA/SSD drives, and just a swap caddie in your development machine.
I just got Ubuntu 16.04 working, the only thing you need to do is install a 3rd party version of nodejs and remove ubuntu’s default version as it’s too old.
sudo apt-get update
sudo apt-get install build-essential libudev-dev libpcap0.8-dev curl git
sudo apt-get purge nodejs npm
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install nodejs
voodoo@zeus:~$ nodejs --version
v8.17.0
git clone https://github.com/ravikp7/node-beagle-boot.git
cd ./node-beagle-boot/
npm install
sudo npm start
Hi Robert,
I tried the nodejs in my virtualbox with Debian. It seems working but not finished.:
beagle-boot@1.2.1 start /home/dzhou/BeagleBoneBW/BareMetal/node-beagle-boot
node runServer.js

======================
I was wandering where is the folder location that the nodejs downloads u-boot-spl.bin from?
And how to specify the file names to be downloaded?
Thank you,
David
Well, the u-boot-spl.bin and u-boot.img files are under the bin folder of the nodejs installation. It seems to me the u-boot-spl.bin is looking for micro SD for booting uEnv,txt file. It stops there, I guess.
Thank you,
David
Hi @dzhou, retry with-out VirtualBox or any Virtualization software. Anytime low level USB is involved with Virtualization, tons of problems exist, thus no open source developer today will ever touch it to debug.
Regards,
Hi Robert,
I tried on the Linux Ubuntu (16.04). I installed nodejs. Everything seems ok. The nodejs window shows the last line of message as "SPL TFTP transfer completed, …80}
There is a popup Window on Linux which show rootfs. But the UART serial monitor windows (through console debug port of BBBw), it keeps displaying ‘/’ ‘|’ ‘’, ‘|’ … (One character per line with carriage return). It doesn’t stop and cannot be stopped. I have waited for very long time.
Best Regards,
David
That’s expected, u-boot is running a “USB” Flash Drive application, the Window “pop-up” is your eMMC on the BBBw. So use balenaEtcher - Flash OS images to SD cards & USB drives or dd to write your *.img file to the new drive.
Then use “ctrl-c” to kill it from the serial console.
Regards,
Sorry, could you please explain a bit more on the “dd to write your *.img file to the new driver”.
I had created a usb stick written or created by “Balena Eecher”. It was plugged into the USB host port (USB1) on the BBBw. But it seems to me nothing is happening. What is the file format and an example image file name for *.img? A SD card flasher will work as USB flasher?
Q: The image to be written to a USB stick ( using dd or Etcher), what is the format of the image? I mean as eflasher or normal sd card bootable image? I assume a sd card flasher image. I am wandering it can be used for USB stick. I don;t find any USB flasher pre-build image for BBBw.
Thank you,
David
No, you don’t need a secondary USB Flash drive plugged in the BBBw.
The “node-beagle-boot” project, boot’s up a “blank” BBBw eMMC, into a “USB Flash Drive”… That “drive” window that popped up in Ubuntu is the eMMC on the BBBw. So use “Balena Etcher” to write you custom RootFs to the eMMC.
Remember you have a custom OSD335x board with a blank i2c eeprom, so none of my “Factory” images will work for you. You can try:
But I don’t think it’ll work, so it’s going to be up to you to program your custom version of u-boot.
In that case, these same rules will apply to your “u-boot, usb mounted” eMMC: https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-SetupmicroSDcard
Regards,
Hi Robert,
I flashed eMMC using Etcher. I am using BBBw dev board for testing, so at this point, all prebuild images are ok.
I will try your version, later.
Very cool tool (nodejs), much easier way to flash eMMC through usb. Thank you a lot for your help!
Best Regards,
David
@ytooui, the AM335x Boot rom should be sending a BOOTP request over the interface.
Take a look at this project for a working implementation:
