Raspberry pi 3 pxe boot windows
Каждая версия плат Raspberry делает это по-своему.
Raspberry Pi 4b
В Raspberry 4 появилась обновляемая прошивка загрузочного кода в процессоре. С завода загрузка по сети отключена. Чтобы включить, надо обновить прошивку. Скачайте отсюда: wtware.com/files/raspberry/ архив pi4netboot-eeprom-nnn.zip свежей версии. Распакуйте на чистую SD. Загрузите Raspberry 4. Если всё получится, через несколько секунд зеленый индикатор начнет часто моргать. Можно выключать и доставать SD. Прошитая таким образом Raspberry 4 будет загружаться только по сети. Чтобы вернуть обратно загрузку с SD, надо скачать там же архив pi4default-eeprom-nnn.zip , распаковать на SD, загрузиться с этой SD. Другой вариант вернуть загрузку с SD в разделе Recovery на официальном сайте Raspberry.
Не стоит загружать Raspberry 4 по сети, если используется локальный Google Chromium, особенно если у Raspberry только один гигабайт памяти. Chromium очень большой. При загрузке по сети все файлы Chromium будут храниться в памяти, и для работы её останется совсем мало. Загружаясь с локальной SD, WTware распакует много файлов на SD, и свободной памяти останется больше.
WTware DHCP знает, что надо Raspberry для загрузки по сети. Если вы используете другой DHCP, нужно указать в 066 параметре DHCP IP адрес TFTP сервера.
Raspberry игнорирует 067 параметр DHCP и всегда загружается из корня TFTP или из каталога, соответствующего серийному номеру Raspberry. WTware TFTP знает об этом и загружает на Raspberry ту версию WTWare, которая указана в Конфигураторе. Если вы используете другой TFTP, придётся смотреть в логах вашего TFTP, где Raspberry ищет загрузочные файлы. Используйте дистрибутив WTware в zip, в нём правильная структура каталогов.
Если понадобится внести изменения в файлы config.txt или cmdline.txt для одной Raspberry, которая загружается с WTware TFTP, скопируйте его из каталога (вместо 6.0.4 укажите версию WTware, с который вы работаете): в каталог терминала: И в каталоге терминала уже вносите изменения, нужные только для этого терминала. WTware TFTP сначала ищет файлы config.txt или cmdline.txt в каталоге терминала, и если не находит, тогда отдаёт стандартные файлы.
Raspberry Pi 3b+
Мы не рекомендуем загружать Raspberry 2b, 3b и 3b+ по сети, если ваша сеть сложнее одного свича, который соединяет сервер и несколько Raspberry. Загрузчики Raspberry до четвертой версии содержат ошибки. Помимо ряда проблем, проявляющихся в «Raspberry не загружается», при некоторых условиях во время загрузки по сети Raspberry 2b, 3b и 3b+ используют чужие IP, не те, которые им выдал DHCP, нарушая работу тех, кому эти IP принадлежат.
Raspberry 3b+ загружается по сети только когда в ней нет SD карты. Или не загружается, тогда конкретному экземпляру Pi3b+ ничем нельзя помочь.
Pi3 retry network (PXE) booting #825

Can the Raspberry Pi 3 be programmed to retry network booting if it fails to boot the first time? We have some Raspberry Pi 3’s at remote sites and if a power outage occurs, the Pi requests an IP-address through DHCP before networking equipment is fully up and running. This means the DHCP-request goes unanswered and the raspberry pi sets itself to USB device mode, then waits.
Is it possible to reprogram the Pi to retry network booting after a failed attempt and not switch to device mode? Or does this require reprogramming the boot ROM (which, as I understand, is not possible as it is readonly and part of the SoC)?

We are booting a bunch of slave rpis from a master rpi and have a similar problem described above.
We currently have to boot the master first and then the slaves once the Master has booted. A way to allow the slaves to wait a time before booting — or to retry would be nice. We are using the bootloader.bin on the SD card to avoid setting the OTP flag at present so in theory this could be updated to accommodate our needs, only we cannot do this due to the closed nature of some parts of the RPi and thus need to ask someone who reads these issues and can do it to look at this for us.

This would be really useful. Especially in enviroments with a STP-switch.
popcornmix commented Jul 17, 2017 •
Without an sdcard present this is impossible as the bootrom can’t be changed.

@timmmmmey
Usually there is something like «portfast» (Cisco names it that way), which could be used as a workaround.

This is also biting us. We’re shipping integrated units with pis behind a switch that takes some time to come up — currently when the unit is power cycled, the pis attempt to boot before the switch (which provides access to PXE resources) is ready, and we have to wait for a hardware watchdog to reset the pi.
@popcornmix we use SD cards with an updated bootcode.bin, as the bootrom bootcode.bin doesn’t function reliably. Thus we could resolve this with updated SD cards.

bootcode.bin option for sticking permanently with ethernet sounds like an easy thing to add. What release of bootcode.bin are you using at the moment?
mikemccabe commented Nov 7, 2017
Thanks for your reply!
We’re using the bootcode.bin from the 2017-09-07-raspbian-stretch-lite release.
$ shasum bootcode.bin

ghollingworth commented Nov 13, 2017
Can you try following the instructions and using the bootcode.bin attached to the Wiki to get UART debug out?
mikemccabe commented Nov 15, 2017 •
Hi, I’ve set this up.
Did you also change the logic in that bootcode.bin? Things seem to work now! Will you be incorporating these changes into the mainline bootcode.bin?
Booting fails in my test setup with the older bootcode.bin.
My test setup: Pi is connected to PXE server via an intermediate switch powered on after boot starts, thus DHCP may fail for a time even though the link is up.
Here’s the dump: (note I added a timeout file, likely irrelevant here)
Raspberry pi 3 pxe boot windows
A ready-to-go PXE + TFTP network boot server for Raspberry Pi, with Resin deployment.
Want to boot a machine from the network, don’t want to have to fight with all the configuration and setup yourself, and have a raspberry pi to hand? This is the solution.
- Set up your device, with reliable power, a network cable, and optionally wifi (if you want logging or easy access).
- Sign up for free on resin.io, create an application, and provision it, optionally with your wifi credentials.
- Set the following environmental variables:
- RESIN_SUPERVISOR_DELTA: 1 // Enables deltas for updates keeping later changes quick
- Clone/fork this repo, and push it to your resin.io application’s repository to deploy this setup.
- Set up your specific PXE config over samba (to /tftp), SCP (to /data/tftp), or over tftp by:
- Uploading your PXE bootable image
- Adding your PXE config at pxelinux.cfg/default
- You’re ready to go: put the device on the same network as the target machine (directly or through a router, as long as DHCP is disabled on the router), tell that target machine to boot from the network, and enjoy.
You can change and push a new Dockerfile to your application if you want to carefully update your device to do this differently, or for quick changes there’s an SSH port exposed that allows root login with the default password of ‘resin’.
For the specific Windows boot process this was tested with, scripts are included. See app/windows/setup-windows-pxe.sh in this repo (in /usr/src/app on the device) for full details.
- Builds a Windows PE image from a full Windows image.
- Mounts the full Windows image within the Samba share to make it accessible.
- Makes the Windows PE image bootable through PXE.
To run this script:
- Copy a Windows iso across to the device, either via samba or scp.
- SSH into the device
- Run /usr/src/app/windows/setup-windows-pxe.sh
Once this is complete, any machine attached to the device should now boot into Windows PE, from which you can start the full Windows install process.
Note that it seems Microsoft’s iso download process makes it easy to end up with corrupted iso’s, which will typicall start up, but refuse to install. To check for this, run md5sum on your iso to get its md5, and google for the hash. Any valid official image should return a huge number of related results.
This setup has pretty much no security — do not connect this device to any untrusted network (e.g. the public internet). Root SSH is set up with a default password, and file sharing services are configure with public read/write access to the image you will be booting from. That’s super convenient and effective if the device is only connected to you, but it’s trivial complete control of both the device and the machine you’re booting from if anybody else can connect.
- Device will run as 192.168.0.1, and provide DHCP for the rest of the 255.255.255.0 range.
- DHCP and TFTP configuration are done with Dnsmasq, see dnsmasq.conf ( /etc/dnsmasq.conf on device)
- TFTP is preconfigured for BIOS PXE, using files from syslinux and pxelinux (see Dockerfile.template for details).
- A samba share is available, see smb.conf ( /etc/smb.conf on device)
- Direct SSH access is available to examine and change the device at runtime, or transfer files over SCP.
I’m open to PRs for these, but I don’t need them myself right now, so they won’t happen without help.
- Preprepared config/scripts for other scenarios.
- Allow setting a BOOT_IMAGE_URL environmental variable for a URL to get the boot image from.
- UEFI boots. I don’t know much about this, but I know this currently supports only BIOS PXE. I believe most current motherboards support this, sometimes with an option like LAN Boot Rom , but for very new machines/in future this may not be true.
