Эмулятор CD-ROM из Raspberry Pi Pico W, использующий образы из сети

В одной из своих статей я уже рассказывал, как из Raspberry Pi Pico сделать USB CD-ROM. Так как размер флеш-памяти Pico ограничен, поместить что-то серьёзное в образ, который будет находиться во флеш-памяти невозможно. Можно попробовать разместить образ на флеш-карте и использовать модуль для неё, но я нашёл более интересное с точки зрения используемых технологий решение. Эмулировать образ, который находится в интернете. Образа многих дистрибутивов Linux доступны для загрузки с сайта.

Ethernet, TCP/IP and Ping | STM32 Tutorial #91

This video introduces our new Ethernet Blade and get a TCP/IP stack (LWIP) up and running to a point where it respond to ping.

#IPv6, #EUI64 und #IoT

Ein deutscher Heizungshersteller bietet ein IoT Connector für seine Heizungen/Wärmepumpen an. Dieser kann DualStack (yeah) allerdings EUI64 GUA (😭 ).
DNS ist #IPv4only A/AAAA Queries und im Moment sind alle Endpunkt für APIs #IPv4only weil #azure

Was können wir tun, damit #lwIP #RFC7217 #RFC8981 kann?

Uvoks daily struggle.

"Huh?? Why does the LwIP stack send an ACK for a second incoming TCP connection?? I only accept one at a time!?!?"

Apparently, that's a "backlog", and it's suffering you can't turn off completely.
If I really want to only work with one client at a time, I probably have to accept and close the other sockets immediately?

(No, setting backlog to 0 on listen doesn't help)

#esp32 #lwip #networking

Accessing #lwip directly seems to work pretty ok already.

Now I'm trying to see how far I can implement rudimentary #Arduino framework compatibility (before losing interest in the tedium).

After some hours, the EthernetClient finally behaved enough for a simple TCP echo test :D

#WCH #CH32 #CH32V208

Progress of the night: Getting the essentials of the #lwip stack running on the #CH32V208.

Still need to clean it up _a lot_ and build the wrapping library, so it's actually useful.
But seeing lwip run at all is amazing.
(So I don't need to depend on the proprietary, closed source #WCHNET library)

Good night :D

#WCH #CH32

@cv Everything except #lwIP and the FatFS library. But i'm going to replace the FAT library with a driver that is able to handle asynchronous I/Os. Network is working super well tho, lwIP is very Zig-compatible.

All apps, kernel and so on is written in pure Zig, and it's very convenient

@lupyuen When I notice that I started depending on your network library as if it were an OS (using its timer chains and memory slabs). Then I went from #lwIP to @RIOT_OS
