diagnosing segment linking overflowing dram0_0_bss and dram0_0_seg?
To start with, the FujiNet hardware is fully maxed out. a WROVER-E with 16MB of flash, and 8MB of PSRAM. I have been folding a port of RunCPM into #FujiNet, so that the device can provide CP/M compatibility to an Atari 8-bit computer, alongside its other duties of being a sort of swiss army knife pe...

Re: are TCP DUP ACKs caused by lwIP process being starved of time?
Thanks to the tireless efforts of a FuijNet user (Mark LeAir, aka John Polka), he found an SDK option that fixed our issue: [Codebox] CONFIG_LWIP_TCP_QUEUE_OOSEQ=n [/Codebox] Which turns off queuing of packets that are out of sequence, forcing the host to re-send (which it will anyway), but avoiding...

TCP DUP ACK是否是lwIP进程被饿死造成的?
大家好 我是#FujiNet项目的固件开发者之一,该项目为#Atari8bit电脑带来了网络适配器。 固件在这里,而且是免费软件。 https://github.com/FujiNetWIFI/fujinet-platformio 我们目前遇到的问题是固件中的Wi-Fi MODEM仿真(目前在这里实现:https://github.com/FujiNetWIFI/fujinet-platformio/blob/master/lib/sio/modem.cpp),如果主机发送了太多的一字节数据包(由于主机为了提高交互性能禁用了Nagle算法),那么ESP32对这些数据包的响应速度不够快,主机会重...

are TCP DUP ACKs caused by lwIP process being starved of time?
Hello everybody, I am one of the firmware developers on the #FujiNet project, which brings a network adapter to the #Atari8bit computers. The firmware is here, and is free software: https://github.com/FujiNetWIFI/fujinet-platformio We are currently having issues with the Wi-Fi MODEM emulation that i...

What would cause lwip_close() on a listening socket to return an errno of 11?
The subject says it all. I have a simple server class that was templated from Arduino somewhat: https://github.com/FujiNetWIFI/fujinet-platformio/blob/master/lib/tcpip/fnTcpServer.cpp I am initializing an LWIP socket, binding to it, setting it to listen, and setting it non-blocking/keepalive/reusead...

Synchronous serial I/O?
I am part of a successful project that turns the ESP32 into a super-peripheral for the Atari 8-bit systems, called #FujiNet. http://fujinet.online/ Thus far, we've been using one of the UARTs to communicate with the Atari asynchronously, with POKEY providing its own clock. We are able to use the LED...
