Trouble getting the tcp webserver none-os example running.

[Mapy542]

As the title describes, I'm having a bit of trouble getting the none-os, ch32v307 webserver example running on my v307 cheap dev board. I have USB-ISP uploading, but no debugger. I understand the example outputs debugging data on a uart port, working on getting that output piped to USB now. I've modified the main.c to not need a button press to continue on in the program, and I've verified the correct pins are connected to RX/TX. I've tried to add code to the example to blink the onboard LEDs to check that the code is even running, but haven't had any luck. I see the example Readme states the chip must have the correct flash/ram config. When I get board info:
RDPR_USER: 0x609F5AA5 [7:0] RDPR 0xA5 (0b10100101) - Unprotected
[16:16] IWDG_SW 0x1 (0b1)
- IWDG enabled by the software, and disabled by hardware [17:17] STOP_RST 0x1 (0b1) - Disable
[18:18] STANDBY_RST 0x1 (0b1)
- Disable, entering standby-mode without RST [23:22] SRAM_CODE_MODE 0x2 (0b10) - CODE-256KB + RAM-64KB`
Looks correct to me. Is there anything obvious I'm missing? I'm very new to the ch32v ecosystem and this build chain. Thanks!

You don't need to modify the main.c, the PB6 button is just a "restore default config" / reset button. It's a one time thing checked on boot.

The CODE-256KB + RAM-64KB looks good - exactly as required by hte example.

What exact "cheap dev board" do you have? The board referenced in the example expects a high-speed crystal to be present. The example was tested on the board as shown here.

Does the blinky-none-os work fine for the board?

This is the board type I have: https://a.co/d/5QMCapx

It does have the HSE crystal available. I've confirmed that, and I was the one discussing the USB interface issues regarding enabling the HSE. Additionally, the noneos-sdk blink example does work.

Thank you for the response. I've been busy for the last few weeks and have been unable to troubleshoot. I should be able to scope the Ethernet lines for signs of activity soon.

Nevermind, I've figured it out. The netgear switch I was connecting to must not support 10baseT. Using a different network switch it connects, no problem, Thank you for reaching out.
