Flashing ESP32-C3-Zero

[lyizb]

Thanks. I tried again with a new C3Supermini, and got the same message. I also see that it says "FlashId: 0xFFFFFF" and "Auto-detected Flash size: undefined" -- I didn't notice if I got something different from the three that I successfully flashed.

These are the last two new ones I have on hand. I have a bunch more coming--I hope they're not the same. I guess I'll need to test them all as soon as they arrive so I can try to get a refund if they don't work.

As per the "Warning about AliExpress ESP32 C3 Mini modules" post, the two ESP32-C3Superminis that failed to flash do not have the "F" line printed on the chip. Too late to get a refund on these two--but I'm wondering about the 12 more I have on order.

This puts a crimp in my plans.

I just bought the C3 Super Mini, they can't be programmed.
This is what I get when I open the console after a hardware reset:

Connecting...
Connected successfully.
Try hard reset.

Edit :
After I pressed the two buttons, it is programmed...
Unfortunately one of the 5 pieces is defective, doesn't the IP ADR come via ser?

If you flashed the module with the USB version, the IP comes via the USB serial; you can use the WEB Serial Terminal for that

Oh, thanks, otherwise HTerm always worked.
Could I also provide a link to the UDP / Modbus Testprg Annex CAM Toolkit receive.
That also seems to be a big help.
Overall, I'm thrilled with this little thing. If i can actually increase the antenna performance, great.

Yes, do not hesitate to provide the link.

If you are talking about the utility that is reported [Local Link Removed for Guests] , this is an old toolkit I developed some time ago that is not supported anymore.

I think someone continue to use it but I stopped to support it

But the tool looks good, with many options from a single source, it's a shame that it's not available.
Best regard, Helmut

If you want try, the toolkit is available [Local Link Removed for Guests] but take into account that the annex .bin included inside are obsolete. You can use the other utilities but always use the online flasher for flash / update the modules.
