esp32-s3 mini purple Lolin

Post by peridot »

I am just about ready to bin these two modules I have as I cannot flash them successfully but I keep coming back to them trying another approach as I am convinced I is something I am doing/not doing :oops:
The most success I have had , at least it talked to me, is using the toolkit and using a serial adapter. This what I get on the serial port, anyone had this and went on to successfully flashing them? or is it time to Bin :(

Hi,
first of all are you sure that your modules are ESP32-S3?
I suppose that the modules are very probably ESP32-S2.

I suggest to use the online flasher [Local Link Removed for Guests] and try to flash with it.

In the worst case you should be able to identify the kind of modules that you have

Here you go,

Tried with the web flasher exactly the same result. I would really like to find I am doing something wrong but ...I am afraid I think they are stuffed.

My suggestion is to try using the rest and boot buttons in the normal order. Other people have had trouble with this board - e.g. read this thread.

As a last attemp, try a different USB lead.
I have one lead and one board which when used together always keep resetting when trying to update the firmware.

Alors, this module is not supported.
It is an ESP32-S3 with 4MB of QIO flash and 2mB of QIO PSRAM; additionally it has a direct USB connection (no USB to serial converter integrated) like the some of ESP32-S2.
It requires a firmware QIO_QSPI
It should work with the firmware 1.50.5 CAN_qio_qspi_LFS but you'll not have any activity on the USB as the firmware will use the serial link on the TX and RX pins; in this case you should be able to use it via the web interface.

So I suggest to load it and see if you can find its AP access point.

Perfect cicciocb :D That did the trick, good job I asked before binning them, It must give you an headache keeping up with all these different versions!
I assume I will have to stick with that version?, that's fine they at least work.

Thanks again, Mike

Nice to see that my hypothesis was correct; you can eventually use the serial port with an external USB to serial adapter.
I plan to publish an updated version in next days so I'll include also this variant.
