Esptool.py indeed only supports bin files, so you'd need a program (you could likely use objcopy for that) to convert the srec into a bin file. I don't know how your particular otap implementation works, if it means the ESP receives SREC data, then you need some kind of code to convert that back to ...

Can you explain a bit more what you're trying to do, as in, what's in that srec file that you want to flash and why do you want to flash it? Generally it's unlikely that that srec has anything in it the ESP can run as it's not a common format for ESP binaries.

Your post seems to be lacking the image.

It tells you the issue:
Make sure your spiffs partition size is a multiple of 4096 bytes and this should go away.

That might be a known issue. Can you put the ESP32 in download mode (by lowering IO0 and hard-resetting the board) and try uploading again?

'ESP32-S2FNR2' and 'esp32 s2 mini' are names of the chip and the module, not the devboard, hence me asking. Also, that ali link doesn't quite work for me.

The examples are there to get people started; as you say, it's hard to get the setup of things 100% correct first try if you're unfamiliar with APIs etc, as the full capabilities of some APIs can be overwhelming. From my experience, once you have some feeling for the APIs, you can generally whip the...

Again, EN connected hard to 3.3V is not something that is in spec: unless you give the ESP32C3 a good power-on reset via e.g. a RC-network on EN, unexpected things can happen (because some parts of the chip may be in latchup, for example). Not saying that that this is absolutely the cause for this b...

The ESP32 uses the windowed ABI; rather than callx0 you should use one of callx4, callx8 or callx12. Note that if you want to pass arguments to the C function, this also shifts the registers these argument are passed in.

Is it because there is no Analog Function on ESP32-S3 GPIO 41?

Exactly that. If you want a pin with an ADC function, check the ESP32-S3 datasheet and pick one of the pins that also have ADC1_CHx as a function. (ADC2 is not really usable on the S3 iirc.)
