Re: vApplicationStackOverflowHook with custom partitioning and 4MB flash size

What does the code do; is there a possibility you actually have a stack overflow somewhere? Why do you think the partitioning is related?

Re: Where are ESP engineer?.............................?.........................?

I think you misunderstood the purpose of this forum. Its main intent is for ESP32 users to help eachother; engineers can chime in if they aren't otherwise occupied; first and foremost, this is not a helpdesk. You already got a response in the other topic; suggest you follow that. In general, if you'...

Re: Code building of ESP32

That works for libraries that are actually intended for use as esp-idf components. If they're not (and yours don't seem to be), you need to add the required plumbing to have esp-idf compile the library yourself. Again, see the link I posted earlier for info on how to do that.

Re: ESP 8089 still supported

bbs.espressif.com is our ESP8266 forum, but that's also not really for the 8089... you may have better luck inquiring sales@espressif.com, see if they have something they can share.

Re: ESP32 I2S camera slave mode I2Snl_Data_in Can be set to 1-bit/2-bit/4-bit?

Not exactly... if you need 1-bit, you may be able to fake something using the normal (non-camera) I2S mode. If you need 2 or 4-bit modes, perhaps the dual-SPI/QSPI modes of the SPI peripherals can do what you need.

Re: Question re: sub-microsecond timing, performance tuning

In general, trying to do tight timing loops on the ESP32 is not advised - there's a RTOS running in the background, there's caches being refilled, there's all sorts of reasons for jitter. If you can, use a peripheral that's specifically intended for it - MCPWM, for instance, is very good with motors...

Re: ESP32 First boot

You do need an external crystal, I don't think the ESP32 can boot up from the internal oscillator. Furthermore, you probably need a flash chip to store your program in, as well as the stuff around CAP1/CAP2, plus perhaps more; check here for more info.

If I could, I'd have done so in the post above, sorry.
