Re: ESP32 Boot Loop (ESP-IDF)

What hardware setup, specifically which means of power supply are you using?

Re: About the CAN controller.

Nice! Thank you very much. I'll see if we can integrate it into esp-idf.

Re: Boot loop problem

You basically ran into an internal assert, that is, the ESP32 detected some software condition that should never ever be there, but may have occurred because e.g. memory got corrupted. Can you try 'make clean' before re-making it?

Re: Unhandled Interrupt!

I tried to reproduce this, but I just get a lot of 'Loop' prints on my screen, as expected. Do you still get this result with the latest esp-idf? (Run 'git pull; git submodule update --init' to update.)

Re: Plans for complete BLE stack (ATT, GATT, etc)

They actually have, but because of (amongst others) the closed-source nature of the stack, we'll only be using the lower-level bits of it. For the higher layers, we have a port of Bluedroid in the works which is fairly close to completion (eta of inclusion in esp-idf: a few weeks)

Re: Physical block size and physical page size of SPI flash for SPIFFs

In general, though, I'd say that a rough estimate of 99.8% of all chips the ESP32 can interface with use the same block/page sizes (256byte page size, 4KiB erase block size)

Re: Static library - call target out of range

Do you compile the lib from source? If you add the source as a component to your esp-idf project, it should work just fine. If not, maybe whatever C-flags you use aren't compatible with what esp-idf expects.

Re: [Solved] Using the RMT peripheral ...

Depends on how creative you are with abusing the peripheral :P I'm sure you can get something working. I'd think VGA may be a bit hard, though, because the channels in the RMT aren't entirely independent (they can't access the memory at the same time) so you will have some pixel skew between the r, ...

Re: Need help to download firmware into ESP32

RoundRobin: Do you happen to have GPIO12 connected to something? Can you try disconnecting that pin?

Re: Does the Esp32 support hardware based I2C or software bit-bang based I2C ?

As stated a whole bunch of times before: You can select the pin using the GPIO mux. Please, please, read up on the GPIO mux and how it works. The code you quote does not indicate any specific GPIO use, I2CEXT0_SDA_OUT_IDX etc are the signals you can route in the GPIO mux. Check the last example of i...
