Re: Load code to certain regions of the flash

FWIW, I've been looking at this a little longer. In essence, normal OSses also have this problem because a program in e.g. Linux has to be able to load multiple shared libraries per process, so the shared libraries can't use fixed addresses for their static/global variables. That is solved in one of...

Re: questions/Issues with custom implementation (Xtal, jtag, etc..)

rezarethink: No clue why VisualGDB doesn't do the right thing; my guess would be that it expects some kind of firmware to pre-exist in flash that initializes CPU1. Maybe you're better off asking the VisualGDB people this. On why the serial port does not work: Are you sure you're pulling down GPIO0 a...

You are aware that the WROOM-02 contains an ESP8266, not an ESP32? Do you mean the WROOM32?

Re: Can I run non freeRTOS code on one core

In the current setup, unfortunately having your own code running on Core1 exclusively is sort-of hard: there are some things where the hardware requires cooperation between the two CPUs. From memory, one of those things is writing to flash (which disables the flash cache, which can make the program ...

Re: Compile error with Compiler options - Optimization Level (Release (-Os))

I seem to remember that we ran into and solved these issues a while ago... are you sure you're on the latest master? If not, can you do a git pull and a git submodule update and see if you still get this?

Re: Any news on ADC linearization?

Agreed. We're still working on it; hope to have the first code for it in esp-idf master within a few weeks.

Re: uart uart_set_pin forces me to set rts and cts, how to avoid losing gpio?

No need to. You can pass UART_PIN_NO_CHANGE as the pin number for the pins you do not want to use, and the uart code will not claim a GPIO for those.
