Re: JTAG debug issue with v3.0rc1

You may be right there... I think we removed the feature to halt on the first task that starts because we added functionality to halt at CPU reset to OpenOCD at a certain point. You may want to look into updating your OpenOCD setup.

Thanks for your contribution... although I'm sure 'ESP32' is on a few lists now :X

Re: Debugging ESP32 resets

You can use xtensa-esp32-elf-addr2line to look up the line for that PC. Alternatively, if you use `make monitor` as a terminal, it'll do that for you as soon as the address scrolls by.

Re: interrupt still triggered after interrupt service has been disabled

Just wondering: Are you sure those interrupts stem from GPIO26? If for whatever reason, any of the other GPIO pins are pulled low, you'd also see this behaviour. Asking because I just took a look at the GPIO int code, and it seems simple enough that I couldn't spot any obvious bugs that could genera...

Re: Dual core

It depends on how you want to architect your application. There are a few things to take into account: 1. the cost (CPU-wise) to create and delete a task, 2. the total memory usage of your app, 3. the risk you want to take wrt 'over-booking' your RAM. For 1, it's pretty simple. FreeRTOS lives under ...

Re: ESP32 can't into IRQHandler

Suggest you check the return values of all the uart_* calls you make; I bet one of them is trying to tell you you've made an error somewhere but you just throw away that information.

Re: interrupt still triggered after interrupt service has been disabled

Can you post a representative sample for the code that does that?

Re: binary semaphore doesn't work if created in task that uses it ?

Do you get the same weird behaviour if you pin the task to CPU 0 instead of 1?

Re: UART ISR

You cannot run any function that is not specifically specified to be compatible with ISRs in an ISR. Printf is not one of these functions, so it'll crash.
