Hi, I am running freertos on 2 cpus - at one customer site I see occasional errors such as the following, sometimes with TG0 and sometimes with TG1, and every so often the board even locks up (but that's w/o any errors whatsoever). The stack pointer printed often points to a "Double Exception". I wa...

Someone from ESP? Help?

Do you get any wifi messages? Usually the wifi problems are the other way around because wifi connectivity draws more current than usual, so if power is provided via USB, the voltage drops. Are you sure the Vin is at correct level?

I had similar problem - not sure why this happens but it seemed to go away when I changed the configuration parameter in menuconfig -> component config -> ESP32 -> Timer used for gettimeofday from RTC & FRC to just RTC.

However, I don't really understand the FRC and RTC interactions.

Hi, I'm running ESP32 w/ 2 CPUs. Occasionally, I get a WDT resest: W (85) boot: PRO CPU has been reset by WDT. W (85) boot: WDT reset info: PRO CPU PC=0x40084d50 W (86) boot: WDT reset info: APP CPU PC=0x40088214 Looking at the two addresses in gdb: (gdb) list *0x40084d50 0x40084d50 is in spi_flash_...

BTW, this problem only manifested in master - after regressing to version 3.0.1 it no longer appeared

Yes thanks - am aware of that but the version of arduino that includes this new interrupt-driven i2c code requires an unreleased version of the esp-idf, which introduced other issues in our application.

The technical reference manual has a pretty good description. E.g. how the address mapping works, various types of embedded memory, etc.

Thanks - yes, I also generally seem to not have any problems until I do a bunch of modbus and mqtt activity although I'm not sure why that is - it's possible, I suppose, that one of those tasks is corrupting memory. The i2c code is as follows - two methods called at the top level are to "check the i...
