Re: ESP32 BUG cause software brick
Damn. Maybe it's not related to core dump then, I was just going on the last log message before it froze. I don't know of anything in particular with this commit, but this is the problem with "Development" versions (-dev) - they have had some basic automated testing but they're not comprehensively ...

Re: ESP32 BUG cause software brick
Got it, thanks. If you now do "esptool.py erase_region 0x3a6000 0x32000", without changing anything else, does the firmware finish booting correctly? No, I deleted that partition with its specific size and at the first boot, an error message appeared while loading the partition table, but as soon a...

Re: ESP32 BUG cause software brick
It looks like maybe there is some problem with the core dump partition in flash? Is there any chance you could dump this partition with "esptool.py read_flash" and then send it to me? BTW, you say you ran the code for more than 1 year but it looks like you've more recently rebuilt the project with ...

Hi guys, something crazy happen with my esp32 product... I was testing our product in my home (I brought it from work) and turned on the power, everything working normally.

Re: task watchdog user handler
Not really... usually, when a stack overflow happens, it is detected after the fact and random data from other tasks or the OS already has been overwritten. This means the stability of the system can't be relied upon anymore and it would not be a smart idea to do complicated stuff like uploading lo...

Re: task watchdog user handler
It's because c/cpp files will be left out entirely if they don't contain any symbols that are unresolved, and the linker sees the availability of a 'weak' function as 'resolved'. Solution is to create a symbol in the c file somehow (e.g. void wdt_handler_dummy_symbol { }) and then add ing a linker ...

Re: task watchdog user handler
Well, I using .cpp file in main esp32, then, weak function will not work without 'extern "C"'

But, how can I get task name that not-feed task wdt in this handler()?
this work's nicelly:
Code: Select all
extern "C" void esp_task_wdt_isr_user_handler(void)
{
ets_printf("lol\r\n");
}

ESP32 BUG with Battery backed & BOD + RTC ON
Hi little guys! I found bad notices about esp32 with power supplied by (old) litio battery. I keep esp32 powered by battery until battery die (~2.1V) just to test, but sometimes, esp32 not turn on even I put power supply (providing to battery & circuit)... Putting esp32 in serial debug to view ROM i...

Re: Is it safe to read and write UART from different tasks?
Looking just at uart.c, apparently YES, but anyone can really confirm if all uart tx are safe?
