I did overload the weather station with OTA and now also adding interrupt timers seems to be a little bit too much:

Could you please confirm if this is too much for such a system or do you see a chance to get this fixed?

I did try to get the core dump with different serial speeds, but w/o success.

I’m stand-by for all of your suggestions,

Uoopsie! – I did try Sketch>Digital>Blink with the very same board and stil get the error:

configsip: 0, SPIWP:0xee

clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

mode:DIO, clock div:1

load:0x3fff0030,len:1344

load:0x40078000,len:13924

ho 0 tail 12 room 4

load:0x40080400,len:3600

entry 0x400805f0

E (137) esp_core_dump_^X.K�ɕ�dump data check failed:

Calculated checksum='d0023cc9'

Image checksum='ffffffff'

Apart from the error message in the serial console, the device does it’s job. – So I simply keep ignoring the error for now. J (I am not a professional and simply can do that. ha, ha!)

Hi.
Maybe you need to “clean” the flash memory.
Take a look at this: https://randomnerdtutorials.com/esp32-erase-flash-memory/

I hope this helps.
