Core 0 panic'ed (Interrupt wdt timeout on CPU0) when i have tx ring buffer

[Melika]

Hi every one.i have problem with uart_driver_install in espidf.when i use uart driver install like uart_driver_install(Serial0,1024,0, 10, &uart0_queue, 0) my rx interrupt works correct but if i want to use write something on serial with uart_write_bytes() i get "Core 0 panic'ed (Interrupt wdt timeout on CPU0)" error. i know that if i use driver install like uart_driver_install(Serial0,1024,1024, 10, &uart0_queue, 0) ,uses tx ring buffer and write faster on serial , but when i use like this i cant write anything on serial.
how can i solve this?
my espidf version is 4.4.6

Generally, you can't both use the UART driver and use your own ISR. The driver needs the ISR to function to work.

Hi.thanks for answer.if i enable just tx interrupt,i get error .do you know how can i have tx interrupt ?
