Guru Meditation Error: Core 0 panic'ed (Cache disabled but cached memory region accessed)

Hi all,

I have a requirement like set/reset the gpio pin based on the condition, which is in timer interrupt of time 10ms and in parallel I'm receiving data from uart interrupt and that data I'm writing it to internal flash using spi_flash_write() API function. when spi_flash_write() function is called, I'm getting an error "Cache disabled but cached memory region accessed". Can anyone help me to solve this problem?.

Any help can be appreciated.

Thanks

hi

you use timer and writing data to internal flash ( SPIFFS? )
you use in arduino ? IDF ?

Hi
thanks for the reply.
I'm using internal flash(spi_flash_write/read/erase API's).
I'm using ESP-IDF 5.2 version.
