Hi Murat, The bringup procedure for esp32-wrover-kit does not initialize the character device driver for any SPI channel. Please, take a look at the code for the esp32-devkitc board: https://github.com/apache/incubator-nuttx/blob/master/boards/xtensa/esp32/esp32-devkitc/src/esp32_bringup.c#L398-L407
Best regards, Gustavo.
