ESP32C3 SPI2 crash

[BugSimpson]

When I try to write a value to the register, the controller crashes..
Was I wrong?

Code: Untitled.c Select all

uint8_t spi_write_cmd( uint16_t uiCmd )

{

  // set uiCmd and 7 = bitleng

  REG_WRITE( SPI_USER2_REG, ( uiCmd ) | ( 7 << 28 ) );

}

Code: Untitled.c Select all

spi_write_cmd( 0x01 ); //Transfer Type: Wr_BUF, CMD STATE = 1bit mode, ADDR STATE= 1bit mode, DATA STATE= 1bit mode 

This is the crash File:

Code: Untitled.txt Select all
