When I try to write a value to the register, the controller crashes.. Was I wrong? uint8_t spi_write_cmd( uint16_t uiCmd ) { // set uiCmd and 7 = bitleng REG_WRITE( SPI_USER2_REG, ( uiCmd ) | ( 7 << 28 ) ); } spi_write_cmd( 0x01 ); //Transfer Type: Wr_BUF, CMD STATE = 1bit mode, ADDR STATE= 1bit mod...

perfect, thank you.
It was really because the Spi2 unit was in a reset state, which according to the data sheet it shouldn't be in a reset state

you mean the "SYSTEM_SPI2_CLK_EN" Bit? (see Pic.)
it is enabled..

i try to connect gpio2 to gpio5 (only for testing) but its still working, what make i wrong? #define pin_number 2 #define io_signal_out CPU_GPIO_OUT5_IDX //Connect the pin to the GPIO matrix. PIN_FUNC_SELECT(GPIO_PIN_MUX_REG[pin_number], PIN_FUNC_GPIO); //Set the direction. GPIO_MODE_INPUT always ma...

Hello,
Can someone explain to me why I can't read a register from the SPI2 controller? No matter which register is read, a 0 is always returned. I read the date register from the gpio controller and the value matches.

anyone have an idea?
