Stm32 libopencm3 STK_LOAD undefined?

Question

Programming

Throws STK_LOAD undefined
"int main( void ) {
rcc_clock_setup_in_hsi_out_24mhz();
systick = 0;
STK_LOAD = (uint32_t)(24E6 / 1000 / 8);
STK_CTRL = STK_CTRL_CLKSOURCE_AHB_DIV8|STK_CTRL_TICKINT;
STK_CTRL |= STK_.....ENABLE;
"...... ENABLE; .piece of code

Answer 1

In systick.h it is written like this:

/* --- SYSTICK registers --------------------------------------------------- */

/* Control and status register (STK_CTRL) */
#define STK_CSR				MMIO32(SYS_TICK_BASE + 0x00)

/* reload value register (STK_LOAD) */
#define STK_RVR				MMIO32(SYS_TICK_BASE + 0x04)

/* current value register (STK_VAL) */
#define STK_CVR				MMIO32(SYS_TICK_BASE + 0x08)

/* calibration value register (STK_CALIB) */
#define STK_CALIB			MMIO32(SYS_TICK_BASE + 0x0C)

Maybe try putting STK_RVR instead of STK_LOAD ?

Answer 2

there is such a file (somewhere on habré I dug up how to set up sublimtext for assembly and there was a project)
it collects but the size is 0 in all parts
