Hi,
I'm trying to configure Timer5 as PWM, but no signal is output on timer 5 pin.
my slice of code is:
#define CM_ALWON_L3_SLOW_CLKSTCTRL (*(volatile unsigned long *)0x48181400)
#define CM_ALWON_SYSCLK4_CLKSTCTRL (*(volatile unsigned long *)0x48181420)
#define CM_ALWON_TIMER_5_CLKCTRL (*(volatile unsigned long *)0x48181580)
#define CM_TIMER5_CLKSEL (*(volatile unsigned long *)0x481803A0)
#define PINCTRL203 (*(volatile unsigned long *)0x48140B28)
#define PINCTRL204 (*(volatile unsigned long *)0x48140B2C)
#define PINCTRL205 (*(volatile unsigned long *)0x48140B30)
#define PINCTRL206 (*(volatile unsigned long *)0x48140B34)
#define TIMER5BASE ((volatile unsigned long *)(0x48046000))
#define TLDR (*(volatile unsigned long *)(((unsigned long)TIMER5BASE) + 0x40))
#define TMAR (*(volatile unsigned long *)(((unsigned long)TIMER5BASE) + 0x4C))
#define TCLR (*(volatile unsigned long *)(((unsigned long)TIMER5BASE) + 0x38))
#define TTGR (*(volatile unsigned long *)(((unsigned long)TIMER5BASE) + 0x44))
#define IRQENABLE_CLR (*(volatile unsigned long *)(((unsigned long)TIMER5BASE) + 0x30))
#define TIOCP_CFG (*(volatile unsigned long *)(((unsigned long)TIMER5BASE) + 0x10))
void setupTimer(void)
{
CM_ALWON_SYSCLK4_CLKSTCTRL |= (1<<10); // enable L3 slow clock
CM_ALWON_L3_SLOW_CLKSTCTRL |= (1<<24); // enable TIMER 5 clock
CM_ALWON_TIMER_5_CLKCTRL = 0x00000002; // enable TIMER 5
CM_TIMER5_CLKSEL = 0x00000002; // choose CLKIN 27MHz for TIMER 5
// setting up pin multiplexer
PINCTRL204 = 0x00000000;
TIOCP_CFG = 1<<2; // no-idle
IRQENABLE_CLR = 0x00000007; // disable interrupts
TLDR = 1000; // load register
TMAR = 0xFFFFFFFF - 500; // match register
/* control register:
PT = 1 (toggle)
TRG = 2 (trigger on ovf and match)
TCM = 0 (no capture)
SCPWM = 0
CE = 1 (Compare mode)
PRE = 0 (no prescaler)
PTV = 0
AR = 1 (auto reload)
ST = 1 (start timer)
*/
TCLR = 0x00001843; // control register
TTGR = 1; // TRIGGER
}
where am I wrong?
best regards
