Hi, I am currently looking at using the two pwms in tiny6410 to run 2 stepper motors. I have got PWM0 working using the mini6410_pwm.c driver provided by friendly arm. But I am facing trouble using both simultaneously. It would be a big help if anyone can provide a working example of this. Code to generate signal on PWM1 would also greatly help. code used for PWM0 : tmp = readl(S3C64XX_GPFCON); tmp &= ~(0x3U << 28); tmp |= (0x2U << 28); writel(tmp, S3C64XX_GPFCON); tcon = __raw_readl(S3C_TCON); tcfg1 = __raw_readl(S3C_TCFG1); tcfg0 = __raw_readl(S3C_TCFG0); //prescaler = 50 tcfg0 &= ~S3C_TCFG_PRESCALER0_MASK; tcfg0 |= (50 - 1); //mux = 1/16 tcfg1 &= ~S3C_TCFG1_MUX0_MASK; tcfg1 |= S3C_TCFG1_MUX0_DIV16; __raw_writel(tcfg1, S3C_TCFG1); __raw_writel(tcfg0, S3C_TCFG0); clk_p = clk_get(NULL, "pclk"); pclk = clk_get_rate(clk_p); tcnt = (pclk/50/16)/freq; __raw_writel(tcnt, S3C_TCNTB(0)); __raw_writel(tcnt/2, S3C_TCMPB(0)); tcon &= ~0x1f; tcon |= 0xb; //disable deadzone, auto-reload, inv-off, update TCNTB0&TCMPB0, start timer 0 __raw_writel(tcon, S3C_TCON); tcon &= ~2; //clear manual update bit __raw_writel(tcon, S3C_TCON); I dont require dead zone and DMA. Thanks in advance, Harsha
