Hi,
I got the timer-app.c demo code working, but when I tried to write my own firmware and flash it to the SPE, I always got stuck on this line:
[ 6.7983 ] tegrarcm_v2 --isapplet
Here is the code that I’m trying to run. What I’m trying to do is to start a timer inside the timer callback, so that I can get the timer to trigger on a desired time.
17 void PPS_timer_callback_1(void *data) {
16
15 uint32_t usec, osc, tsc_hi, tsc_lo;
14
13 usec = tegra_tke_get_usec();
12 osc = tegra_tke_get_osc();
11 tegra_tke_get_tsc(&tsc_hi, &tsc_lo);
10
9 uint32_t next_stamp = get_next_stamp(usec, STEP);
8
7 printf_isr("Timer2 irq triggered, usec = %lu, osc = %lu "
6 "tsc_hi = %lu, tsc_lo = %lu, next_stamp = %lu\r\n",
5 usec, osc, tsc_hi, tsc_lo, next_stamp);
4
3 // calculate new timer duration and setup the timer
2 uint32_t timer_last = next_stamp - usec;
1 tegra_tke_set_up_timer(&tegra_tke_id_timer2, TEGRA_TKE_CLK_SRC_USECCNT,
64 false, timer_last, PPS_timer_callback_2, 0);
1 }
2
3 void sensor_trigger_init(void) {
4 tegra_tke_set_up_timer(&tegra_tke_id_timer1, TEGRA_TKE_CLK_SRC_USECCNT,
5 false, PPS_INIT, PPS_timer_callback_1, 0);
6 }
The code compiled just fine but can’t get flashed into the Xavier. Any idea why would cause that? Thanks!
