I was trying to schedule a work item when a struct k_poll_signal is raised by an interrupt, but was unable to get the work to happen. I could tell that the k_work_poll_submit function was completing without error (0), same for k_poll_signal_raise.
So I have the following relevant data, and initialized:
typedef struct
{
...
struct
{
struct k_poll_signal UTCDone;
} PollSignals;
...
struct k_work_poll UTCReadWork;
} AppStatus_t;
AppStatus_t AppStatus;
struct k_poll_event UTCEvents[1];
void APP_Init(void)
{
...
k_work_poll_init(&AppStatus.UTCReadWork, SendUTCToLT);
k_poll_signal_init(&AppStatus.PollSignals.UTCDone);
k_poll_event_init(&UTCEvents[1], K_POLL_TYPE_SIGNAL,K_POLL_MODE_NOTIFY_ONLY,
&AppStatus.PollSignals.UTCDone);
...
}
The following functions modify these structures. App_ScheduleUTCResponse is called from I2C Slave interrupt if the I2C master has requested the UTC time before it is ready. APP_RegisterUTCData is called when a date time event occurs, and it is not of DATE_TIME_NOT_OBTAINED type.
void App_ScheduleUTCResponse(void)
{
int err = k_work_poll_submit(&AppStatus.UTCReadWork, UTCEvents, 1, K_FOREVER);
printk("Poll Submit Error: %d\n", err);
}
void SendUTCToLT(struct k_work *work)
{
FillUTCBuffer(true);
printk("BufferFilled\n");
//k_poll_signal_reset(&AppStatus.PollSignals.UTCDone);
}
void APP_RegisterUTCData(void)
{
int64_t utc;
int err = k_poll_signal_raise(&AppStatus.PollSignals.UTCDone, 0);
printk("Poll Signal Err: %d\n", err);
AppStatus.StateFlags.UTCDataReady = true;
date_time_now(&utc);
utc /= 1000;
CheckGeoDataStale(utc);
time_t rawtime = utc;
struct tm *timesplit;
timesplit = localtime(&rawtime);
printk("Datetime: %s", asctime(timesplit));
}
I see the "Poll Submit Error: 0" message on the UART, and the "Poll Raised Error: 0" message follows the DATE_TIME_OBTAINED_NTP event message. However the work callback function does not get called at all as far as I can tell.
I had a few different configurations before, but they caused system faults of some kind or another. This one doesn't result in any faults, but it doesn't finish the loop. I assume I'm just doing something wrong with the moderately opaque apis, but I have no idea what.
Any help is appreciated!
