Hey,
I get the following errors when running my application and I am not sure how to debug this (The nrf thread viewer is empty when I start a debug session of my application).
The error started to occur, when I introduced a k_work item to offload the translation of received uart data as well as a K_MSGQ to communicate said data to my main loop. For uart I used 'uart_callback_set' to receive uart events.
The situation is something like the following:
sensor.h:
struct location_data {
int64_t unix_time_ms;
double longitude;
double latitude;
int source_mode;
};
extern struct k_msgq gnss_message_queue;
sensor.c:
K_MSGQ_DEFINE(gnss_message_queue, sizeof(struct location_data), 4, 1);
static uint8_t rx_buf[600];
struct uart_work_data {
struct k_work work;
uint8_t *buffer;
size_t data_len;
} w_data;
void work_function(char* c, size_t data_len){
struct location_data data;
translate_msg(c, data_len, &data);
k_msgq_put(&gnss_message_queue, &data, K_MSEC(50));
}
static void uart_work_handler(struct k_work *item) {
struct uart_work_data *work_data = CONTAINER_OF(item, struct uart_work_data, work);
work_function(work_data->buffer, work_data->data_len);
}
static void uart_cb(const struct device *dev, struct uart_event *evt, void *user_data)
{
switch (evt->type) {
case UART_RX_RDY:
uint8_t buffer[600];
size_t buffer_size = sizeof(buffer);
size_t data_len = evt->data.rx.len;
size_t offset = evt->data.rx.offset;
memcpy(buffer, &evt->data.rx.buf[offset], data_len);
w_data.buffer = buffer;
w_data.data_len = data_len;
k_work_submit(&w_data.work);
break;
case UART_RX_DISABLED:
uart_rx_enable(dev, rx_buf, sizeof(rx_buf), SYS_FOREVER_US);
break;
}
}and the main.c:
#include "sensor.h"
int main(void){
k_work_init(&w_data.work, uart_work_handler);
struct location_data data;
while(1) {
if(k_msgq_get(&gnss_message_queue, &data, K_MSEC(50)))
return;
do_something(data);
}
}Any help would be appreciated
