Can't display an image after rtc sleep

[rotemb-hailo]

Hi, I was wondering, do you have an example with actual rtc sleep? Because its seems like I can't draw an image after rtc sleep.

What am I missing?

#include "EPD_5in65f.h"
#include "EPD_Test.h"
#include "image1.h"
#include "image2.h"

static void print_datetime_t(datetime_t* t)
{
    printf("Sleep callback - %d/%d/%d %d:%d:%d \n", t->day, t->month, t->year, t->hour, t->min, t->sec);
}

static void sleep_callback(void)
{
    datetime_t t;
    rtc_get_datetime(&t);
    print_datetime_t(&t);
}

static void set_time(void)
{
    // Start on Friday 5th of June 2020 15:45:00
    datetime_t t = {
        .year = 2020,
        .month = 06,
        .day = 05,
        .dotw = 5, // 0 is Sunday, so 5 is Friday
        .hour = 15,
        .min = 45,
        .sec = 00};

    // Start the RTC
    rtc_set_datetime(&t);
}

static void rtc_sleep2(int min)
{

   datetime_t t_alarm = {
        .year = 2020,
        .month = 06,
        .day = 05,
        .dotw = 5, // 0 is Sunday, so 5 is Friday
        .hour = 15,
        .min = min,
        .sec = 00};

    // uart_default_tx_wait_blocking();
    sleep_goto_sleep_until(&t_alarm, &sleep_callback);
}

int EPD_5in65f_test(void)
{
    printf("EPD_5in65F_test Demo\r\n");
    if (DEV_Module_Init() != 0)
    {
        return -1;
    }

    printf("e-Paper Init and Clear...\r\n");
    EPD_5IN65F_Init();
    EPD_5IN65F_Clear(EPD_5IN65F_WHITE);
    DEV_Delay_ms(100);

    rtc_init();
    EPD_5IN65F_Display(Image1);
    DEV_Delay_ms(4000);
    EPD_5IN65F_Sleep();
    DEV_Delay_ms(1000);
    set_time();
    rtc_sleep2(46);

    EPD_5IN65F_Init();
    DEV_Delay_ms(1000);
    EPD_5IN65F_Display(Image2);
    DEV_Delay_ms(4000);
    rtc_sleep2(47);

    printf("e-Paper Clear...\r\n");
    EPD_5IN65F_Clear(EPD_5IN65F_WHITE);
    DEV_Delay_ms(1000);
    EPD_5IN65F_Sleep();

    // close 5V
    printf("close 5V, Module enters 0 power consumption ...\r\n");
    DEV_Module_Exit();

    return 0;
}

The code seems to be stuck every run, in a different place, around this lines: https://github.com/waveshareteam/Pico_ePaper_Code/blob/main/c/lib/e-Paper/EPD_5in65f.c#L171
