using Mongoose OS, I have a function mgos_ethernet_init, defined in app2\deps\ethernet\src\esp32\esp32_eth.c If this function returns false the device fails to boot. I am attempting to create a retry for this function and to allow boot to continue if it fails, after setting a fail flag.

Apparently this isn't a global variable?

I created this file:

#include "mgos.h"
#include "mgos_eth.h"

static int retry_count = 0;
static const int MAX_RETRIES = 2;
static const int RETRY_DELAY_MS = 500; // 5 seconds retry delay

static void retry_ethernet_init_cb(void *arg) {
    if (!mgos_ethernet_init()) {
        retry_count++;
        if (retry_count < MAX_RETRIES) {
            LOG(LL_INFO, ("Retrying Ethernet initialization attempt %d/%d.", retry_count + 1, MAX_RETRIES));
            mgos_set_timer(RETRY_DELAY_MS, 0, retry_ethernet_init_cb, NULL);
        } else {
            LOG(LL_ERROR, ("Ethernet initialization failed after %d attempts.", MAX_RETRIES));
            // Handle failure, perhaps set a flag or proceed with other initializations
        }
    } else {
        LOG(LL_INFO, ("Ethernet initialized after retry."));
        retry_count = 0;
    }
}

bool mgos_deps_init(void) {
    if (!mgos_ethernet_init() && retry_count == 0) {
        LOG(LL_INFO, ("First Ethernet initialization failed, setting up retry."));
        mgos_set_timer(RETRY_DELAY_MS, 0, retry_ethernet_init_cb, NULL);
    }
    // Continue with other dependency initializations
    return true; // Return true to continue boot regardless of Ethernet status
}

in app2\src\custom_init.c

although mgos_ethernet_init is not defined, as shown in this compile error:

/c/mos/app2/src/custom_init.c: In function 'retry_ethernet_init_cb':
