I am trying to use the Nimble examples for the Esp32S3 and the Esp32C3.

I am trying both the "ble_spp" and "bleprph" examples.

Both examples fail on this line:

Code: Select all

nimble_port_init();

The error is:

assert failed: os_msys_init_once os_msys_init.c:56 (rc == 0)

I believe this failing here :

Code: Select all

void
os_msys_init(void)
{
    os_msys_reset();

    (void)os_msys_init_once;
#if MYNEWT_VAL(MSYS_1_BLOCK_COUNT) > 0
    os_msys_init_once(os_msys_init_1_data,
                      &os_msys_init_1_mempool,
                      &os_msys_init_1_mbuf_pool,
                      MYNEWT_VAL(MSYS_1_BLOCK_COUNT),
                      SYSINIT_MSYS_1_MEMBLOCK_SIZE,
                      "msys_1");
#endif

#if MYNEWT_VAL(MSYS_2_BLOCK_COUNT) > 0
    os_msys_init_once(os_msys_init_2_data,
                      &os_msys_init_2_mempool,
                      &os_msys_init_2_mbuf_pool,
                      MYNEWT_VAL(MSYS_2_BLOCK_COUNT),
                      SYSINIT_MSYS_2_MEMBLOCK_SIZE,
                      "msys_2");
#endif
}

Has anyone seen this? Is there a workaround or something I am setting up incorrecly fo the Nimble port on these chips?

Thanks!

I don't have a solution I'm afraid, but I have the same problem. Have you filed a bug on the esp-idf repo?

Hi @jeremy , @FreyaRose,

It looks like initial memory pool init itself has failed. Can you share some more information:
1. Which IDF branch you observing this issue on ?
2. Are there any other changes done with respect to configuration? If possible, please share your sdkconfig.

Thanks

Also came across this issue in nimble example.

Hi !

I faced the same problem and was able to solve it by calling

Code: Select all

esp_nimble_hci_and_controller_init()

before

Code: Select all

nimble_port_init()

for esp-idf-4.4 as explained here : https://docs.espressif.com/projects/esp ... g-sequence

Hope that helps !
