K64F Ethernet cannot connect in tickless mode

janjongboom commented 5 years ago

Description

Mbed OS 5.11.4 (ecb3c8c837162c73537bd0f3592c6e2a42994045), K64F, develop profile, GCC ARM 6. Running Pelion Device Management Client.

When enabling tickless mode on K64F it can no longer connect to Ethernet.

int main() {
    NetworkInterface *net = NetworkInterface::get_default_instance();
    nsapi_error_t net_status = NSAPI_ERROR_NO_CONNECTION;
    while ((net_status = net->connect()) != NSAPI_ERROR_OK) {
        printf("Unable to connect to network (%d). Retrying...\n", net_status);
    }

Throws 'Unable to connect to network (-3015).'

If you wrap the call to connect with sleep_manager_lock_deep_sleep(); and the corresponding unlock call connection works fine.

@janjongboom I finally got a chance to look into this. First I tested the latest mbed-cloud-client-example and the latest mbed OS code. I was able to pass all these: (1) gcc_arm develop tickless off (2) gcc_arm develop tickless on (3) gcc_arm debug tickless off (4) gcc_arm debug tickless on (5) arm develop tickless off (6) arm develop tickless on

I tried to revert to the 5.11.4 mbed-os release, but the latest mbed-cloud-client-example no longer builds with this release.

This issue is not reproduce-able with the latest code.

I'll be closing this issue. If you can still reproduce this issue with the latest release, please either reopen it or create a new issue.
