+# Pelion Device Management Client example for Mbed OS
+
+This is clone of https://github.com/ARMmbed/mbed-os-example-pelion and focuses on Nuvoton targets.
+
+## Support targets
+
+Platform                        |  Connectivity     | Storage for credentials and FW candidate  | Notes
+--------------------------------|-------------------|-------------------------------------------|---------------
+Nuvoton NUMAKER_PFM_NUC472      | Ethernet          | NU SD card                                |
+Nuvoton NUMAKER_PFM_M487        | Ethernet          | NU SD card                                |
+Nuvoton NUMAKER_IOT_M487        | Wi-Fi ESP8266     | NU SD card                                |                              |
+Nuvoton NUMAKER_IOT_M263A       | Wi-Fi ESP8266     | NU SD card                                |
+Nuvoton NU_PFM_M2351_NPSA_NS    | Wi-Fi ESP8266     | NU SD card                                |
+
+**Note1**: M2351 is not supported on Mbed Online Compiler. Use Mbed CLI instead. Besides, its support is limited to specific version (7bfbb8e70559), not the latest version.
+This is because Mbed OS [doesn't support Armv8M secure code build since 6.0.0-beta-1](https://github.com/ARMmbed/mbed-os/pull/12737).
+
+## Known issues
+
+-   Meet error with `fcc_init() failed with 1`
+
+    ```
+    The device has not provisioned yet. Try to provision it...
+    Provision for development...
+    Reset kvstore...
+    Reset kvstore...OK
+    Provision for development...OK
+    Application ready
+    Connect to network
+    Network initialized, connected with IP 192.168.8.101
+
+    Start developer flow
+    fcc_init() failed with 1
+    ```
+
+    When the error happens, it is possibly caused by [incorrect check with non-default configuration of FLASHIAP](https://github.com/ARMmbed/mbed-os/pull/12808).
+    Mbed OS 5.15.2, 5.15.3, 6.0.0 alpha, and 6.0.0 beta all suffer from this.
+    Use Mbed OS 5.15.1 instead to avoid this error.
