how to read JN5169 userdata?

[benoit_roue]

Hello,

According to JN-UG-3099, we can write MAC address, AES key and userdata in an OTP area of the JN5169.

3 x 128 bits words are reserved for user data. That is said, now how the application firmware can read these words?

Best regards

Benoit

Hi, 

These are attached in the zip and should be copied into the Componenets\HardwareAPI\Include Folder of your SDK.

Reads back the MAC address. Passing TRUE in bReadCustomerMACID causes the customer MAC address to be read, otherwise, the default MAC address is read.

PUBLIC bool_t bAHI_ReadMACID(

           bool_t   bReadCustomerMACID,

           uint64  *pu64CustomerMACId);‍‍‍‍‍‍‍‍‍‍

Reads back the security key.

PUBLIC bool_t bAHI_ReadUserData(

           uint8    u8UserFieldIndex,

           uint32   au32userData[4]);‍‍‍‍‍‍‍‍‍‍

Reads back user data.

PUBLIC bool_t bAHI_ReadUserData(

           uint8    u8UserFieldIndex,

           uint32   au32userData[4]);‍‍‍‍‍‍‍‍‍‍

Hope it helps.

Regards,

Mario

Hi Mario,

Thank you for your fast reply. In the mentioned community post, they only talk about the MAC address.

However, my question is about the 3 words of userdata, here is how to write it in the chip:

Once these date are written, how read them from the application firmware?

Hi Benoit,

File zps_apl_aib.h

typedef struct
{
    uint32 u32OutgoingFrameCounter;
    uint16 u16ExtAddrLkup;
    uint8  au8LinkKey[ZPS_SEC_KEY_LENGTH];
} ZPS_tsAplApsKeyDescriptorEntry;

Hi Mario,

Since this function is doing a search by using a IEEE address, it doesn't tell me how to use it for reading raw data from the userdata.

Is there a particular way to write the userdata first?

Best regards

[mario_castaneda]

Hi Benoit,

You can find your own address in the next struct  MAC_ExtAddr_s; mac_sap_CombineMac.h.

Please look at the https://www.nxp.com/docs/en/user-guide/JN-RM-2013.pdf

typedef tuAES_Block AESSW_Block_u;

Regards,

Mario
