teConfigCacheWrite

int32 teConfigCacheWrite(
    uint32 handle,
    char* file,
    uint16 reserved
);

Parameters

handle

Handle to the device.
file

Path of a *.htf file to write the configuration cache data to. If NULL, the
configuration cache data is written to the connected device.
reserved

Currently unused, should be set to 0.

Return Values

-1 = Invalid handle
0 = Error
1 = Success
2 = Unsupported function

Remarks

This function is used to write configuration data from the cache.

The teConfigCache* functions are unsupported for BlueCore and CSRC9xxx ICs
(for BlueCore ICs use the ps* functions).

Example

static const char* const CFG_DB_PARAM = "hyd.sdb:CSRA68100_CONFIG";
        static const uint32 KEY_READ_BUFFER_LEN = 128;

        cout << "Trying to connect..." << endl;
        uint32 teHandle = openTestEngine(TRB, "1", 0, 5000, 0);

        if (teHandle != TE_INVALID_HANDLE_VALUE)
        {
            cout << "Connected!" << endl;

            // Initialise the configuration cache
            int32 teRet = teConfigCacheInit(teHandle, CFG_DB_PARAM);

            // Read the configuration into the cache from the device
            uint16 unused = 0;
            if (teRet == TE_OK)
            {
                teRet = teConfigCacheRead(teHandle, NULL, unused);
            }

            // Read current XTAL trim value
            if (teRet == TE_OK)
            {
                char valueString[KEY_READ_BUFFER_LEN];
                uint32 maxLen = KEY_READ_BUFFER_LEN;

                teRet = teConfigCacheReadItem(teHandle, "curator:XtalFreqTrim", valueString, &maxLen);
                if (teRet == TE_OK)
                {
                    cout << "curator:XtalFreqTrim = " << valueString << endl;
                }
            }

            // Write updated XTAL trim value
            if (teRet == TE_OK)
            {
                teRet = teConfigCacheWriteItem(teHandle, "curator15:XtalFreqTrim", "3");
            }

            // Write Bluetooth address
            if (teRet == TE_OK)
            {
                teRet = teConfigCacheWriteItem(teHandle, "bt15:PSKEY_BDADDR", "{0x3456,0x5B,0x02}");
            }

            // Write the configuration cache to the device
            if (teRet == TE_OK)
            {
                teRet = teConfigCacheWrite(teHandle, NULL, unused);
            }

            closeTestEngine(teHandle);
        }
