zcl_attrWrite() is lockup.

When I run zcl_attrWrite(), it is lockup.



zclWriteRec_t *pWriteRec = NULL;
u8 pBuf[2];
pBuf[0] = LO_UINT16(Converted_lux);
pBuf[1] = HI_UINT16(Converted_lux);
pWriteRec->attrID = ZCL_ATTRID_MEASURED_VALUE;
pWriteRec->dataType = ZCL_DATA_TYPE_UINT16;
pWriteRec->attrData = pBuf;
zcl_attrWrite(0x03, ZCL_CLUSTER_MS_ILLUMINANCE_MEASUREMENT, pWriteRec, TRUE);

Your pWriteRec pointer cannot point to NULL.

Your pWriteRec pointer cannot point to NULL.

u8 pBuf[2];
u8 *pData;
pBuf[0] = LO_UINT16(Converted_lux);
pBuf[1] = HI_UINT16(Converted_lux);
memcpy(pData, pBuf, 2);

In this case, memcpy() is lockup.
Why it is lockup ?
