cc3100 mac address

Hi Ankur

From some reason the call to sl_NetCfgGet above returns -2001, although the value in macAddressVal seems to bevalid. According to the doc it should return zero on success. I am working with 3100, SDK 5.2.

Hi Michael,

I am able to reproduce the issue. I will check further on this and update here.

Hi Michael,

The Error -2001 is received when the RX buffer is less then the received data.

While getting the MAC address the network processor sends the 8 bytes but the request was for 6 bytes (size of MAC) and the result is trimmed to 6 bytes.

For this particular case the return value of -2001 can be ignored.

Hi Ankur,

So there is no issue. Understood.

Thanks,

Michael

Is there a plan to fix this?  Or maybe adjust the value of SL_MAC_ADDR_LEN from 6 to 8 so the return value when requesting SL_MAC_ADDR_LEN bytes returns "success"?

This code...

long slResult;
unsigned char macAddr[SL_MAC_ADDR_LEN];
unsigned char macAddrLen = SL_MAC_ADDR_LEN;

slResult = sl_NetCfgGet(SL_MAC_ADDRESS_GET, NULL, &macAddrLen, macAddr);

/* slResult is incorrectly -2001 */

... is much more natural (and correct, IMHO) than this code...

long slResult;
unsigned char macAddr[SL_MAC_ADDR_LEN + 2];     /* crazy bug */
unsigned char macAddrLen = SL_MAC_ADDR_LEN + 2;

slResult = sl_NetCfgGet(SL_MAC_ADDRESS_GET, NULL, &macAddrLen, macAddr);

/* slResult is now correctly 0 */

Hi Chris,

This bug will be fixed in next release of the SDK.
As you have mentioned you can either use 8 byte buffer (SL_MAC_ADDR_LEN + 2) and pass macAddrLen as 8 bytes or you can ignore the error value of -2001.

HI
I try to get the MAC , but when the code run to sl_NetCfgGet() func,its not comeback ,
I add the linking of all functions (sl_NetCfgGet -> VERIFY_RET_OK(_SlDrvCmdOp((_SlCmdCtrl_t *)&_SlNetCfgGetCmdCtrl, &Msg, &CmdExt)); -> _SlDrvObjLockWaitForever(&g_pCB->GlobalLockObj); -> OSI_RET_OK_CHECK(sl_LockObjLock(pLockObj, SL_OS_WAIT_FOREVER)) -> _SlNonOsMainLoopTask(); )

Hi,

I have a same problem like Harel. Program fail on call VERIFY_RET_OK(_SlDrvCmdOp((_SlCmdCtrl_t *)&_SlNetCfgGetCmdCtrl, &Msg, &CmdExt));. I realised that problem start with call _SlDrvCmdOp(). Any answer?

Thanks

Hello,

I was about to ask this same question and I see an answer: "Yes, all the shipped bards have a unique MAC address."

I just want to ask for clarity.  Are you saying that only "boards" come with a MAC address (like the EVMs) or do the raw chips themselves come pre-flashed/etched with an address?  If I were to order 1000 bare chips, am I going to need to apply for an address range for our company?  If every chip has a unique address already, is it read only so that someone couldn't accidentally wreck it during development?

Thanks!

Michael

I had the same problem,
rebuild project fixed it for me
