Part Number: CC3100MOD
Tool/software: Linux
Dear Sir/Madam,
I am using CC3100MODR11MAMOBR in my design to interface to beaglebone black board. I am facing issue to get the CC3100MOD to work.
Below is the steps I use to bring up the module but I can't get response from the Module via SPI. Hope you can advise me which part gone wrong.
-> By the way, on my hardware connection, since I am not using hibernate function I had pull it up to 3.3V, is this ok?
1. I had downloaded the SDK from http://www.ti.com/tool/cc3100sdk
2. Download from https://github.cm/rpricken/cc3100-linux. It mentioned it works with CC3100SDK-1.0.0-windows-installer.exe, so I downloaded the CC3100SDK-1.0.0 version.
3. Driver patch
4. SDK Modify Makefile and Build

5. Problem faced
It will hang up at:
|
|
simplelink/source/device.c if (NULL == pInitCallBack) { OSI_RET_OK_CHECK(sl_SyncObjWait(&g_pCB->ObjPool[ObjIdx].SyncObj, SL_O S_WAIT_FOREVER)); /*release Pool Object*/ _SlDrvReleasePoolObj(g_pCB->FunctionParams.AsyncExt.ActionIndex); return _sl_GetStartResponseConvert(AsyncRsp.Status); } |
|
Even I can skip it, but it will hang at sl_WlanSetMode() SPI operation, can't get response from WIFI chip.
Any expert can guide me what is wrong?
Is pull up nHIB is ok when hibernate function is not used?
Best regards,
Kpk
