Brief Description of the Problem
1. DK-TM4C123G is working fine with the Tivaware 2.1 quickstart application program.
2. But, when we insert the TIWI-SL CC3000 EV module on the DK-TM4C123G, the display starts continuously resetting on running the CC3000 patcher program.
On debugging the program, system gets reset at the following line
// ASIC 1273 chip enable: toggle WLAN EN line
tSLInformation.WriteWlanPin( WLAN_ENABLE );
(wlan.c line 297)
It is repeatedly displaying following message on hyper terminal
" CC3000 Patch program started"
" Intialising CC3000 WiFi Stack...... Done, "
" Starting.."
Following message on DK-TM4C123G Board's OLED display,
" CC3000 Patcher "
" Connect to Terminal ......"
3. If we remove the TIWI-SL CC3000 EV module, the CC3000 Patcher program waits(but does not reset) after the same messages are displayed only once, on Hyper terminal and OLED.
4. We expect you to guide for locating the problem area, whether the CC3000 Patcher program or the TIWI-SL CC3000 EVM hardware.
Steps to Recreate the Problem
1. Plug in the TIWI-SL CC3000 EVM on DK-TM4C123G Board.
2. Start the CCS 5.4 and hyper terminal on Desktop to read debugger data.
3. Connect the desktop USB cable to DK-TM4C123G Board to Power it on.
4. Run the CC3000 patcher program from the link
C:\ti\TivaWare_C_Series-2.1.0.12573\examples\boards\dk-tm4c123g-em-cc3000
5. Check the response on hyper terminal and OLED messages.
