CC3000 hangs after failed patching at wlan_start(0) and wlan_start(2)

Hi,

I'm using TMS320C5515 eZdsp as the host MCU and the CC3000 TiWi-SL Rev.2. Pins are connected correctly. I wrote my own SPI, because of lack of control on CS line in hardware SPI delivered with C5515. I'm pretty sure that it works correctly. Before failure at patching I was able to get correct answers on SimpleLink_Init_Start(0), HCI_CMND_READ_BUFFER_SIZE, NVMEM_GET_MAC_ADDRESS and HCI_READ_SP_VERSION, but with an error code 255.

Now my module acts wierd. On SimpleLink_Init_Start(0) it answers with patch request with code 0x02, but no always, sometimes it doesn't send any message. On firmware patch request I answer with Hci_patch_send with length 0 and then the module hangs, no other messages are received. When I try to start module with 0x02(no patch) often it doesn't give any answer, sometimes it's sends packets like 0x00 0x00 0x00..., 0xFF 0xFF 0xFF... or 0x82 0x00 0xFF... .

I'm using patch programmer 1.14. Tried different things, read lot of threads, but found no solution to my problem. Any advice or ideas will be appreciated.

Regards,

Marcin

  The issue causing this problem was not found, but the module was brought back to life with MSP430FR5739 and the newest patch programmer.

  In reply to Marcin Pytel:

  Hi Marcin,
  
  Its good you were able to get the patch on the device, but I really encourage you to move to CC3100 instead. There is a lot more support and functionality for the CC3100.
