tiwi-sl initialization blocks

The received data after SpiReadHeader is

0x81 0x81 0x00 0x00 0x00 0x03 0x82 0x00 0x08 0x01

Any ideas?

Hi Alexander,

Integrity, the company i'm working for already integrate the CC3000 on NXP (LPC4300) and STM32f0-discovery board.

With all the issues we had, we never encounter a situation where the SPI read was invalid. 

The connection we had was long lines, so we had to lower the SPI clock into 1MHz (What clock are you using?)

Also, if you have a scope, can you please send me the first command and the following lines? (MOSI, CLK, MISO, Chip select and IRQ?)

We have a lot of experience looking at scope and finding the issue.

I'm glad to hear that!

As far as I remember the clock phase influence on both output/input commands. So the CC3000 should have ignore the first command (since the clock is out of phase). Does ST have different settings? Or the clock phase changed at the beginning of the read transaction?

Thank you,

- Elad

Dear Elad ,

I have the same problem   

wlan_start(0) function call is blocking on 

SimpleLinkWaitEvent(HCI_CMND_SIMPLE_LINK_START, 0);

(within SimpleLink_Init_Start)

Do you have some suggestion to check where is wrong?

THANKS

Hi,

Could you tell us what is the SPI state, was the wlan interrupt triggered?

Dear Elad ,

How should I set clock phase (CPHA) and CPOL on the host controller(MSP430)??

Edward

Hi Chia,

MSP430 is already integrated to the MSP430, please look MSP430 CC3000 project, and look at "basic_wifi_application" function "init_spi"

You will find the exact SPI configuration

- Elad

Dear Elad,

I use basic_wifi_application" function,but it shut down at SimpleLinkWaitEvent.

IRQ CS PWREN Vcc Gnd SIMO SOMI CLK pin have already been set.

I don't know where is wrong.

Hi Edward,

Are you also using  stm32 controller as described in the begining of this thread?
If so, can you plese send a logic capture of the SPI lines?
If not, please open a new post and describe the HW setup that you are using and what are the settings you have for SPI, IRQ, CS and clocks.

Thanks,
Alon.S

I am using lpc cortex mo microcontroller i have also face this problem . I need solution

The received data after SpiReadHeader is

0x81 0x00 0x7F 0x00 0x00 0x03 0x81 0x00 0x00 0x00

Hi Alexader khaustov ,

                   how do you solve this problem . i am also have this problem that is why i am asking you.

                  Thanks.

I've marked the solution that worked for me as verified answer. I'm unsure as regards the Elad's question
