BOOSTXL-CC3120MOD: STM32L152RE

Part Number: BOOSTXL-CC3120MOD
Other Parts Discussed in Thread: CC3120MOD, CC3120

I have to implement WIFI communication with the host microcontroller STM32L152RE and CC3120MOD chip.

I try to use "simplelink_sdk_wifi_plugin_2_30_0010" and Keil compiler to do that.

I created a project according to my hardware with STM32CubeMX for Keil compiler and moved all folders with files from "simplelink_sdk_wifi_plugin_2_30_0010" to Keil project.

I reach a stage when the compiling go through well, but on linking stage there are a lot of problems.

Mostly on driver.c file. A lot of undefined Semafor symbols and functions and more.

I'm not so smart with drivers software.

As far as understand the main problem is to combine software and hardware.

Maybe with somebody I can to solve these problems step by step.

Thanks.

Hi,

Please see chapter 16 in www.ti.com/.../swru455, it illustrates what all you need to be done.

Thanks,
I have read swru455 and work with it..
Problem is that cc_pal.h in "simplelink_sdk_wifi_plugin_2_30_0010" has includes:

#include <ti/drivers/dpl/SemaphoreP.h>
#include <ti/drivers/dpl/MutexP.h>
#include <ti/drivers/dpl/ClockP.h>
#include <time.h>

"simplelink_sdk_wifi_plugin_2_30_0010" does not have folder /dpl with these files.
I found out that this folder there is in "simplelink_msp432p4_sdk" to see semaphore/mutex examples, but seems to
me they are too much hardware dependet to be ported easily.
I want non-OS environmet I not define SL_PLATFORM_MULTI_THREADED but compiler ask about semaphore/mutex funcitons any way.
It will be good if sombody tell full set files necessary for build project.

Thanks..

I have problems with SPI port for communicating with CC3120.

SPI_CLK = 1MHz

I am trying to get a response from CC3120 to my Host STM32L152.

I have ported SPI to my MCU and SPI works fine.

I go throug funciton from driver.c

static _SlReturnVal_t _SlDrvRxHdrRead(_u8 *pBuf, _u8 *pAlignSize)

{

.....

NWP_IF_WRITE_CHECK(g_pCB->FD, (_u8 *)&g_H2NCnysPattern.Short, SYNC_PATTERN_LEN);

......

NWP_IF_READ_CHECK(g_pCB->FD, &pBuf[0], 8);

}

I always read in pBuf zeros..

On Logic Analyzer on MOSI I see sending the pattern to CC3120 on MISO signal really constantly 0.

Strange that IRQ signal just repeats signal nHIB.

When nHIB goes high IRQ goes high when nHIB goes low IRQ goes low..

IRQ signal never changes in between sending and receiving pattern.

Even I receive a lot of bytes from CC3120 (always zeroes) IRQ never goes low...

Might need to send some special message to CC3210?

Might be there is some simple program to test SPI port to communicate with CC3120?

Thanks.

Hi,

Unfortunately I am not able help with this issue. I haven't experiences with this issue. Please wait for answer from TI engineers.

Thanks Jan

Just one more issue.

When using UART I see some data come in to host immediately after set nHIB high, but from SPI I don't see any data when I read data after set nHIB signal to high..

Will wait for an answer.

Thanks.

Hi,

Do you see the correct sync pattern being sent to the CC3120? Do the rest of your SPI signals look like the diagram shown in the SPI host interface guide?
processors.wiki.ti.com/.../CC3100_SPI_Host_Interface
I would also double-check the SPI configuration that you have against the config table and ensure that it is correct.

Regards,
Michael

Thank you so much Michael..

I'll try again according to SPI_Host_Interface.
