BOOSTXL-CC3135: ported cc3135 driver freezes at sl_start()

Bas van den Berg69

Part Number: BOOSTXL-CC3135
Other Parts Discussed in Thread: UNIFLASH, CC3135

I am trying to port the SimpleLink driver to a MCU from nordic. I have the code ready, but the code freeze at sl_start() in the function:

VERIFY_RET_OK(_SlDrvWaitForInternalAsyncEvent(ObjIdx,
INIT_COMPLETE_TIMEOUT,
SL_OPCODE_DEVICE_INITCOMPLETE));

I think the code is waiting on an interrupt at the IRQ pin.

I have measured the different pins, and I’ve noticed the IRQ pin stays low.

I see the nHIB pin toggle on sl_DeviceDisable() and sl_DeviceEnable().

I have also measured the IRQ pin when the board isn't connected to a host.

in this situation I pressed the nHIB button to see if IRQ changes, but the IRQ pin stays low.

The CC3135 if flashed with uniflash with use of this guide: http://dev.ti.com/tirex/content/simplelink_academy_msp432sdk_2_40_00_17/modules/wifi/wifi_imagecreator/wifi_imagecreator.html

can someone help me with this problem?

Bas van den Berg69,

Can you confirm you are sending commands over SPI to the CC3135?

Hi Vincent,

There are no commands send over SPI. The spi_Write function is not executed.

the code hangs after an device disable and enable function.

Bas,

This sounds like a issue with the SPI driver on your nordic device.

I would reach out to there support for more support.

Hi Vincent,

The SPI is initialized but there is no call to a function to send something over the SPI in SL_Start().
There is no interrupt generated because the IRQ pin is constantly low.
If I manually use the SPI functions it works like it should do.

Kind regards,

Bas

Bas,

Is this on a custom board or are you using launchpads?

Hi vince,

i have done the measurment on a CC3135 Boosterpack

kind regards,

Bas,

Can you provide a pinout of everything you are connecting to the device? The issue is either in how you are connecting the devices together or the port of the driver.

Vince

Hi Vince, sorry for the delayed response.

I've noticed the board was asking a current of 700 mA. So I have ordered a new development board. On this board I see the IRQ interrupt I haven't seen on the first board.

after the Interrupt the Nordic MCU sends {0x65, 0x87, 0x78, 0x56}. The only thing i receive are Zero's. Do you know what is going wrong. The delay between the nHIB pulse and IRQ toggle is ~10ms.

Kind regards,

Bas

Hi Vince,

The IRQ pin was set to trigger on falling edge instead of rising edge. everything is working fine now.

Thank you for your help.

Kind regards,

Bas
