cc3100 nxp lpc1769

Hi Otto,

Can you please share few more details?
1. Is your application able to initialize the networking sub system (sl_Start() function call)?
2. Are you running the application in debug mode? If yes can you please share the exact location where the application is getting stuck?
3. Did you try running the examples ported on LPC1769 with CC3100 BP.

Regards,
Ankur

Hi Ankur,

thank you for your quick reply,

This is a screenshot with debugger, serial console and Website:

The application never leaves sl_Start().

I Don't have connected my bp Hardware to my lpc1769 board yet.

Thanks

Otto Parzhuber

Hi Otto,

I will suggest you to first test the ported solution on CC3100 BP + LPC board.
It can also be a porting issue. Please make sure you are following the guidelines for the porting the solution on other platform. processors.wiki.ti.com/.../CC31xx_Host_Interface

Ankur

Hi Ankur,

i have tested my LPC-Board on CC3100 BP and I could successfully run the examples in the sdk examples folder.

This is the output of the serial console after running the program on my CC3100 hardware. I have included outputs on spi read and spi write

Do you have an advice what could be wrong?

Thank you

Otto

Hi Otto,

The interface communication between CC3100 and NXP looks to be fine but the application is failing. Can you please check and share the error return value by host driver function.

Regards,
Ankur

Hi Ankur,

thnak you for your help. Following is an output of my console with returns of the device driver.

In your Docs I have found the corresponding enum for the sl_Start return value:

ROLE_AP_ERR (Failure to load MAC/PHY in AP role)

Until now i haven't found any hardware error in my design.

Thank you

Otto

Hi Ankur,

meanhwile I have measured a few voltages during start up of the program. I have measured strange voltages VDD_PA, VDD_PLL, VDD_RAM, DIG_CC, PA_SWP, PA_SWN and VDD_ANA. The VDD (3V3) has got constantly 3V3 with a small ripple.

Probably its a hardware issue, but i don't know whats wrong on my design.

Thank you

Hi Otto,

I am not able to see the images in above post.

I have few question:
How are you powering your board? How much current can be sourced by supply?
Did you formatted and updated the service pack on the device using uniflash?

Regards,
Ankur

Hi Ankur
I have included a pdf now....Your answer was too fast.

I didn't format and update the service pack...but I think its a hardware failure.

Updated pdf with all relevant voltages:5428.CC3100 Fehlerprot_oszi.pdf

The two oscillators are working.

Thank you
Otto

Otto,

Every new device + serial flash need's to be formatted and the service pack should be updated. This is required for the device to create its file system on the serial flash.
This may be the cause of the above behaviour.

Also please share the current rating for the CC3100 power source on your board.

Regards,
Ankur

Hi Ankur,

meanwhile I have formatted the serial flash and have updated the device with a new servicepack.

For testing I have connected the cc3100 board to a 5A powersupply. The board draws about 60 mA, measured with a simple multimeter.

The result is the same as described in my last post.

I have inluded 3 PDF Files:

1) The measured voltages8875.CC3100 Fehlerprot_oszi.pdfCC3100BoardPhotos.pdfCC3100.PDF

2) Schematic and PCB

3) Photos of the Board.

The main difference to the reference design are a few not included 100nF blocking Cs. (Components are placed on Top- and BottomLayer, SignalLayer1 is GND and SignalLayer2 is connected to the different Voltages (3V3, VDD_DIG_CC, VDD_PA and so on).The UART interface I have temporary connected with isolated wire to a ftdi chip.

Thank you

Otto

Hi Ankur,
can you tell me which of the voltages are depending on VDD_ANA?
Thank you
Otto

Thank you Ankur,

meanwhile I have designed a new Board with nearly the same placement of components and same routing as your refernece design.

When the board is assembled I will tell you the result.

Regards

Otto

Hi Otto,

Thanks for the update.
I am closing this thread, for follow up queries please open a new thread and a link to this one for reference.

Ankur
