Help with host driver port to STM32

Jimmy Pedersen

Other Parts Discussed in Thread: CC3100, CC3100MOD, UNIFLASH, CC31XXEMUBOOST, CC3100BOOST

Hi everyone.

I just started porting the driver for CC3100 to a custom STM32 board.

Looking at my logicanalyser the signals seem correct and I can do basic communication with the CC3100MOD on the board. The problem is that it asserts an error (-7) if I try to do WlanPolicySet (And if I'm not misstaken sl_WlanProfileDel gives the same result).

Anyone have any Ideas what could be wrong?

Also when is code for upgrading the CC3100MOD firmware from my CPU going to be released?
In dire need since the product is already late for release since it has been redesigned from using an CC3000.
(Don't know if it helps but we've already signed your NDA).

Kind regards

Jimmy

UPDATE:

Added delays in CC3100_disable (20 ms) and CC3100_enable(50ms) as suggested in other forum thread.

This didn't help.

I looped my code to ask for the internal clock and had it run at full speed (3900 requests/answers per second) no problem. I had my logicanalyser active at the same time and no interrupts were missed.

What I can see is that I get, what is enterpreted, an event just after calling sl_WlanProfileDel

Also if I enable the debug output of sent/recived bytes the code sometimes continues a bit further (On a few accations all the way to connecting to the network and to the NTP server), this seems to point to a timming problem.

Any Ideas?

Here is my latest debug output:

Hi Jimmy,

-7 error is sFlash error, all of your API involving the sFlash read or write are failing.

You can try formatting the the device and updating the service pack using uniflash. Please refer to uniflash quick start guide for details

http://processors.wiki.ti.com/index.php/CC31xx_%26_CC32xx_UniFlash_Quick_Start_Guide

Updating the service pack from MCU is supported. Please refer to below post for details

http://e2e.ti.com/support/wireless_connectivity/f/968/p/381016/1347739.aspx#1347739

Regards,

Ankur

Hi Ankur1

Thanks for the info.

How is this supposed to work in a production environment where I would need to format all units (1000 units+) flash? Or is this because I have an early module and they will be formatted when I purchase for production later from TI?

A format command issuable from host CPU would be handy.

Kind regards

Jimmy

Hi again

Skipping the clearing of profiles and other flash dependent commands I can now connect to a NTP server on the internet. That great, but now I have to fix the flash problem.

So I'm trying to format the flash on my board.

To learn how this works I first did it with an CC3100BOOST mounted on a CC31XXEMUBOOST and that worked flawlessly.

But when trying the same with a FTDI USB<->serial cable I only get part of the way. It tells me to restart the device and then I get "connection succeeded"after recieving

00 CC

.Ì

unflasher sends

00 03 27 27

..''

I'm then supposed to get something like

00 CC 86

.Ì†

but I'm not.

I only seeing a lot of 0x00 and then some 0x80 packets from the CC3100MOD to uniflasher (That hangs waiting for better answer or something).

What signals are in relevant when flashing? Rx,TX,CTS,RTS and reset oviously. Any other?

I've connected these to the CC31XXEMUBOOST but still no luck (Similar results to when using external USB-Serial converter. IE. I can see that CC3100 sends CC when starting up and UNIFlash sends info for version but gets no reply).

What size of flash is there in the CC3100MOD?

What could I be doing wrong?

Kind regards
Jimmy

Hi Jimmy,

The modules are shipped with pre formatted serial flash (with updated service pack) so you don't need to format them.

Regards,

Ankur

Hi Ankur

This sound very good, is it because I got early modules it's not formatted?

Could you please answer my other questions, in the last post, too, since I still need to fix these modules to continue my evaluation.

Kind regards

Jimmy

Hi Jimmy,

You need RX, TX lines of CC3100 module to work with uniflash. RTS and CTS lines can be tied together.

CC3100 module has 1 MB (8 Mb) serial flash.

Jimmy

is it because I got early modules it's not formatted?

The module you got should be formatted. It looks like the serial flash got corrupted somehow.

Regards,

Ankur

Hi again

I've verified all signals and compared them to the levels of an CC3100boost while programming.

As far as I can see the levels are correct. CS & HIB are both high while programming and nReset only goes low when pressing the button.

I've implemented the same setting on my board (I don't have a reset button so I configure the pins and then do a 50ms low pulse on the CC3100MOD nReset line.

I get the first 0xCC byte and UNIFLASH says connection succeded but then the communications stops waiting for ack after sending get storage list

Are you 100% sure there isn't a difference between the CC3100 chips and the CC3100 module I have(CC3100 ES 1.2.1 I think)?

Kind regards

Jimmy

Ps. Except for the flash not working this module is SO much better than the CC3000. I've got very fast and stable communications with my PC. My next task is to make the module connect to our cloud server and see how that works.

Hi Jimmy,

Can you please share the marking on the CC3100 Module (part no.)?

Any more info?
Suggestions/reasons why the flash isn't/wasn't formated and/or why I still can't format it?
Kind regards
Jimmy

Hi Jimmy,

It looks like you have pre production CC3100MOD samples.
May we contact you at email address you provided in your E2E profile?

Hi Jimmy Pedersen,
I am also trying to port the CC3100 to STM32.
Have you tried the SPI-DMA part ??
