Wi-Fi Combo Forum Discussions

I have a board which has an ST microprocessor and BCM Wiced module. The ST Micro uses ST Link for debug. I followed the thread

SN8000 WiFi Module with STM Discovery Board in my attempt to get STLink working. I know the OCD (V4) delivered with Wiced needs the configuration stlink.cfg to work so I grabbed the config file from the standard distribution of OCD to make it work.

My command is "snip.gpio-BCM943362WCD4-debug JTAG=stlink-v2 download"

I keep getting an error:

I'm working with Wiced 3.1.2 and trying to connect to the board but I keep getting:

Downloading Bootloader ...

I've also experimented with a couple of variants of the config files to get it working with no changes.

Any ideas?

Hi, Broadcom Support team

Can you give me an example of RSA relative functions? For instance:

rsa_init, rsa_free, rsa_public, rsa_private ......

Thanks,

Where I can download these files "WICED™ Evaluation Board User Guide  Number: WICED-EUM2xx-R "  from  Page 6 of WICED  Development System Quick Start Guide__MMPWICED-QSG203-R.pdf ?  My evaluation board is WICED BCM943362WCD4. Thanks.

Hi

This was reason of one of my problem , and I have mentioned this in another thread but didn't got a valid reply, so re-posting again.

When I use debug / run along with the build string for compiling and downloading a sample application causes the WiFi throughput to be very low.

How I measured this was when I used udp_transmit app

snip.udp_transmit-SN8000x-FreeRTOS-LwIP-debug download ,

I observed that the UDP packet creation+sending takes 8 milliseconds (same with download run also), But when I changed the build string to

snip.udp_transmit-SN8000x-FreeRTOS-LwIP download

The UDP packet creation+sending takes only about 400 microseconds.

This indicates a severe performance degradation while using debug or run in the build string.

What causes this behavior ?

Does anybody at broadcom have a schematic of using the LPC17xx with the  BCM943362. There is example code in the wiced\platform\mcu folder from which I could derive the connections but I thought I would ask before going down that path.

Along similar lines has anybody used the SDIO interface on the bigger LPC devices such as the 43xx to connect to a BCM943362.

Hello Guys,

I have HTTP server. Some of my webcontent files are quite large 50-150KB. When I build for NetX_Duo, HTTP file requests are completed successfully. However, when I build for LWIP files get truncated when they get to the client, thus webcontent does not get properly displayed in the browser. Also none of the following HTTP requests are responded by the server.  I am working with WICED 3.1.2. LWIP works ok with small files.

There have been a discussion : http://community.broadcom.com/message/9742#9742

But it does not seem to have been resolved.

Basically, I have noticed that LWIP fails to transfer large files in response to HTTP requests. I cannot figure out the size threshold yet.

Any ideas, how to resolve this limitation?

Many thanks.
