I have added OpenOCD flash algorithm of our company's MCU, and i confirmed target identification (probe) of MCU as reading ID register of device.

I have also confirme d to control (write or read ) data from peripheral registers is enabled, but writing or erasing code to flash memory, it is always failed.

it takes a much time about 78 seconds (0.098KiB/s) while 7KB binary code (bootloader) is writing to flash memory.

Although Adapter speed is replaced 1MHz (up to 3 MHz) from 100khz to connect JTAG, what is the reason that the speed of writing to flash memory is too slow?

Hi All,

I am trying to send a rather large packet over TCP in AP mode. The packet varies anywhere between 1400 to 1800 bytes. When I give this length to "wiced_packet_create_tcp", it sometimes returns the "available_space" parameter with a value smaller than my packet size.

What does this mean? Does it mean I have to split up my packet or is it dependent on any other memory?

Has my application occupied so much memory that the TCP stack is unable to find any more memory?

I am using WICED 3.3.1 with (FreeRTOS + LwIP) on an MXCHIP EMW3162 module with STM32 and BCM43362A2.

Sample Code: (Function from my end responsible for sending packets).

    if ((result = wiced_packet_create_tcp( socket, strlen (response), &tx_packet, (uint8_t**) &tx_data, &available_data_length )) != WICED_SUCCESS )

    {

        MYLOG("TCP packet creation failed, %d", result);

        return WICED_ERROR;

    }

    if (available_data_length >= strlen(response)) {

        MYLOG (" Not enough memory available for sending data ");

        return WICED_ERROR;

    }

Thanks in advance for the help.

Best Regards,

Hi,

I am using Murata SN8205, SDK V3.1.2.

Issue 1 -

We see that sometimes the device hangs on wiced_wifi_scan_networks(). The device can hang anytime and is very difficult to debug.

Is there any known issue between the communication between the STM32F2 MCU and the BCM43362?

The default interface is WWD SDIO, does the SDIO driver have any know issue? Is it advisable to use WWD SPI interface?

The device does not need high bandwidth transmission.

Issue 2 -

When we are in an environment with around 50-150 Access Point(AP), again we see that the wiced_wifi_scan_networks() hangs.

What is the expected behavior of WWD when encountering >100 Access points?

Is there any patch for these hang issues?

Environment:

Kit: BCM9WCD9EVAL1_5

Module: BCM943364WCD1_2

SDK: 3.4.0 and 3,5,2

OS: window 7 (64bit)

Hello, is there anyone who tested Appliance example in SDK version 3.4.0 or 3.5.2??

I want to develop demo app with Appliance example, but when I finished downloading Appliance demo on the board, It doesn't work at all.

It doesn't show any logs.

By the way, other example is working well. (Temp_control demo)

(+ I changed make target name with download_apps, and I attached each build log)

demo.appliance-BCM943364WCD1 download_apps run

demo.temp_control-BCM943364WCD1 download_apps run

Is there any way to run appliance demo ?

Regards,
