Hi,

We are using WICED-WIFI BCM943362WCD4.

We are trying to write data onto serial flash available in evaluation board.

We tried using example code snip.spi_flash_read.

We could read data but not able write any data onto memory using wiced_spi_transfer() calls.

We could read the value of serial flash status register by entering the command 0x05h and it is giving right value(default 0x1E).

we tried to modify the value of serial flash status register  to 0x02 by giving command  0x01, data  0x02.

But after writing, when we try to read the register, it gives the value 0x00.

Are we missing anything.?

Does wiced_spi_transfer API takes care of enabling and disabling of CE of serial flash?

Thanks

Could you please explain what does thread execution state TX_TCP_IP (12) mean?

There is no description about it in ThreadX documentation.

Thanks,

Johan

Hi!

I'm running a TCP server on Wiced AP interface and there are some issues with that when wanting to have multiple of sockets at the same time. I'm using ThreadX NetX-Duo.

Wiced has a wrapper API for TCP socket listen that defaults to the STA interface:

wiced_result_t wiced_tcp_listen( wiced_tcp_socket_t* socket, uint16_t port );

This has to be modified if you want to use the AP interface. Please add a new API or add interface parameter to the existing one.

Please consider adding:

wiced_result_t wiced_tcp_listen_ap( wiced_tcp_socket_t* socket, uint16_t port );

wiced_result_t wiced_tcp_listen_ap( wiced_tcp_socket_t* socket, uint16_t port )

{

    tcp_listen_callback_t listen_callback = NULL;

    struct NX_TCP_LISTEN_STRUCT* listen_ptr;

    WICED_LINK_CHECK( socket->socket.nx_tcp_socket_ip_ptr );

    /* Check if there is already another socket listening on the port */

    listen_ptr = IP_HANDLE(WICED_AP_INTERFACE).nx_ip_tcp_active_listen_requests;

    if ( listen_ptr != NULL )

    {

        /* Search the active listen requests for this port. */

        do

        {

            /* Determine if there is another listen request for the same port. */

            if ( listen_ptr->nx_tcp_listen_port == port )

            {

                /* Do a re-listen instead of a listen */

                if ( nx_tcp_server_socket_relisten( socket->socket.nx_tcp_socket_ip_ptr, port, &socket->socket ) == NX_SUCCESS )

                {

                    return WICED_SUCCESS;

                }

                else

                {

                    return WICED_ERROR;

                }

            }

            listen_ptr = listen_ptr->nx_tcp_listen_next;

        } while ( listen_ptr != IP_HANDLE(WICED_AP_INTERFACE).nx_ip_tcp_active_listen_requests);

    }

    /* Check if this socket has an asynchronous connect callback */

    if (socket->callbacks[WICED_TCP_CONNECT_CALLBACK_INDEX] != NULL)

    {

        listen_callback = internal_tcp_listen_callback;

    }

    if (socket->socket.nx_tcp_socket_state != NX_TCP_CLOSED)

    {

        nx_tcp_server_socket_unaccept( &socket->socket );

        if ( nx_tcp_server_socket_relisten( socket->socket.nx_tcp_socket_ip_ptr, socket->socket.nx_tcp_socket_port, &socket->socket ) == NX_SUCCESS )

        {

            return WICED_SUCCESS;

        }

        else

        {

            return WICED_ERROR;

        }

    }

    else

    {

        if ( nx_tcp_server_socket_listen( socket->socket.nx_tcp_socket_ip_ptr, port, &socket->socket, WICED_DEFAULT_TCP_LISTEN_QUEUE_SIZE, listen_callback ) == NX_SUCCESS )

        {

            return WICED_SUCCESS;

        }

        else

        {

            return WICED_ERROR;

        }

    }

}

I want to download image to STM32  F205RG internal flash(1MB).

I assign the address of app boot dct download to flash and reset. the console only have a log (Starting Wiced v2.4.1)

                    start address

Boot ： 0x08000000 (waf_bootloader-NoOS-NoNS-BCM943362WCD4-SDIO.bin )

DCT1： 0x08004000 (DCT.bin )

DCT2： 0x08008000 (DCT.bin )

APP :   0x0800C000 （demo_appliance-BCM943362WCD4-FreeRTOS-LwIP.bin ）

Is this right? how to assign address?

I took much time to find the download link and failed to download.

Can we give a note on the top of forum?

Thanks,

Hank
