UDP引导加载程序更改IP

您想在运行时更改地址吗？然后你必须重写一些代码…添加一些变量等。



      以下为原文

    You want to change the Address at runtime? Then you must rewrite some of the code... add some variables etc.

假设您正在使用MHC和谐调度器，您可以在其中设置IP地址配置，它将调整您的代码。这条线（看起来你已经改变了它）是什么设置IP地址。你可能需要给我们一点关于你要做的事情的信息。



      以下为原文

    Assuming you are using the MHC Harmony confgurator,  you can set the IP address configuration there and it will adjust your code.    This line ( it looks like you've changed it anyway ) is what sets the IP address.  you might need to give us a little more info on what you are trying to do.



 
#define TCPIP_NETWORK_DEFAULT_IP_ADDRESS "192.168.26.199"

嗨，我已经在Flash中存储了IP，我可以读它并写它。我想在读Flash和在“TCPIPSISTACKIGIN（）”之前打开我的配置板的IP。我试着创建一个结构来替换具有const值的结构，但是我找不到办法去做它。My IpCon无花果被储存在这样的结构里。谢谢你。



      以下为原文

    Hi,
I've stored the IP in flash, I can read it and write it.
I would like to change the IP of the board at startup just after read my config in flash and before the "TCPIP_STACK_Init()".
I've tried to create a structure to replace the one with the const value but I don't find the way to do it.
My IpConfig is stored in a structure like this.
 
typedef struct __attribute__ ((packed))
{
    IPV4_ADDR IP_Address;
    IPV4_ADDR IP_Mask;
    IPV4_ADDR DEFAULT_GATEWAY;
    IPV4_ADDR PRIMARY_DNS;
    IPV4_ADDR SECONDARY_DNS;
    //TCPIP_MAC_ADDR MAC_Address;
        
    uint16_t SERVER_PORT_MVT;
    uint16_t SERVER_PORT_HOST;
    uint16_t SERVER_PORT_DBG;
    uint16_t SERVER_PORT_SPV;
    
}IP_CONFIG;
 
Thanks you

好的，我找到了解决办法，它很完美，希望对别人有所帮助。



      以下为原文

    Ok I've found the solution
            IPV4_ADDR IP = EEPROM_Data.IpConfig.IP_Address;
            TCPIP_STACK_NetAddressSet(netH, (IPV4_ADDR *)&IP, (IPV4_ADDR *)&Mask, true);
 
And it works perfectly
 
Hope it will help someone

所以我会这样开始：



      以下为原文

    So I would start like this:
 
#define TCPIP_NETWORK_DEFAULT_IP_ADDRESS EEPROM_Data.IpConfig.IP_Address

But I can see you've already done it better :) so ok!

我不能回答我自己，所以对你来说，DarioG又一次。



      以下为原文

    I can't make answer to myself so it is for you DarioG once again
 

好吧，下一个最好的（我以前做过了，也许你也做过了）



      以下为原文

    Ok
the next best one (I did it in the past and possibly you did it too) is
strcpy (EEPROM_Data.IpConfig.IP_Address,TCPIP_NETWORK_DEFAULT_IP_ADDRESS);
at boot when the EEprom is blank, and then use the EEprom data as you show.

对不起，我再次尝试初始化配置后，但它不工作，我尝试过这一点，当我试图这样读回来，但我总是得到0.0.000 0.000 0.000。我真的需要初始化TecCPIPHooStx配置。真的需要帮助达里奥：



      以下为原文

    Sorry back again I've tried to set the config after the initialization but it doesn't works
I've tried this
    EEPROM_Data.IpConfig.IP_Address.Val = 0x301AA864;//192.168.026.100
    EEPROM_Data.IpConfig.IP_Mask.Val = 0x10FFFFFF;//255.255.255.000
    EEPROM_Data.IpConfig.DEFAULT_GATEWAY.Val = 0xFB1AA8C0;//192.168.026.254
    EEPROM_Data.IpConfig.PRIMARY_DNS.Val = 0xFB1AA8C0;//192.168.026.254
    EEPROM_Data.IpConfig.SECONDARY_DNS.Val = 0;

TCPIP_NET_HANDLE netH;
    IPV4_ADDR IP = EEPROM_Data.IpConfig.IP_Address;
    IPV4_ADDR Mask = EEPROM_Data.IpConfig.IP_Mask;
    TCPIP_STACK_NetAddressSet(netH, (IPV4_ADDR *)&IP, (IPV4_ADDR *)&Mask, true);
            
    IP = EEPROM_Data.IpConfig.DEFAULT_GATEWAY; TCPIP_STACK_NetAddressGatewaySet(netH,(IPV4_ADDR *)&IP);
    IP = EEPROM_Data.IpConfig.PRIMARY_DNS; TCPIP_STACK_NetAddressDnsPrimarySet(netH,(IPV4_ADDR *)&IP);
    IP = EEPROM_Data.IpConfig.SECONDARY_DNS; TCPIP_STACK_NetAddressDnsSecondSet(netH,(IPV4_ADDR *)&IP);
and when I tried to read them back like this
    IPV4_ADDR ipAddr;
    TCPIP_NET_HANDLE netH;
    const char *netName, *netBiosName;
    
    netH = TCPIP_STACK_IndexToNet(0);
    ipAddr.Val = TCPIP_STACK_NetAddress(netH);
    sprintf(buffChar1,"rnIP : %03d.%03d.%03d.%03d",ipAddr.v[0],ipAddr.v[1],ipAddr.v[2],ipAddr.v[3]);SendDebugBuffer(buffChar1,22);
    
// ipAddr.Val = TCPIP_STACK_NetMask(netH);
// ipAddr.Val = TCPIP_STACK_NetAddressGateway(netH);
// ipAddr.Val = TCPIP_STACK_NetAddressDnsPrimary(netH);
// ipAddr.Val = TCPIP_STACK_NetAddressDnsSecond(netH);
 
 
But I always get 000.000.000.000 .
I really need to initialize the TCPIP_HOSTS_CONFIGURATION .
Really need help DarioG  :)
