I'm trying to build a server using STM32F207 processor and LAN8742A I have used CubeIDE to generate the configuration code as follows:
1) ETH -> Auto negotiation Enabled
-> PHY Address = 0
-> PHY SR Offset = 1F
-> PHY Speed Mask = 0x0004
-> PHY Duplex Mask = 0x0010
-> PHY Interrupt Source Flag register Offset = 0x001D
-> PHY Link Down Interrupt = 0x0010
Rest of the settings are default. Since I found these to be wrongly auto generated.
2) LWIP -> LWIP_DHCP = Disabled
-> IP Address = 192.168.001.111
-> Netmask Address = 255.255.255.000
-> Gateway Address = 192.168.001.001
3) LWIP -> Key Options -> MEM_SIZE (Heap Memory Size) = 10*1024 Bytes
Then generated the code and added the below
int main(void)
{
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
MX_LWIP_Init();
while (1)
{
MX_LWIP_Process();
}
}
But unable to ping the above IP address from my command prompt. when i check "Ipconfig" on the command prompt, it shows this
Autoconfiguration IPv4 Address. . : 169.254.89.23
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . :
I have cross verified it shows the above only when I connect LAN cable to my board. But doesn't show my IP Address which I configured.
The Processor is able to communicate with PHY , I could check on my Oscilloscope, the data sent is correct via MDIO and MDC. If I can establish this ping, then I have to create a TCP Server using my board to transfer sensor data to pc and receive command from PC.
Please Help me through , what am I doing wrong or if there are any bugs in the STM32 libraries etc.
