Posted on September 28, 2011 at 15:10Hello @ all,
I have acquired a Reva Board with STM32 daughter board ( ftp://www.raisonance.com/pub/Support/RKit-ARM/STM32F107-DB_Schematics.pdf ). Raisonance don't provide some Ethernet examples for their board, so I started to port the LwIP IAP Demo for ST3210C to the Reva board. I must say I am new with this controller and I have no experience with Ethernet PHY's.
There are the steps which I have tried:
- checked the IO's between STM32 and PHY (st3210C uses an other PHY), the IO initialization seems to be correct
- initialized the Ethernet interface in MII mode
- flatten the whole app (no buttons, no ST3210-C Code, just LwIP, printf and http server App)
- used HSE for MCO Clock (25Mhz) to feed the PHY
- used Static IP and DHCP
Running the code brings not the desired result. Y-LED is blinking what means a collision is available but the biggest problem is, I have tried to read the ST100 register, but have got just ''ones''
Here is the main code:
int main(void)
{
int PhyVar, c;
/* Setup STM32 system (clocks, Ethernet, GPIO, NVIC) and STM3210C-EVAL resources */
System_Setup();
USART_Configuration();
GPIO_Blink();
printf(''\r\nSystem initialisiert'');
/* Initilaize the LwIP stack */
LwIP_Init();
/* Initilaize the webserver module */
IAP_httpd_init();
for(c = 0; c < 20; c++) {
PhyVar = ETH_ReadPHYRegister(0x01, c);
printf(''\r\nReg %d: \t %d'', c, PhyVar);
}
/* Infinite loop */
while (1)
{
/* check if any packet received */
if (ETH_GetRxPktSize()!=0)
{
/* process received eth packet */
LwIP_Pkt_Handle();
}
GPIOE->ODR ^= GPIO_Pin_10;
/* Periodic tasks */
System_Periodic_Handle();
}
return 0;
}
Here is the initialization for the Ethernet connection:
