rm57l843 移植lwip的问题

Hi Lian,

您好！您可以参考我们Hercules wiki上关于LWIP的例程和说明：

http://processors.wiki.ti.com/index.php/HALCoGen_Ethernet_Driver_and_lwIP_Integration_Demonstration 

For TMS570LC43x and RM57x devices:

1. Under the ‘Driver Enable’ tab, enable EMAC Driver and SCI1 Driver.
2. Under ‘VIM RAM’ add the names of the ISRs for EMAC Transmit and Receive Interrupts (Channels 77 and 79 respectively).
3. Enable these interrupts under the ‘VIM Channel 64-95’ tab.
4. Under the ‘PLL’ tab, change the multiplier for both PLLs to a value of 150, such that the output frequency in both cases is 300.00 MHz.
5. Under the ‘GCM’ tab, change the value of the VCLK1, VCLK2 and VCLK3 Dividers to 1 and VCLKA4 Divider to 2, such that the output of VCLKA4_DIV is 37.50 MHz.
6. Under the ‘PINMUX’ tab, enable RMII/MII, under Pin Muxing. Under Input Muxing, enable MDIO(G3), MII_COL(F3), MII_CRS(B4), MII_RX_DV(B11), MII_RX_ER(N19), MII_RXCLK(K19), MII_RXD[0], MII_RXD[1], MII_RXD[2], MII_RXD[3], MII_TX_CLK.
7. Under the ‘EMAC’ tab, change the EMAC address to the correct address (the default one in the example is mentioned above). The physical address is 1 by default.
8. Generate the system initialization and HAL Code.

以上8点，我都尝试过了，但现在仍然不能网络连通。

因为给的例子程序是CCS的程序，而我们目前的程序都是IAR下的工程，我们是用HAL Code Gen生成IAR的驱动，然后再上面移植OS和LWIP，

移植的OS和LWIP在RM48上已经试过了，都没问题，我们这边估计是驱动的问题。

对比了例程的驱动和我们用HAL Code Gen生成IAR的驱动，发现有很大的不同。而且例子的CCS工程，在我们的板子上也可以跑通，网络可以连通。

请问，是否用HAL Code Gen生成的CCS和IAR的驱动，区别非常大，是否有可能是生成的IAR驱动，有问题？
