DDR

DDR主时钟修改，开发板133.33MHz，修改相关宏为66.66MHz，采用QCVS重新生成DDR初始化代码，

网络

网络配置，

不从i2c读取MAC #define CONFIG_ID_EEPROM 在* 2080u-boot-qoriq-v2.0includeconfigsT208xRDB.hline652配置千兆网phy地址， #define RGMII_PHY1_ADDR 0x07 /* RealTek RTL8211E */ #define RGMII_PHY2_ADDR 0x06 在*u-boot-qoriq-v2.0archpowerpcincludeasmconfig.hline102，可以看到CONFIG_PHYLIB在这里使能，所以menuconfig没有配置， /* The FMAN driver uses the PHYLIB infrastructure */ #if defined(CONFIG_FMAN_ENET) #define CONFIG_PHYLIB #endif 万兆网走光纤，没有phy，看一下T2080 u-boot的网络初始化过程，用fixed phy驱动取代开发板上的phy。 mac_read_from_eeprom //commonoard_r.c line876 initr_ethaddr //commonoard_r.c line916 initr_net //commonoard_r.c line940 eth_initialize //commonoard_r.c line655 board_eth_init //commonoard_r.c line249 cpu_eth_init //boardfreescale 208xrdbeth_t208xrdb.c line101 fm_standard_init //archpowerpccpumpc8xxxcpu.c line362 fm_eth_initialize //drivers etfminit.c line101 fm_eth_init_mac //drivers etfmeth.c line748 fm_eth_startup //drivers etfmeth.c line771 init_phy //drivers etfmeth.c line775 phy_connect //drivers etfmeth.c line683 phy_find_by_mask //drivers etphyphy.c line856 get_phy_device_by_mask //drivers etphyphy.c line826 search_for_existing_phy //drivers etphyphy.c line710 create_phy_by_mask //drivers etphyphy.c line716 get_phy_id //drivers etphyphy.c line680 phy_device_create //drivers etphyphy.c line683 phy_connect_dev //drivers etphyphy.c line858 phy_reset //drivers etphyphy.c line836 phy_config //drivers etfmeth.c line711 eth_register //drivers etfmeth.c line780 设置环境变量， =>setenv ipaddr <board_ipaddress> =>setenv serverip <tftp_serverip> =>setenv gatewayip <your_gatewayip> =>setenv ethaddr 00:04:9F:03:6B:10 =>setenv eth1addr 00:04:9F:03:6B:11 =>setenv eth2addr 00:04:9F:03:6B:12 =>setenv eth3addr 00:04:9F:03:6B:13 =>setenv eth4addr 00:04:9F:03:6B:14 =>setenv eth5addr 00:04:9F:03:6B:15 =>setenv eth6addr 00:04:9F:03:6B:16 =>setenv eth7addr 00:04:9F:03:6B:17 =>setenv eth8addr 00:04:9F:03:6B:18 =>setenv eth9addr 00:04:9F:03:6B:29 =>setenv ethprime <ethx> =>setenv ethact <ethx> =>setenv netmask 255.255.x.x =>saveenv

Nor Flash

Nor Flash容量扩大，128MB增加到256MB，修改IFC宏，u-boot cp命令没有显示扇区地址，修改源代码添加这个打印。

NAND FLASH

没有Nand，注释T2080RDB.h相关宏，删除LAW，TLB， *oardfreescale 208xrdblaw.c *oardfreescale 208xrdb lb.c

CPLD/FPGA

更改配置头文件T2080RDB.h宏定义， cpu_init_early_f archpowerpccpumpc85xxcpu_init_early.c init_laws archpowerpccpumpc8xxxlaw.c law_table boardfreescale 208xrdblaw.c init_tlbs archpowerpccpumpc85xx lb.c tlb_table boardfreescale 208xrdb lb.c cpu_init_f archpowerpccpumpc85xxcpu_init.c init_early_memctl_regs driversmiscfsl_ifc.c

I2C

取消从EEPROM中读取MAC，取消VID电压控制，

万兆网

万兆网使用光口时，u-boot hwconfig环境变量需要配置， hwconfig = fsl_ddr:ctlr_intlv=cacheline,bank_intlv=cs0_cs1;fsl_fm1_xaui_phy:xfi

设备树

IFC

Nor长度增大，去除nand，增加CPLD长度，

linux内核

menuconfig

打开jffs2，ext4，fuse，net phy，phy subsystem，NVMe，uio，rapidio配置，修改ramdisk，spi-nor配置，

USB

如果没有USB_CLKIN信号，写USB控制寄存器处理器会卡死，如果没有PHY时钟，使用USBx_CONTROL[PHY_CLK_VALID]位来检测USB PHY时钟，此处需要修改内核或者设备树，否则linux会hang住，

CONFIG_DEBUG_SECTION_MISMATCH

待分析， WARNING: modpost: Found 1 section mismatch(es). To see full details build your kernel with: 'make CONFIG_DEBUG_SECTION_MISMATCH=y'

网络

文件*drivers etethernetfreescalesdk_dpaamac.c中获取mac地址，可以在u-boot中设置， /* Get the MAC address */ mac_addr = of_get_mac_address(mac_node); if (unlikely(mac_addr == NULL)) { dev_err(dev, "of_get_mac_address(%s) failed ", mac_node->full_name); _errno = -EINVAL; goto _return_dev_set_drvdata; } memcpy(mac_dev->addr, mac_addr, sizeof(mac_dev->addr));
