Explanation: This line is very important to configure the network, connect Target Server and download debugging procedures.
Default_boot_line is to design without NVRAM's target, so that users do not need to be manually entered manually at each system startup.
XXXendLoad () explains this line when the system starts the network and load it according to the definition of this line.
EMAC (0,0): Start the device, but the device name, such as floppy disk, hard disk, PCMCIA card, etc.
FD is a floppy disk, (0, 0) represents the first floppy drive, 3.5 inch disk. DC indicates starting from the DEC 21x4x chip, that is, the system has NVRAM existence, this way is now not used .lpci indicates the startup device to 3Com Etherlink XL PCI NIC. FEI: Intel 82559 EtherExpress NIC. Nene: NE2000 NIC ELT: 3COM Ethernet Card EEX: Intel NIC ATA: ATA / IDE hard disk .........
405GP: Host Name VxWorks Loaded from Host VxWorks File H = 172.16.1.159 Host IP Address
E = 172.16.254.52 Target machine IP address, if the network starts Target Server, this IP must match the Target IP address configured on the host, and set the back end option for wdbrpcu = xxx username, PW = xxx password: If you load debugged from the network, the username and password of the host's FTP server and the target machine must be the same TN = VXTARGET target name.

#undef sdram_ecc_enable
/ * Interpretation: Here mainly sets the memory allocation definition of the system. If it is assigned, the system does not load and run normally.
ROM_TEXT_ADRS, ROM_SIZE, RAM_HIGH_ADRS, and RAM_LOW_ADRS are defined in config.h and makefile files, and must be consistent, and the definition of these addresses must be made to the VxWorks loading execution process, the hardware manual, MMU, and VxWorks. Main principle It is guaranteed that VxWorks Image has certain running spaces in ROM and RAM and efficiently runs, see VxWorks BSP and startup procedures.

The generation of BSP, download and TARGET Server configuration instance, Pentium host, 3com network card, floppy disk boot, FTP, and FTP, FTP, FTP, FTP, FTP, FTP, FTP, FTP.
1. Modify the BSP file config.h in the C: / Tornado / Target / Config / PCPENTIUM directory. #elif (CPU_VARIANT == Pentium) #define default_boot_line "ELT (0, 0) Host: c: // tornado // target // config // pc PcPENTIUM / / VXWORKS H = 90.0.0.3 E = 90.0.0.50 u = target PW = target tn = target "
#DEFINE INCLUDE_ELT / / 3COM NT #DEfine include_end // END driver
2. Open Tornado Select New Bootable VxWorks Image, select Construction A BSP, select PCPENTIUM, and compile it to generate a vxworks image file in the appropriate directory.
3. Make bootrom; choose Build Boot ROM, select PCPENTIUM, select bootrom_uncmp, generate bootrom_uncmp. Copy BootRom_uncmp to Host / X86-Win32 / BIN, insert the blank disk to the soft area, enter the directory host / x86-win32 / bin in the DOS interface, use the command "mkboot a: bootrom_uncmp" to generate a boot disk
4. In Start> Programs> Tornado2> FTP Server, click the USER / RIGHTS menu under Security, create new users User name: target, password: target, Home Directory for the VxWorks image is located, such as C: / Tornado / Target / Config / PcPentium /. Note These configurations are consistent with config.h.
5. Insert the bootrom's boot disk into the target machine's floppy drive, start the target machine, start from the floppy drive, then log in to the FTP, download the vxworks file from the host, the target machine prompts in 7 seconds, press any key to select Boot mode (manual, automatic), Handmade modifications can be modified for FTP users, passwords, IPs. It is usually waiting for 7 seconds after system autoboot.
