hi all can metrowerks's codewarrior complile the u-boot? i want to port the u-boot to my arm lpc2210 in linux , but the board don't give the jtag driver that can write/read flash in linux ,so i want to complile the u-boot in codewarrior and write into flash by jtag in windows

[U-Boot-Users] *.lds for examples
by Robin Getz 08 Oct '04

08 Oct '04

I noticed there was linker files for the examples directory for two architectures (mips and nios), but was struggling to figure out where the default came from. If I have architecture specific examples, do I need to add lds file for the examples? I was trying to add an example, and was unable to get things to work properly. To start I tried just copying the hello_world.c to a smc91111_eeprom.c, and making what I thought were the correct entries in the examples/Makefile and top level Makefile (for make clean only). However, if smc91111_eeprom and hello_world.c are exactly the same, I end up with different object files, because the entry point is different. The following linker error occurs /home/rgetz/uClinux/toolchainoutput/bin/bfin-elf-ld.real: warning: cannot find entry symbol smc91111_eeprom; defaulting to 00001000 So, where is the entry point set? The actual make looked OK to me (sorry for the long lines): bfin-elf-gcc -O0 -ffixed-P5 -D__KERNEL__ -DTEXT_BASE=0x20000000 -I/home/rgetz/u-boot/u-boot_1.1.1/include -fno-built in -ffreestanding -nostdinc -isystem /home/rgetz/uClinux/toolchainoutput/lib/gcc-lib/bfin-elf/3.3.3/include -pipe -D_ _BLACKFIN__ -mno-underscore -DCONFIG_blackfin -D__blackfin__ -I/home/rgetz/u-boot/u-boot_1.1.1 -Wall -Wstrict-prototyp es -c -o hello_world.o hello_world.c bfin-elf-ld -g -Ttext 0x1000 \ -o hello_world -e hello_world hello_world.o libstubs.a \ -L/home/rgetz/uClinux/toolchainoutput/lib/gcc-lib/bfin-elf/3.3.3 -lgcc bfin-elf-objcopy -O srec hello_world hello_world.srec 2>/dev/null bfin-elf-gcc -O0 -ffixed-P5 -D__KERNEL__ -DTEXT_BASE=0x20000000 -I/home/rgetz/u-boot/u-boot_1.1.1/include -fno-built in -ffreestanding -nostdinc -isystem /home/rgetz/uClinux/toolchainoutput/lib/gcc-lib/bfin-elf/3.3.3/include -pipe -D_ _BLACKFIN__ -mno-underscore -DCONFIG_blackfin -D__blackfin__ -I/home/rgetz/u-boot/u-boot_1.1.1 -Wall -Wstrict-prototyp es -c -o smc91111_eeprom.o smc91111_eeprom.c bfin-elf-ld -g -Ttext 0x1000 \ -o smc91111_eeprom -e smc91111_eeprom smc91111_eeprom.o libstubs.a \ -L/home/rgetz/uClinux/toolchainoutput/lib/gcc-lib/bfin-elf/3.3.3 -lgcc bfin-elf-objcopy -O srec smc91111_eeprom smc91111_eeprom.srec 2>/dev/null bfin-elf-objcopy -O binary hello_world hello_world.bin 2>/dev/null bfin-elf-objcopy -O binary smc91111_eeprom smc91111_eeprom.bin 2>/dev/null Any thoughts? pointers appreciated.

[U-Boot-Users] board/board/flash.c
by Bradley Remedios 08 Oct '04

08 Oct '04

Hello All, If we only have Nand flash on our board, does board/ourboard/flash.c really have to be implemented? Shouldn't it be sufficient to just use cmd_nand.c and env_nand.c? For our configuration, U-Boot will actually come up and running from SDRAM itself as we will be using a Primary Bootloader to load U-Boot from Nand Flash. So the only functionality that we should really need is reading and writing to nand flash for writing downloaded images and booting kernels. Regards, -- Bradley Remedios bremedios(a)gmail.com

Hello, I am new to u-boot, but have experience with high-level programming on Linux desktop. But this is my first time to deal with device drivers and flash programming kind of issues. Please forgive my possible naive questions concerning to low level hardware and kernel concepts... We have sandpoint board with mpc8245 CPU. Our goal is to plug-in and run an ethernet card on the PCI bus(specifically Digital DC2114x ethernet, surely it is supported in u-boot). I have been debugging the u-boot for a while, and I concluded that it may be due to interrupt problems(but I may be totally wrong). And when I saw that interrupt routines in cpu/824x/interrupt.c is not implemented yet, I thought that "Yeahh, I found the problem". Then I saw Mr. Denk's following mail, then I confused about the situation. Does u-boot communicate with any hardware on PCI bus without using interrupts. Is this the common way for u-boot (I mean u-boot ports for different architectures, especially comparing with prort for the mpc824x arch.). By the way, I have to say that leds on the ethernet card did never blink under u-boot. (Obviously it is running/blinking on some other Linux PC's). Does it mean something informative (except that it doesn't work)... I am completely stucked at this point. Any kind of help is very appreciated. Thanks in advance... --Eren In message <001201c362f9$aaf09c60$240110ac@jsbae> you wrote: > > i use mpc824x and U-Boot .. > is there someone who used external interrupt to the mpc824x platform?? > how can i setting EPIC for use external interrupt. U-Boot has little (or no) need for interrupts at all. What exactly are you trying to do? Best regards, Wolfgang Denk

hello everyone! As described in u-boot readme file, to run hello_world example we have to write "loads", but this command doesnt seem to work with me and give the following msg Unknown command 'loads' - try 'help' and when i give the command go 40004 Hello World!

[U-Boot-Users] RTL8139 compilation error
by Santoso, Yusdi 07 Oct '04

07 Oct '04

Hi all, I am currently trying to run u-boot on 8241 based board. I am copying my settings from MUSENKI which is also based on 8241. The board has on board Realtek8139 based ethernet port, so I enable CONFIG_RTL8139. But during compilation, the following error occur: rtl8139.c: In function 'rtl8139_probe': rtl8139.c:253: '_IO_BASE' undeclared (first us in the function) ... Basically the out* definitions refused to compile because it is tranlated into _out*( (addr)+_IO_BASE, ... ). So how do you get this _IO_BASE? Should I define it in the "include/config/<board>.h" ? The only other board using RTL8139 is TB0229 but I also can't find _IO_BASE definition anywhere. Thanks, any help is appreciated. Yusdi
