Hi thanks for your response, I am able to compile the code, but while linking at end ie after -Map u-boot.map -o u-boot I am getting getting follwing errors.

net/libnet.a(net.o)(.text+0x108): In function `ArpRequest': /home/bhagwat/firmware/nuport/bootloader/u-boot/net/net.c:234: undefined reference to `eth_send' net/libnet.a(net.o)(.text+0x24c): In function `NetLoop': /home/bhagwat/firmware/nuport/bootloader/u-boot/net/net.c:306: undefined reference to `eth_halt' net/libnet.a(net.o)(.text+0x280):/home/bhagwat/firmware/nuport/bootloader/u-boot/net/net.c:318: undefined reference to `eth_init' net/libnet.a(net.o)(.text+0x3e8):/home/bhagwat/firmware/nuport/bootloader/u-boot/net/net.c:400: undefined reference to `eth_halt'

I am not getting any pointer to this error, as I have not done any modification in /net folder. Do I need to enable somewhere conditioanl compilation flag. please suggest.

Hi Bhagwat,

This is the basic U-Boot porting process. Start with a reference board if you can, copy files, make adjustments, attempt to compile, and then resolve errors.

Part of the DRAM setup involves defining bank sizes. You need to declare PHYS_SDRAM_1 and PHYS_SDRAM_1_SIZE in your include/config/moschip.h header file. PHYS_SDRAM_1 should be the address of your SDRAM, and PHYS_SDRAM_1_SIZE should be the size.

You will most likely encounter many different errors as you port U-Boot to your board. Examine the error, look at the source, determine what's wrong, and look at other working boards/configurations to figure out what you need to do when required. If all else fails, post an e-mail here!

cheers, Craig

HI all,

I got the U-boot code and I am trying to compile it for my SOC. I am using ARM926EJS core. I have done follwing steps

1. In makefile I have added below lines moschip_config : unconfig @./mkconfig $(@:_config=) arm arm926ejs moschip

2. I have copied header file in include dir $ cp include/configs/armadillo.h include/configs/moschip.h

3. Then I have copied dir $cp board/armadillo/ board/moschip/

after doing $make moschip_config $make

I am getting follwoing errs.. armadillo.c: In function `dram_init': armadillo.c:58: error: `PHYS_SDRAM_1' undeclared (first use in this function) armadillo.c:58: error: (Each undeclared identifier is reported only once armadillo.c:58: error: for each function it appears in.) armadillo.c:59: error: `PHYS_SDRAM_1_SIZE' undeclared (first use in this function) make[1]: *** [armadillo.o] Error 1

Can anyone tell me, If i am missing any steps for compilation.
