How to porting u-boot to my own board?

Hi Scott,

I am in trouble now.

1. My u-boot flash driver

You said I can use flash.c. So, I browse flash.c(include /common/flash.c). I found AMDLV065D.c just have both parts of two flash.c files. So, I think I can change AMDLV065D.c to my use.

I change CFG_MAX_FLASH_SECT and CFG_MAX_FLASH_BANKS(in board.h), change flash_id = FLASH_MAN_AMD + FLASH_AMDL323B. Is it right?

2. In order to Programming U-Boot into Flash, I add 1M sram.

But, when do as USING.TXT, it appears

Communication port must be specified.

Use openport <port> to configure the communication port

cd d:/My_Project/MtxCyclone_uBoot/BootLoader/u-boot-src/u-boot

1> halt

Communication has not been established with remote unit.

2> load bin 0x00600000 u-boot.bin

Why?

3. I use NIOS_IDE Flash Programmer to download u-boot to my flash. After that I run # nios2-terminal

Nothing happen, I do know why?

Thanks,

LiangYi
