[U-Boot-Users] Uboot version querry
by Ajay Jain 01 Aug '06

Hi, We are porting uboot to an ARM based proprietary board (MM6+). I was looking at the version available on the ftp site. It has the latest version "u-boot-2006-06-30-2020.tar.bz2", whereas the latest version that sourceforge talks about is "U-Boot 1.1.4". Which is the recommended stable version, to begin the port. I could not find this information anywhere on the uboot official site. Another querry, other than the "README", is there any other document availabe that talks about porting uboot on new ARM board? Thanks, Ajay

Hi, I am doing the following commands: make mrproper OK make at91rm9200dk_config OK make u-boot and I=B4ve got the following error message: ... -Map u-boot.map -o u-boot arm-linux-ld: ERROR: = /usr/local/arm/3.4.1/lib/gcc/arm-linux/3.4.1/libgcc.a(_divsi3.oS) uses = hardware FP, whereas u-boot uses software FP The "cpu/arm920t/config.mk" file has the "-msoft-float" option set, but = the arm-linux-gcc seems to be compiling everything for a hardware FP. Does someone had this problem before?=20 Regards, Carlos

HI: I use a 8MB TOP FLASH, with CFI driver can not handle this type, becasue SECT info order is for BOTTOM FLASH, so I modefied for it.
