Re: [U-Boot] working with loadb & bootm on u-boot-v2 for imx27ads Board
Hi All, I am successfully able to get the U-boot prompt on my board based on IMX27ads. However I am facing the following issue. Please help me out : I want to load the Linux Kernel Zimage on to RAM. As per the documentation we have used the following command to load zImage using Kermit protocol. " U-boot-v2> loadb -c zImage " (Also tried " U-boot-v2> loadb -f zImage ") Which successfully downloads zimage to the file with default offset set as 0x. a) But I am not able to understand to which location in RAM this image is written to? b) Please let me know how exactly to load kernel image to specific location on RAM? c) Also how we can change the default location since the user is not given an option to mention the address. d) How to load the file " zImage" to RAM? I was intending to do the following steps : >> loadb 0x10 zimage >> loadb 0x100 ramdisk.gz >> bootm 0x10 0x100 Please help me out as I am using U-boot-V2 for the first time. I am attaching the loadb.c file which I am using currently. Are there any patches Waiting for your responses.

But nothing helps. The image being tried is getting loaded on the same board when board is flashed with redboot using the following commands. 1) load -r -b 0x10 -m xmodem zimage 2) load -v -r -b 0x0100 -m xmodem ramdisk.gz 3) exec -r 0x00100 -s 0x0060 -b 0x10 -l 0x0020 -c "init=/linuxrc console=ttymxc0,115200 root=/dev/ram" If any suggestions, please share..!!

I am using gcc-4.1.2-glibc-2.5-nptl-3 cross compiler toolchain to build uboot.bin and uImage. We are using the below procedures to build uImage from linux souce. 1.

We are trying to boot kernel using bootm command but the kernel got stuck in starting kernel memory location. Please find the logfile attachment. We are laoding uImage on target using the following commands. 1. loadb -f /dev/ram0 -o 0x100 uImage 2. bootm /dev/ram0 Please suggest me where i am going wrong. It will be a great help.
