Hi everybody My name is Martin and I'm new to this mailing list. I hope this is the right place to ask my question. I'd like to install U-Boot on a Karo TX25. From the Denx FTP server I've downloaded the 2011.12 release of U-Boot and compiled it using the arm-linux-gnueabi-gcc (4.4.5) from Debian: $ make tx25_config $ CROSS_COMPILE=arm-linux-gnueabi- make all After compiling I've downloaded the u-boot.bin file to the board using the pre-installed RedBoot: RedBoot> load -r -b 0x80100000 -h 192.168.1.101 u-boot.bin Using default protocol (TFTP) Raw file loaded 0x80100000-0x80129617, assumed entry at 0x80100000 Finally I tried to start U-Boot directly from RAM: RedBoot> exec Using base address 0x80100000 and length 0x00029618 After that, the board (or at least the serial connection) stops working. I also tried the same with the pre-compiled binaries from here: http://www.denx-cs.de/sites/all/files/tx25.zip but with the same result.
May someone can explain me, how to download U-Boot to the Karo TX25 using the already installed RedBoot and execute it directly? Is this even possible? My final target is to replace RedBoot with U-Boot, so I'd like to write U-Boot to flash in a second step. Does I've to use the u-boot-nand.bin file instead of u-boot.bin for this? Thanks!
