Hi Light King (is this a calory reduced monarch?) ;)
I m newly using U-Boot in a customised platform of processor Intel xscale PXA255.
U-Boot 1.1.6 (Jul 28 2008 - 10:01:53) is running in this board . In this board one external 64 mb RAM is there and one 64 mb flash is there .
RAM address is starting from 0xA0000000 . Flash address is starting from 0x00000000 .
I m compiling the U-Boot source with arm-linux-gcc toolchain 3.4.1 .
then I m transfering the hello_world.bin image to the board through serial . If I downloading this image to any RAM address and executing from there by go command then board is rebooting . If I m trying to download to 0x40000 adress ( given by the U-Boot document ) and trying to execute from that adddress then it is giving some garbage output . plz help me about this
The standalone application needs to be linked to a static address. If you look into the Makefile in examples, you'll see that for your board "LOAD_ADDR = 0xc100000", i.e. that's where the binary _can_ run. If this is not RAM on your system, adjust the makefile, rebuild the app, load it at that address and then run from there. retry.
