These are the steps to get U-Boot booting from SD Card: These are the steps to get U-Boot booting from SD Card:
$ git clone https://github.com/yuq/u-boot-sunxi.git 1. Get the U-Boot sources for the pcDuino
$ cd u-boot-sunxi
$ make pcduino CROSS_COMPILE=arm-none-eabi- $ git clone https://github.com/yuq/u-boot-sunxi.git
$ sudo dd if=./spl/sunxi-spl.bin of=/dev/sdb bs=1024 seek=8
$ sudo dd if=nuttx.bin of=/dev/sdb bs=1024 seek=32 2. Build U-Boot. We really only want the SPL program; this builds
the whole thing:
$ cd u-boot-sunxi
$ make pcduino CROSS_COMPILE=arm-none-eabi-
NOTES:
a. You may need to use a different tool prefix for the CROSS_COMPILE=
value, depending upon what toolchain you have installed and upon
which platform your are working.
b. When I try this on Cygwin, I get a make failure that is, apparently,
due to some script incompatibility.
3. Insert a FLASH stick. Use dmesg to get the name of the new USB
device. Make sure that it is not mounted, then (assuming that the
USB device is /dev/sdb):
$ sudo dd if=./spl/sunxi-spl.bin of=/dev/sdb bs=1024 seek=8
$ sudo dd if=nuttx.bin of=/dev/sdb bs=1024 seek=32
