This CPU card is based on an i.MX23 CPU. The card is shipped with:
|
|
|
|
|
|
|
|
- 32 MiB synchronous dynamic RAM (mobile DDR type)
|
|
|
|
- ENC28j60 based network (over SPI)
|
|

|
|
|
Memory layout when @b barebox is running:
|
|
|
|
|
|
|
|
- 0x40000000 start of SDRAM
|
|
|
|
- 0x40000100 start of kernel's boot parameters
|
|
|
|
- below malloc area: stack area
|

@section get_imx23evk_binary How to get the bootloader binary image:
|
|
|
|
|
|
|
|
Using the default configuration:
|
|
|
|
|
|
|
|
@verbatim
|
|
|
|
make ARCH=arm imx23evk_defconfig
|
|
|
|
@endverbatim
|
|
|
|
|
|
|
|
Build the bootloader binary image:
|
|
|
|
|
|
|
|
@verbatim
|
|
|
|
make ARCH=arm CROSS_COMPILE=armv5compiler
|
|
|
|
@endverbatim
|
|
|
|
|
|
|
|
@note replace the armv5compiler with your ARM v5 cross compiler.
