We are developing a PXA 27x based board and trying to boot WInCE 5.0 on
it.
The board has an ethernet controller and our plan has been to use the
standard eboot code available from Plarform builder. However we are facing
some hardware issues due to which the ethernet controller is not
accessible.
To save time, we are thinking of flashing the Kernel image ( NK.bin)
directly
to flash using JTAG. There are some issues here for which any help would
be
greatly appreciated:
1. How to create a Kernel Image as a .nb0 file, that can be directly
flashed
over JTAG?
The easiest way is probably to use cvrtbin and viewbin tools (in
\WINCE500\PUBLIC\COMMON\OAK\BIN\I386) : you can have a look at ¨B help on
this
2. If the eboot code is modified, can this kernel image be copied to SDRAM
and jump the execution point to KernelStart routine?
Your eboot simply has to jump at the beginning of the image (nk.nb0).
3. Is it possible to execute the image out of Flash itself ( we are using
asynchrnous NOR flash )?
XIP is possible. You often only have to change addresses (NK region) in
config.bib so that is becomes the address of the flash where your image will
be burned.
