Hi Sir,
I am using AMCC PPC440Gx processor for our project presently the board is
working fine with vxWorks(BSP + OS + Application).
But our customer new requirement is same board should be ported with linux.
1. We are using BDI2000 JTAG tool for porting u-boot and kernel.
2. We are not able to load the u-boot or u-boot.bin file directly to SDRAM
location.
3. When we try to load its load to the flash loaction i.e what ever we mention
in the macro
CONFIG_SYS_TEXT_BASE from board.h file its loads to that location and when
we
give go command it throws an error called JTAG instruction overrun.
4. When we build the u-boot code the file size of u-boot.bin is always created
with the macro
initialized by CONFIG_SYS_TEXT_BASE from the board.h file.
5. We are able to load u-boot.bin to a flash location directly but u-boot is
not coming up.
So to debug the u-boot we are trying to load directly to SDRAM location.
VxWorks is
coming up when we load directly to SDRAM location.
6. I think the u-boot is creating a u-boot.bin file to load for flash loaction.
How to create an
image or bin file to load on SDRAM location directly.
Best Regards,
Sadashiv
