Hi Jerry!
Please find attached a binary file with a memory dump (address 0x0000--0x3fff) of our CPCI-405 board (PPC405GP based). I initialized the memory with 0xaa and then started U-Boot. You can see, which memory locations are written (with exception vector code) from U-Boot.
Hope this helps...
Best regards, Stefan.
If someone out there has a 405GP running with u-boot, I'd really appreciated a snapshot of the interrupt vector table. It appears that though the vector and and the int return vector are getting copied, however if prior to running u-boot I zero out all memory in the IVT, I see that not Prologue code etc is getting coping into those ares.
If I look at "trap_init" it appears as though it does not copy code, and only sets vectors.
If I look at "relocate_code" it appears as though it only starts to copy code from the top of the boot rom to the end. I do not see where the interrupt vectors are stored in the bootrom - although they must - so I must be missing a simple calculation someplace -
Any assistance is greatly appreciated.
Jerry Walden
