Ethernet performance using TSE in uClinux

Hi,

I haven't modified anything to do with that. I'm not sure what you are suggesting -- putting the exception address somewhere other than 0x20? (which on this system is in DDR SDRAM)

Of course, this depends on the MACRO

# if defined(CPU_EXCEPT_ADDRESS_ASM) && (CPU_EXCEPT_ADDRESS_ASM != (LINUX_SDRAM_START + 0x20))

.

If you select the location of exception address in SSRAM with SOPC builder, those scripts automatically set the new address of SSRAM to CPU_EXCEPT_ADDRESS_ASM. So the exception handler is copied to SSRAM. And this is not controlled by linker scripts. If you select the location in DDR SDRAM, it's OK, no problem.

(What do those t's and T's mean?)

Those are 'Symbol Types'. 'T' means that this symbol belongs to 'text' segment and is global.
