Re: ecos for ATLAS (MIPS 4Kc)

In the ecos configtool I chose Atlas 4Kc Template & just modified the Start-up Type to RAM (ROM is the default). If I build it I get the following errors:

Is RAM start-up supported for Atlas 4Kc boards? Or did I miss somethings here?

I don't know exactly why this is happening but those missing functions are only meant to be defined in ROM startup. Somehow vectors.S is including the hal/mips/atlas/current/include/platform.inc file with CYG_HAL_STARTUP_ROM defined. That should never happen. Have a look at the install/include/pkgconf/hal.h file and see what it actually says, or try to work out why it thinks it's defined.
