Hello Group,

I was trying to single step the u-boot code from flash on my EP8248 using the Macraigor’s Raven and I noticed that the above instruction generates reset exception at early initiazation phase (first 20 instructions).  It happened right on the first instruction of boot_warm:

Boot_warm:

            Msmsr r5  => exception generated?????

Could you provide some insights/help please?

Thanks,

Nguyen
