[U-Boot-Users] mfmsr r5 generates exception

[Nguyen Nguyen]

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
