I run memory test inside u-boot. It seemed to work fine the first 30
seconds. I left it running for a while and when came back to the
terminal, u-boot quit back to kermit. Connect command did not work
after. And also, after that for some reason my serial-USB connector on
/dev/ttyUSB0 disappeared and /dev/ttyUSB1 appeared. So, I had to
re-connect with ttyUSB1.

I have two System.map files and only one of them has "__log_buf". Why
is u-boot/'s version missing it?
petalinux-dist/u-boot/System.map
linux-2.6-x-petalogix/System.map <- "__log_buf" is at address 0x901b3df8

When I md this address right after u-boot upload (without kernel
start), I see Linux version 2.6.20, PetaLinux build, CPU info, etc.

If I upload kernel, however, using xmd as described in my previous
post, the "klimit" message is displayed and u-boot becomes
inaccessible. Did you want me to check this address after kernel
loading attempt by any chance?

With regards to dcache and icache I haven't enabled them yet. Could
this be a problem?

Thanks,
Victor
