ok

no - only for performance

ok

> Any other ideas?

yes. I have some. :-) you have some choices.
The first and I think the best is compared your .config file with any noMMU
config file in vendor folder. Look at FTL, memory allocator and others

The second make config_menuconfig and use ROMFS instead of cramfs. Just for test.

The third - look at romfs folder to etc/inittab - I hope you see line with
agetty /dev/ttyS0 your baud rate. FYI: in latest svn petalinux repo uartlite use
different name ttyULx. In case you use latest distr and older kernel - you will
have difference between them.

The fourth - you can turn on manually heartbeat function -
arch/microblaze/kernel/heartbeat.c - just remove if there and change BASEADDR to
your GPIO output in case you have it. Tristate mode is not supported there.

Michal Simek
