printf does not display in the console

Thanks for feedback.

mcr42 i am using a jtag_uart from SOPC builder.

Cris, i debugeed as you suggested, when i break at alt_main() the debugger starts running and deosnt actually allow for me to step into any code, it displays an error stating

remote communication error: software caused connection abort.

If i break at program entry point it runs to a thread at location 0x0000000000. If i step into the next instruction i get the following error:

cannot find bounds of current function.

I have attached a screenshot of my debug panel.

even when tested individually neither the code to driver the leds or the printf work.

hmmmmmmmmmm
