I suppose that at least it breaks at all other timer init... Anyway you can place also a breakpoint at jtag uart init and see if it stops also there.

Just a hint: I see a watchdog, did you disabled it when you debug your device? Because if for example you reset your device if it not refreshed correctly, probably your debugging is fake.

Anyway initialization of device is required.

As a last option, you could call ALTERA_AVALON_EPCS_FLASH_CONTROLLER_INSTANCE and ALTERA_AVALON_EPCS_FLASH_CONTROLLER_INIT within your main()... :cry:

Ciao

Yes I disabled it.

I did so, an you see the result in attachment... it stops, but not at the bp. Strange!?

What is ALTERA_AVALON_EPCS_FLASH_CONTROLLER_INSTANCE? I've never read it.
