Honored ContributorHi!
I've been testing with different hardware settings, but for the last try I have used the standard 1c20 Altera example (altera/kits/nios2/examples/vhdl/niosII_cyclone_1c20/standard/standard) leaving only the cpu, ram, flash, timer and jtag_uart. I open the ptf with the nios2configtool, and change the text, rodata and rwdata regions to ext_ram. I also uncheck "Work with a ROM monitor". I also set the startup type to ROMRAM Then, I start the eCos kernel building, and the eCos tests building. It works OK. In order to test the tests, I have created a new custom project, and copied the elf executable test files to my project tree. Then I configure the project with the ptf of the evaluation board, and I try to run it with the ISS emulator, and the result is: " Info : Successfully read SOPC Builder PTF file 'C:\altera\NIOS2_Projects\NIOSII_standard\std_1c20.ptf' Info : The SOPC Builder system contains the following modules: Info : Bus module 'cpu_instruction_master_bus' - avalon.dll Info : Bus module 'cpu_data_master_bus' - avalon.dll Info : Master module 'cpu' - altera_nios2.dll Info : Slave module 'ext_flash' - altera_avalon_flash.dll Info : Address span: 0x0000-0x7FFFFF (cpu_instruction_master_bus) Info : Address span: 0x0000-0x7FFFFF (cpu_data_master_bus) Info : Slave module 'ext_ram' - altera_memory.dll Info : Address span: 0x800000-0x8FFFFF (cpu_instruction_master_bus) Info : Address span: 0x800000-0x8FFFFF (cpu_data_master_bus) Info : Slave module 'sys_clk_timer' - altera_avalon_timer.dll Info : Address span: 0x920800-0x92081F (cpu_data_master_bus) Info : Slave module 'jtag_uart' - altera_avalon_jtag_uart.dll Info : Address span: 0x920820-0x920827 (cpu_data_master_bus) Warning : SOPC Builder system component reconfig_request_pio is not supported by the simulator.

Also notice that when we run it in the board, it also hangs, and the debug does not respond. The fact is that other tests work, but I think this test should also work, as it checks the stability of the system. If you know any thing I can try... Thanx Alex
