SSRAM Verify failed after adding custom components in SOPC Builder

I created a system based on the template for the Stratix II Nios Kit. I took the SDRAM away since I don't have a license for that IP Core. I intended to use SSRAM since it's a small project. I compiled in quartus and programmed the FPGA then created a hello world application in Nios IDE and it compiled and run ok. Now when I add custom components in SOPC Builder like PWM and ADC interface, generate, assign pins, compile in quartus, and try to compile in Nios IDE I get verify failed at address 0x01000000.

I configured unused pins as tristate inputs and triple check pins assignments so I don't know what could be the problem. Can anyone help me please?

    There is unfortunately no "quick and dirty way" to do this. If you don't have a proper timing, your design may run into problems. Are you using a kit? Aren't there example designs that you can use?

    Then you should start with the examples. If they work and your design doesn't, look for differences between the two, especially around the memory controller and the timing requirements (.sdc files).

    are you sure you put the correct .sof file and are compiling with the correct .sopcinfo description? Check also that the address used when downloading the software (0x400000 in the example you gave) is the correct one for your main memory.
