Hello,I am trying to setup a NIOS project and I would like to use the SDRAM on the board. Unfortunately, I seem to be unable to access the chip. When trying to store the software on the chip, I get the classical "Verify failed" error. I tried the memtest template and apparently, it fails right at the start with "Data bus test failed at bit 0x1". As far as I understand, this means that my SDRAM configuration is wrong. Unfortunately, I don't see where. I have a PLL ensuring that the SDRAM clock leads all other clocks and the pins are well configured. I attached my project to this post. Thanks in advance, Fofeu
Try using the system console to test if everything is working. If you are unfamiliar with tcl syntax, this is also a good place to start because you get interactive feedback of what you typed.I used to get the ''verify failed'' error too. This was because my clock or reset wasn't working properly.
