Unable to interface the memory of custom peripheral correctly

Hello,

thanks for your reply. The address is 0x0 or 0x3f I don't remember but it should be close to the lightweight bus base. But in the meanwhile I found the issue.

The avalon read process that I implemented was not complete. The else part for the "if avs_s0_read = '1' then" was missing. Therefore, the syntheziser inferred this process to be registered and clocked by "avs_s0_read". The message about the incorrectly inferred registered process was hidden among the warnings.

After implementing the else block and putting all read signals into the sensitivity list the peripheral works as expected. Although, I read in one of the threads in this community that the sensitivity list should not be the issue since it's not used during synthesizing but only for simulation.
