For RAMMODE programming set with DPRAM32 or SPRAM32 or SRL16 the DI2 input pin must be connected. ERROR:PhysDesignRules:1385 - Issue with pin connections and/or configuration on block:<system_stub/system_i/axi_iic_0/axi_iic_0/X_IIC/FILTER_I/SDA_DEBOUNCE/M shreg_Noisy_d2>:<LUT_OR_MEM6>. For RAMMODE programming set with DPRAM32 or SPRAM32 or SRL16 the DI2 input pin must be connected. ERROR:Bitgen:25 - DRC detected 2 errors and 58 warnings. Please see the previously displayed individual error or warning messages for more details. I was hoping that HDMI is the only thing not supported with http://www.adapteva.com/white-papers/parallella-platform-reference-design/ There are only two pins for axi_iic: NET iic_scl LOC = AA18 | IOSTANDARD="LVCMOS25"; NET iic_sda LOC = Y16 | IOSTANDARD="LVCMOS25"; and these aren't ones mentioned in the error. I don't know how to solve this and I lost internet access - there was a thunderstorm and lighting struck my house, router is one of the things which don't work. I implemented bcrypt's most costly loop in verilog (not tested) and I have implementation of S box transfer (at the moment without DMA, just using mmap and memcpy) from CPU to block RAM (I'm still not sure how to implement communication from PL to CPU). I need to modify verilog implementation depending on PS/PL communication. And unfortunately, only way I can test communication is by executing it. I see two possibilities which could result with us being able to replace bitstream - one is replacing boot image with Sylvain's files and another one (if HDMI really is the only not supported peripheral) is generating bitstream with HDMI support.
