PCBindex Posted April 23, 2018 Report Share Posted April 23, 2018 Hi! I'm trying to create a library based on the "Wishbone VHDL" sample i think. I'm currently stuck trying to write to a wishbone register, the ZPUIno just locks up while the vhdl-module continues to happily tick without any noticeable changes. I've cross-referenced my code with the simple writeLeds example but I really can't see anything that should cause this lockup, please help!. ( btw I'm on an Papilio Pro board ) Here's my code:http://www.pcbindex.com/ I can see the print of line 13 just fine, line 14 initiates the write, and then it gets stuck and I never seems to reach line 15 https://github.com/telamon/papilio-dspwing/blob/865e322b7eb3d761216595fead3c85fb294811ed/examples/simple_tremolo/simple_tremolo.ino#L15 which goes to: https://github.com/telamon/papilio-dspwing/blob/865e322b7eb3d761216595fead3c85fb294811ed/DSP_Wing.cpp#L33 <- how i perform the actual register write https://github.com/telamon/papilio-dspwing/blob/865e322b7eb3d761216595fead3c85fb294811ed/DSP_Wing.vhd#L98 <-- Here i try to receive/read. and finally.. https://github.com/telamon/papilio-dspwing/blob/865e322b7eb3d761216595fead3c85fb294811ed/tremolo.vhd#L68 <-- unpack and act upon the command. but that never happens either, so i can only assume that something went wrong with the register write inside the zpuino and that the changes to the register were never applied.
