https://community.intel.com/t5/GPU-Compute-Software/Problem-using-Bidrectional-buffers/m-p/1727951#M2187 <P>I have narrowed the problem down to a very simple project. The idea is to write two bytes to an EEPROM, read them back and create a 16bit word. Writing is successful but reading back fails in that the receiving instance sets the input register to all highs. I set an output bus directly onto the buffer;s 'output' bus (Ie the received data) and that is good. DataIn is set to " in Std_logic_vector(7 downto 0);". I tried using a simple pulse gerator using one bit and that worked but using 8 bits does not. I am completely lost as to why this occurs. I do not think I doing something wrong but will willingly 'put my hand up'if I am at fault. PS. Please,please send me an email so that I can at least say thank you. In the past anything i sent out went into a 'black hole'</P> Wed, 26 Nov 2025 16:21:18 GMT KenBee 2025-11-26T16:21:18Z https://community.intel.com/t5/GPU-Compute-Software/Problem-using-Bidrectional-buffers/m-p/1727951#M2187 <P>I have narrowed the problem down to a very simple project.
