I have attached an image describing my problem. I have an EPT-5M57-AP-M4 board and the documentation contains images showing header names on the pins but many of them are not listed in the pin mapping chart and many of the names on the chart do not appear in the image headers. Names such as BD_INOUT0, BC_IN1, TR_DIR_1, or U7, U4, U5... I have a feeling that I'm looking at the wrong chart. Would someone please help clarify this? Thanks!
Hello, we have updated the Data Sheet for the MegaProLogic. A table was added that maps the signals from the connector pins to the I/O pins on the CPLD.
The schematic is your most accurate source for understanding how the headers correspond to pins and signal names. If you do not have the schematic, contact the manufacturer or distributor to request it.
Could you clarify which specific documentation or resources you are using? Additionally, have you checked if there are multiple versions or revisions of the documentation, which might explain the differences in the pin names?
wish you a happy and productive day Papa's Scooperia
