Just looking at the LS2 serial console interface, I don't have the FTDI
cable at the moment and so was considering using another ttl serial
interface ... I can't find any reference in the 9G20 datasheet though
indicating that the DRXD line is 5v tolerant, yet the serial header only
provides a 5v reference/supply (according to the schematic), with no
connection to VDDIO.
Is any additional data available on the FTDI cable sold on the shop (ie
mfg/model #, specs and/or pinout) ?
The power is 5v, but all signals are 3.3v (both on the cable and ls2
side). I would NOT use 5v signal levels.
