And comparing that with the pinout mentioned on the TF328 flashing page, I can clearly see signals and their positions for GND, TCK, TDO, TDI and TMS.



What about VREF? Should it be 5v or 3.3v from the Pi GPIO? I am guessing 3.3v.



Also, the A600 should be powered on or off during flashing?
According to datasheet it accepts 3.3v and 5v, but it is optimized for 3.3v.

A600 must be on, the cpld gets the power from the host computer, not from the programmer.
