GOTEK SFRKC30.AT2 with AT32F415KBU7-4MCU QFN32

Hello,

I just bought a GOTEK SFRKC30.AT2 (AT32F415KBU7-4MCU QFN32) with FLASHFLOPPY 3.39 flashed for my Amiga 1200.
It boots up and USBs keys are fully detected. However, I did not succeed making Amiga read any of my adfs.
(Symptoms: The tracks counter increments rapidly up to 255.0 but the adf is not read)

I flashed The IO-test (3.39 and 4.7a versions) to check the IOs of the chipset and observed that the following pins are stuck reading as LOW, even if 5V is applied:

  • LCD 1: Drive Select B
  • LCD 2 (floppy-16): Motor On
  • LCD 3 (floppy-18): Direction
  • LCD 7 (floppy-32): Side/Head Select
    (numbers 1, 2, 3 and 7 never appear)
    Any idea about this issue would be much appreciated.
    Thanks by advance

Drive Select B and Motor On are unconnected on AT2 and will always read as LOW.

Pins 18 and 32 should work. So, perhaps the Gotek is broken?

Thank you for your reply and for your complement of information regarding the "drive select" and "motor on" pins .
I'm afraid you are right: perhaps my Gotek is broken :-/
