Using DiskIISTM32 on Apple IIc with floppy switcher

[githubuser-user-ai]

Hi,

Following previous issue on Apple IIgs SmartPort, I'm testing it on Apple IIc smartport, with a Floppy switcher.
The floppy switcher allows to swap internal 5.25 floppy and external floppy drive on smartport (DB19).
This solution is working fine with a SDiskEmul base on ATMEGA328P

First, I link IDC 20 pin 12 and pin 11 to power DiskIISTM32.

Even if DISKIISTM32 is working, after some mount/unmount, it stops working, like freezing. I reset blackpill, and it refuse to mount a .woz file.
If I switch internal 5.25 as first drive, Apple IIc don't even boot. I have to unplug DISKIISTM32 to make Apple IIc works again.

On DiskIISTM32, I did not populate R1,R2 and R3. Maybe these pullup are important. I'm adding them.

Thanks, I will work on it, this is not related to the PUP resistor,
Do you have the pinout of the floppy switcher plz ?

One question about "mount" from the device
From time to time, I can't validate the "yes" when mounting a woz file ?
Is there any reason ?
I can share these .woz file (come from https://mirrors.apple2.org.za/ftp.apple.asimov.net/images/games/collections/woz-a-day/)
karateka first disk, Ikari Warrior side A for instance
