Hi all, I'm adapting an old code from Teensy 3.2 + audio board B to Teensy 4 and Audio board D. Before modifying the pins for the new board, I tried to run a SD card test and keep on having the message "SD card is not connected or unusable :-(". At the beginning I found the multiple library issue, which I think I solved by moving the duplicated libraries from Documents/Arduino/ Library folder but still the problem persists. Here what I get from my verbose output:

Here the code:
Hardware details: brand new teensy 4 and Audio board rev D + brand new SD card Scan Disk 128GB A2 (I also tested with other cards)
Was also wondering which pins need to be changed to adapt my old code with Teensy 3.2 and Audio board B to the new set teensy 4 and Audio board rev D?
Thanks

// do nothing after the test
}Hardware details: brand new teensy 4 and Audio board rev D + brand new SD card Scan Disk 128GB A2 (I also tested with other cards)
Was also wondering which pins need to be changed to adapt my old code with Teensy 3.2 and Audio board B to the new set teensy 4 and Audio board rev D?
Thanks
Pat
