@admin Thankyou very much. I'm completely inexperienced with my new Ender 5 Pro and every step is an adventure for me.
I had the same problem with TMC Connection error.
I follow your guide here and update the firmware (simply downloaded "....Endstop.bin" and copied it in an old 2GB SDmemory without special formatting) and put on my Printer and Start and Ready for Print.
Thanks a Lot !
Next Step ... Next Adventure ! ;
