I have a SDR104 tf card,named DH13L.But when i using it boot up raspi-os .Pi5 can't recognize it as SDR104,but only SDR25.Here is boot up log:I do more test to identify the problem.I boot pi5 with another TF card using usb3 card reader.And then insert the DH13L TF card to slot,raspi-os recognize it as SDR104,and speed goes well!It looks like,when pi5 boots up ,vc4 recognize it as SDR25,and raspi-os never re-recognize it again,So DH13L TF continuing works at SDR25 condition.
