Quote:[*]bcm2835-sdhost: Adjust to core clock changes (4b89d07f)
This doesn't seem to work here, even when core is high.
dmesg is full of:
Code:
[34698.177894] mmc0: overclocking to 61111111Hz
[34699.977696] mmc0: cancelling overclock

with these settings:
Code:
dtparam=sd_overclock=92
core_freq=550

This is confirmed by hdparm (~25 MB/s vs. ~36) and by reading /sys/kernel/debug/mmc0/ios:
Code:
OpenELEC:~ # vcgencmd measure_clock core && cat /sys/kernel/debug/mmc0/ios
frequency(1)=550000000
clock:        50000000 Hz
actual clock:    61111111 Hz
vdd:        21 (3.3 ~ 3.4 V)
bus mode:    2 (push-pull)
chip select:    0 (don't care)
power mode:    2 (on)
bus width:    2 (4 bits)
timing spec:    2 (sd high-speed)
signal voltage:    0 (3.30 V)
driver type:    0 (driver type B)
