Comment(by skliarie):
I did "dmesg | grep glamo" and attached the result to this email.
I also tried to do
cd /sys/module/glamo_mci/parameters/
echo 10000000 > sd_max_clk
echo 3 > sd_drive
But still got the following after "cat /dev/zero > /sdcard/zero":
<6>[ 255.795000] glamo-mci glamo-mci.0: Error after cmd: 0xc120
<3>[ 255.795000] mmcblk0: error -110 sending read/write command, response
0x0, card status 0x400900
I then tried to do
echo 5000000 > sd_max_clk
and got no more sdcard errors! The write speed was acceptable 2.800
MBytes/s.
Is there a way for the kernel to automatically detect such "slow" cards as
I have and adjust the clock rate correspondingly?
