Subject: [PATCH] fix-glamo-mci-set-default-drive-level-0.patch
|
|
|
|
Tests on access to SD Card with Glamo drive level "0" show
|
|
that it reduces SD_CLK energy at 1.5GHz by 24dBm compared to
|
|
drive level 3. This puts it only 6dB above the background
|
|
noise floor compared to 30dB and should make a solution for
|
|
GPS trouble with SD Card in.
|
|
|
|
SD card communication seems unaffected so far on the Sandisk
|
|
512MB card we ship.
