one basic question regarding boot_cfg and sd card speed.
The sd card speed is defined by BOOT_CFG parameters.
After successful boot does linux rely on the boot_cfg settings or is sd card speed auto-detected?
As an example, if I specify BOOT_CFG to SDR12 but SD card supports SDR104. Does linux automatically switch to SDR104 or do I need to correctly specify BOOT_CFG?
Thx in advance!
