We are checking a booting from the eMMC (Ver5.0) device.
When Bus configuration is set to 8bit (BOOT_CFG2[7:5]=010) , system is able to boot.
Bus configuration is set to 8bit DDR (BOOT_CFG2[7:5]=110) ,system is not able to boot.
We hope to get the information about difference between them ( boot_cfg2 settings).
Could you tell us the starting sequence difference ?
Is it different in issuing command type ?
Is it different in issuing command timing ?
... and so on.
