Hi,
Recently we're optimizing the boot time of TDA4VM, we configure eMMC card Boot bus condition register(Extcsd[177]) to the value of 0x12, which means to boot at the high speed ddr 8bit mode, we found that TDA4VM don't support this mode and boot fails, we have confirmed that eMMC card support booting at the mode of high speed ddr 8bit, and when we configure the eMMC card Boot bus condition register(Extcsd[177]) to the value of 0x02, which means to boot at the back compatible 8bit mode, TDA4VM can boot successfully, does TDA4VM support high speed ddr 8bit boot mode?
