I'm trying to measure the speed of the SDHC memory card slot of the LS1043A evaluation board, but for some reason I can't get faster than ~13MB/s. Is this the maximum? In UBoot, it seems there is no possibility to set it to more than 4 bit bus width either. The processor itself should support an embedded eMMC 4.5 card in 8 bit mode, which should support HS200 mode according to the datasheet. Is there a manual/tutorial where I can find the correct setup? I'm guessing I'm doing something wrong... The card used for the test is an UHS1 card with 80MB/s device (measured in a PC). The on board flash memory has similar speeds as well.
