May I use 4 data bit micro Card for i.mx6, SD card boot?

[MehmetAliIpin]

Dear Sir/Madam,

Hello,

We are developing  an i.mx6 based system. We wish to boot from SD card. In the development kit, I see an 8 bit SD/MMC card connector is used and all 8 data bits are connected to it. But 8 bit SD/MMC card is not easy to find and may be expensive then 4 bit micro SD card connector. Therefore, if I use 4 bit micro SD card connector, shall I have U-boot/linux kernel problems to boot from 4 bit interface?

Best regards.
