I have run these two command, on the eval board works normally. but on our board, we use the same method, it's not work.

Dear Linz.

per discussion, it works well with SD card boot mode and goes to Linux console successfully.

when switch to Primary BOOT MODE (EMMC BOOT), you have measured the signal on EMMC I/F. there is no wave on data line, even clock line.

so would you please help use JTAG to read the register which store BOOT MODE PIN status? then do first check.

thanks a lot!
