imx6sx U-BOOT from eMMC rev 5.0

Question asked by Antonio Belussi on Jun 11, 2019

Our board mount a imx6sx microprocessor (Freescale i.MX6SX rev1.3 996 MHz ) with the eMMc  (Micron MTFC16GAKAECN-4M  Vers 5.0)

 

By command 

 * fuse prog 0 5 0x00001800 we program the microprocessor to boot from eMMC on SD4, we download the u-boot on partition 0 at address 0x400.

 

We set the BOOT_MODE 0/1 to zero (BOOT from fuses mode)

When we switch-on the board we don't see any signal on eMMC_CLK, eMMC_CMD and eMMC_RST_n and the u-boot don't start.

Do you have any suggestion ?

Thanks in advance
