Hi all,
on our custom board with i.MX6UL and eMMC 5.1, the bootloader doesn't recognize the eMMC.
The bootloader is loaded in serial download mode with the imx_usb_loader tool.
In uboot the following answers are shown:
mmc info => no card present
mmc dev 1 => Card did not respond to voltage select
The eMMC schematic is the same as in i.MX6UL EVK.
The u-boot is made with fsl-arm-yocto-bsp (mx6ul_14x14_evk).
Has u-boot to be modified working with eMMC 5.1?
best regrads

Hi René
is emmc working in linux or freertos (for example booting from other media like sd):
Board Support Packages (7)
SDK2.2_iMX6UL_WIN(REV SDK2.2)

one can check guidelines on
EMMC 5.0 and EMMC 5.1 work on i.MX6
