iMX6SL cannot boot from eMMC when LCD is connected

Hi,

We have a cutom board based on IMX6SL EVK. Board boots when LCD is not connected to it. But we are facing an issue that board is not booting from eMMC when LCD is connected.

We also referred i.MX6UL cannot boot from eMMC when LCD is connected this link but still there is an issue.

as per above link there is a comment to disconnect LCD data lines DATA4 to DATA13 but we cannot disconnect LCD data lines. Also we have measured the POR_B voltage.

Any help to resolve this issue.

Thanks in advance

Hi Namrata

please attach jtag and check SRC_SBMR1,2 registers if they have
correct boot configuration.

Best regards
igor
