uSDHC3 Booting

niteshsahay — Fri, 13 Oct 2017 19:17:27 GMT

I am using iMX6DL for my application.

For booting from SD card i have considered as uSDHC3 interface but my board is not getting booted

In one of the evaluation board, which is connected to uSDHC1 is getting booted .

I have done the configuration for my board as below :

BOOT_CFG2[4:3] --- 10.

Can anyone let me know the possible reason for such occurrence.

Regards

Nitesh

Hi Nitesh

please check with oscilloscope if signals are present on SD and

try to prolong POR up to 0.8-1 sec. Also recommended to attach jtag

debugger and check boot settings in SRC_SBMR1,2 register, they are

decribed in Chapter 60 System Reset Controller (SRC).

Best regards
igor
