T2081: U-boot not responding after entering key to stop the autoboot

[noufalp90]

Hi Team,

One of our custom board uses T2081QDS SOC with 4GB of DDR. Currently we are able to port u-boot on the custom board and stop the autoboot at u-boot by pressing any key. But we are not able to execute any commands on the u-boot console. We can say it is receiving only the key to stop the autoboot but no other commands from the user. Can you please guide me with the solution or areas to check to resolve this issue?

Thanks,

Noufal

dear @noufalp90 ,

let it continue with the boot process, don't hit any key, and share, on this way,  a complete log file.

I want to check if there some message about RAM or DTS.

Hi @LFGP 

There is no issue with the RAM as seen in the boot log. PFA complete boot log. 

We are also suspecting Processor UART-RX line. Debug is going on.

Thanks,

I see you are booting from NOR, right? , so, as a test please remove the SD card (if you have one) and any peripherical device. 

[noufalp90]

Yes, We are booting from NOR. We dont have any SD card. You meant to say removing peripheral from the u-boot config and try ?

Thanks

dear @noufalp90 ,

it is necessary to re-build the image, be sure you are using the Uboot adequate version regarding the SDK.

Hi,

Thank you for your suggestion. I have downloaded u-boot from https://github.com/nxp-qoriq/u-boot/tree/git.denx.de/u-boot-2016.09.y/ since the SDK document mentioned that updated version of the u-boot is 2016.09. Still we are stuck in the console.

Thank you.

Hi @LFGP ,

I have disabled almost all other peripherals. But still not working. U-boot stuck after entering key to stop autoboot. 

PFA new boot log.

Thanks,
