PROCESSOR-SDK-AM335X: Beagle black booting issue with TI SDK

Part Number: PROCESSOR-SDK-AM335X
Other Parts Discussed in Thread: AM3352

Hi,

I am using Beagle bone black and trying to boot it with Processor SDK Linux using SD card. I am unable to boot it and below is the log.

From the boot log, u-boot and kernel looks started ok, but somehow waiting for rootfs "[ 1.191365] Waiting for root device PARTUUID=55c1f8d5-02..."
Have you tried creating your SD card per the following instruction?

Hi Hong Guan64,

Thanks for the response. I have created my SD card in windows by following below link.

https://software-dl.ti.com/processor-sdk-linux/esd/docs/06_03_00_106/AM335X/linux/Overview/Processor_SDK_Linux_Creating_a_SD_Card_with_Windows.html

Now it started booting up properly. my LCD is up now but i am not getting expected output in display...below are the related files.

Image is not coming if i keep "straight" for blue-and-red-wiring and coming in mirror format after putting "crossed". Please guide me to proceed further.

It is good to know that u-boot and kernel boots up now on your board.

I'm looping in my colleague on LCD display inquiry.

Hello,

I am wondering if you have referred to the following silicon errata: http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/Graphics/AM3_Beagle_Bone_Black_Configuration.html. It would be helpful to understand your board configuration.

Regards,
Krunal

Hi Krunal....

Thanks for the useful link....I have followed and applied same configuration. I am getting mirror image of Matrix App launcher in my display. Below are files and please let me know where i am missing...
