Linux/AM3352: About the TI SDK evm 05.01.00.11 boot in kernel process issue

Tool/software: Linux

Hi Ti Team,

I download the new SDK and the first step modify DDR3 type for 512M porting to my Target board, then copy MLO, u-boot.img to Pure-SD Card to power on.

but I suffer found during the kernel occur two problems, I description to below :

1. Process hangup did not continue but I don`t know why? because I only modify DDR type but old SDK 04 version without this issue.

2. if I start to the kernel to complete the current login password location, you can not enter any letters, but the 04 SDK version is no problem.

Can you give me some advice? Thank you.

Hi,

I was not at the office during the weekend. I will test this today and update the thread.
You are using custom board, right? I will try on AM335x BeagleboneBlack, can you share which TI EVM you used as a reference to create your design?

Best Regards,
Yordan

Hi Yordan,

I found that the UART connect pad joints of my motherboard were poorly soldered and could be successfully solved after re-welding.

but, I have occurred other problem, when I boot into kernel and quest enter login now, I enter the "root"

but system unable to recognize and I have tried many times but the results have failed.

The screenshot is as follows below:

Hi,

I didn't observed the following on my side:
root@am335x-evm:~# [ 114.674614] hrtimer: interrupt took 181166 ns

root@am335x-evm:~# [ 166.487098] NET: Registered protocol family 15
[ 175.782204] Initializing XFRM netlink socket

But this didn't freeze the kernel. After hitting enter the board returned to the default console:
root@am335x-evm:~#

Is your board totally unresponsive? What happens if you hit a key on the keyboard? Does it take you to the console prompt?

Best Regards,
Yordan

Hi Yordan,

I get an error when I enter my password, but I never set the root password.

Is there a way to fix this problem?

Hi,

You should not be getting localhost login: , but am335x-evm login:.. Please use the prebuilt filesystem provided with the SDK.

Best Regards,
Yordan
