Minicom Not Taking command after booting..

[gagangarg]

hello,

I am using the following:

Board: iMX28EVK

BSP Source File : L2.6.35_10.12.01_SDK_source_bundle.gz

Host OS : Ubuntu 10.04.4

I am trying to port Bsp to Imx28evk using Linux on the host machine.

I am successful in creating bootstream image as well as file system (.jffs2) using ltib.

I have mounted it on sdcard using mk_mx28_sd script.

When I try to boot the board, I got some error. 

There are two problem I am facing.

first one is the error:

mount: mounting usbfs on /proc/bus/usb failed: No such file or directory

I cant figure out what it is trying to do.

Second one is the following error.

Yes, Vladan, It was a HW issue. Actuallt its mosfet 2N7002 was not working properly and giving the high signal to UART_ENABLE PIN. which was making the max receiving disable.

As soon as I changed the mosfet, It is working fine.

Anybody please help. Its urgent.

Error is coming from Matchbox, so I assume you built the GNOME profile? Do you need X11 and Gnome environment?

Try installing the BSP again and instead of GNOME profile choose the Minimal profile in LTIB.

Hey Vladan,

Sorry for the late reply,Actually I was working on the another project meanwhile. I do require Gnome profile.

But according to me the problem might be in the board because when I short the rx and tx pin of the uart(input line to the max ic) it is taking the input from minicom. But when i short the rx -tx line at the output of the max ic, it is not responding again.

So according to me, the fault might be lying in max ic.

What u say. Might be I am wrong.

Hi,

I was just trying to see if it’s a software issue caused by GNOME profile. I haven’t used it so not sure if it can affect, but probably not. Have not seen that type of issue with i.MX28EVK boards I have, but it’s worth checking if it is a HW problem.

Br,

Vladan

Vladan, I am not sure if the customer's issue had been resolved. If yes, please let me know. I will close the DI.

Thanks,

Looks to be  HW issue with the board. If that is the case, can be closed.

I had the same error with minicom, so i tried picocom for testing and it worked with it. So i stayed on using picocom..

Sorry I had no time yet to find the bug on my machine/constellation.

Cheers
