Omap5432 debug uart

Hello Wending,

The procedure for installing USB to serial is explained here:
http://omappedia.org/wiki/Support_Tools#Installing_USB_to_Serial_on_PC

For the last step, which is

"Once the above steps are taken select the Virtual COM port that will be used by Teraterm or Hyperterm"

you should use the configurations listed in the GLSDK Software Developers Guide, section Setting up TeraTerm:

Unknown device issue may be appear, when you plugged device before install driver, so  first remove usb node from device manager, unplug USB, them to reinstall FTDI, plug USB again.

Best luck.

Hi Yordan - I am working on your Omap5 uEVM and having trouble getting the UART to connect properly. I am performing all the steps as listed in your URL above, but what I get in my terminal is a repeating pattern of this:

t°b$U @D(¢ @ü£
t°b$U @D(¢ @ü£
t°b$U @D(¢ @ü£
t°b$U @D(¢ @ü£
t°b$U @D(¢ @ü£

The EVM is continuously printing this to the terminal, I have experimented with all the various baud rates and other configs on the serial port, and no matter what I just get some sort of repeating random text. The driver installs seemed to go fine and behaved as you outlined in your example. Is it possible I have a bad unit? Any tips would be appreciated.

Thanks in advance,

Chris

You are using windows XP on your host machine, right?

Have you configured everything as stated in the Software Developers Guide wiki: http://processors.wiki.ti.com/index.php/OMAP5_GLSDK_Software_Developers_Guide? Especially the part entitled: Configuration of ARM Linux development Environment

You won't be able to flash & start your uEVM without installing & properly configuring ubutu based virtual machine.

Did you try serial flasher utility to flash boot loader? 

If you can't flash it properly than we can doubt on board itself.

Another thing that comes to mind, if you have followed the configurations from my previous post.

When you said you got your console to print:

t°b$U @D(¢ @ü£
t°b$U @D(¢ @ü£
t°b$U @D(¢ @ü£
t°b$U @D(¢ @ü£
t°b$U @D(¢ @ü£

Can you verify the sysboot switches. I got a similar result (dummy characters on my console) when sysboot switches are not configured properly.

In my case I was trying to boot from sd card with sysboot cofigured as (from 1 to 4) 1010, when the proper configuration is 0101.

Best Regards,

Yordan

Thanks for all the tips Yordan. You were absolutely right on the first one - I was accessing the EVM thru a Win7 host. So I worked yesterday and still on it a bit today to set up an XP environment with Ubuntu and Virtual Box. So I am on that path and should know something later today.

On the switches - I am almost certain I went thru all possible combinations, but not sure - after I get the proper XP environment setup I will check this out further. Chris
