Newbie in need of help with BeagleBone using CCS

Thomas 50104

I'm struggling a bit getting the Beagle board to work in CCS (StarterWare is installed). I read the getting started manual still I haven't been able to run the simple GPIO LED project. I did manage to get the browser IDE up running easily but the CCS approach just wont work. The hardware seems to work fine.

The board is connected to the PC using USB. The flash card in installed and mounts fine.

I import the GPIOledBlink project to CCS and it builds with no errors. I copied the bbone-target-config.ccxm file to the target-directory and I can launch it fine and sometimes I can connect to target but sometimes I can't. When I can't I get this message:

Error connecting to the target:
(Error -151 @ 0x0)
One of the FTDI driver functions used during
the connect returned bad status or an error.
The cause may one or more of: invalid emulator serial number,
blank emulator EEPROM, missing FTDI drivers, faulty USB cable.
Use the xds100serial command-line utility in the 'common/uscif'
folder to verify the emulator can be located.
(Emulation package 5.0.569.0)

When that happens I pull the USB cable out of the computer and restart CCS and I can then launch the target fine and the debug windows prompts that the CortexA8 is suspended. I'm guessing at this point everything is fine?

In the gpioLEDblink code I commented out everything in the while(1) loop such that I expect no LEDs to toggle but when I press F8/resume then the LEDs starts to toggle in some random manner; my code doesn't seem to get to the board.

I'm hoping that some friendly soul out there can provide me some direction here because I can't seem to get this simple project to run.

BTW I'm new with Eclipse+BeagleBoard so I might have missed something fundamental here.

Thanks

Is your uboot/Linux in a known state?

I usually cancel Linux boot (i.e. "Hit any key to stop autoboot:") in uboot console and connect CCSv5 every time.

Hi Joe,

I'm not aware of the state of uboot/Linux but I can see that being a problem. Can you please tell me when you press the key to stop autoboot? Is that during CCS operation?

I'm thinking maybe I missed some important documentation so if there is something on this topic can you please direct me to it?

Thanks

There should be docs on the microSD card that came with the Beaglebone (and also here: http://beagleboard.org/static/beaglebone/a3/README.htm)

Typically you see uboot in a terminal app like Hyperterminal or putty on Windows or picocom/minicom in Linux. Above Readme has details (and you will need the microSD card that came with the Beaglebone for uboot/Linux filesystem)

Hi Joe,

Thanks a bunch!

I have looked at the link you shared, which I also had read earlier, but I can't find information on how to avoid booting in Linux; at least not some explicit recipe (I basically have no experience with Linux so digging through all the Linux material is a challenge for me). I would like to work in baremetal/no-OS "mode".

I wonder if there already is some image (a file containing everything I need to put on the flash card) shared that bypasses Linux so I can work in CCS without having to worry about an onboard OS?

I'm in the process of designing a audio daughter board working with the BeagleBone to enable algorithm development for audio. If someone thinks the BeagleBoard is not a good choice I would appreciate a comment on why that is.

Thanks

Tom

Try AM335x Starterware:

http://processors.wiki.ti.com/index.php/Quick_Start_Guide_StarterWare_02.00.XX.XX_(supports_AM335x)

http://processors.wiki.ti.com/index.php/StarterWare_Getting_Started_02.00.XX.XX

Works great on Beaglebone and/or the EVM. No OS necessary. And you can use a choice of tool chains (including CCSv5).

For flashing:

http://processors.wiki.ti.com/index.php/AM335X_StarterWare_Booting_And_Flashing

gives you choices for standalone. But I would do that LATER after getting familar with Starterware (i.e. cancelling Linux boot in uboot and loading .out file with CCSv5)

Hi Joe,

Thanks again for your support!

I'm now up running in CCS. Found out that I used the wrong target configuration file (*.ccxml)
