Hangs when "Jumping to Starterware Application"

Gregg Schroeder

Hello,

I am having a problem booting over UART with the BeagleBone Black. The card slot is failing, so unless you hold the card in just right it doesn't work. So I am trying to use UART. I am using the latest version of the CCS, Starterware, etc. I compiled the boot out of the /build/armv7a/cgt_ccs/am335x/beaglebone/bootloader. I built the Release UART version, which makes the boot.out, boot.bin, and boot_ti.bin, listed in the 'binary' section of StarterWare.

I renamed the boot.bin to MLO and copied it to the directory where we will be transfering from using XModem. Next I copied in one of our binary builds. (This is a working build, called 'main.bin' that works just fine when we boot off of SD card, and use our own MLO).

I can transfer the MLO over to the board just fine using UART. It says StarterWare CCCCC.....
Then I transfer the main.bin over. It transfers fine, and then says "Jumping to StarterWare Application" .

There it hangs, and nothing more happens.

I have tried building and loading the "application name" _ti.bin files that I have renamed to "app". That makes no difference. They transfer just fine and then it hangs when jumping to the application.

What am I missing?

Thanks,

To clarify, I am not sure that the problem is with the MLO or even with UART, because when I tried to boot via sd card per the instructions at StarterWare_Booting_And_Flashing, the same thing happened. According to that all you need is the MLO and the binary that has been renamed to "app" and it will boot. I built the demo project, and used it's resulting app file and the MLO that is made to work for SD. I got the very same results as outlined above, it copies the application to the board, and then hangs at the part where it says "Jumping to StarterWare Application".

Hi Gregg,

To run the StarterWare on BeagleBone Black you need to do some changes in it. Please let me know if you have done these changes? kindly refer the following link for more information on it.

Hi Gregg,

Please mention the version of the board you are using. versions higher than A4 are having some issues with demo app. We are looking into it. You can still test the sd card booting with the LED blink example on A6 after applying the patches.

Thanks and Regards,
