Hi
I have a working Beaglebone and have compiled/booted my own MLO and uImages on the bone without any problems.
I'm using "TMDXICE3359 rev 1.0A" but I'm struggling to get it to boot MLO/u-boot, any help would be much appreciated!
From "am335x-evm-sdk-bin-05.04.01.00" I have the following binaries:
-rwxr-xr-x. 1 120 nfsnobody 37403 Apr 11 14:09 MLO-am335x-evm
-rwxr-xr-x. 1 120 nfsnobody 231388 Apr 11 14:09 u-boot-am335x-evm.img
-rw-r--r--. 1 120 nfsnobody 3061672 Apr 11 14:09 uImage-am335x-evm.bin
[root@core am335x-evm-sdk-bin]#
I copied these files to the vfat partition on the sdcard as follows:
-rw-r--r--. 1 bruce bruce 37403 Jun 22 12:06 MLO
-rw-r--r--. 1 bruce bruce 37403 Jun 22 12:07 MLO-am335x-evm
-rw-r--r--. 1 bruce bruce 231388 Jun 22 12:07 u-boot-am335x-evm.img
-rw-r--r--. 1 bruce bruce 231388 Jun 22 12:07 u-boot.img
-rw-r--r--. 1 bruce bruce 3061672 Jun 22 12:07 uImage-am335x-evm.bin
-rw-r--r--. 1 bruce bruce 3061672 Jun 22 12:07 uImage.bin
When I boot I see the following in minicom:
*** StarterWare AM335x Boot Loader. Build - 1.0.0 ***
Copying application image from MMCSD to RAM
Unable to open application file from MMCSD
Copying application image from SPI to RAM
Image Copy Successful, Executing Application..
So this is probably because I didn't copy MLO as "app".... so I tried and got something different:
The sdcard now has MLO as "app" and "app.bin" (just in case):
-rw-r--r--. 1 bruce bruce 37403 Jun 22 12:19 app
-rw-r--r--. 1 bruce bruce 37403 Jun 22 12:20 app.bin
-rw-r--r--. 1 bruce bruce 37403 Jun 22 12:06 MLO
-rw-r--r--. 1 bruce bruce 37403 Jun 22 12:07 MLO-am335x-evm
-rw-r--r--. 1 bruce bruce 231388 Jun 22 12:07 u-boot-am335x-evm.img
-rw-r--r--. 1 bruce bruce 231388 Jun 22 12:07 u-boot.img
-rw-r--r--. 1 bruce bruce 3061672 Jun 22 12:07 uImage-am335x-evm.bin
-rw-r--r--. 1 bruce bruce 3061672 Jun 22 12:07 uImage.bin
[root@core am335x-evm-sdk-bin]#
And when I power on and press the rest button I get:
*** StarterWare AM335x Boot Loader. Build - 1.0.0 ***
Copying application image from MMCSD to RAM
Copying to RAM completed successfully
Image Copy Successful, Executing Application..
So I thought perhaps the "app" or "app.bin" needs to be "u-boot" and not "MLO" ... so I tried that, sdcard now looks like:
-rw-r--r--. 1 bruce bruce 231388 Jun 22 12:23 app
-rw-r--r--. 1 bruce bruce 231388 Jun 22 12:23 app.bin
-rw-r--r--. 1 bruce bruce 231388 Jun 22 12:07 u-boot-am335x-evm.img
-rw-r--r--. 1 bruce bruce 231388 Jun 22 12:07 u-boot.img
-rw-r--r--. 1 bruce bruce 3061672 Jun 22 12:07 uImage-am335x-evm.bin
-rw-r--r--. 1 bruce bruce 3061672 Jun 22 12:07 uImage.bin

and when I power on and press the reset button minicom now shows:
*** StarterWare AM335x Boot Loader. Build - 1.0.0 ***
Copying application image from MMCSD to RAM
Copying to RAM completed successfully
Image Copy Successful, Executing Application..
I'm not sure what application it's executing successfully? ...as I sure can't see any MLO or u-boot... :))
So I then tried to compile my own images. I used "ti-sdk-am335x-evm-05.04.01.00" ...which compiled everything perfectly but again I got the exact same behavior as above.
My Fedora system sees the board when I connect:

So.....how do I get away from this embedded "app" story and move to embedded linux (MLO, u-boot and uImage) ..... any help would be greatly appreciated!
Cheers
Bruce
