Getting the ti-sdk compiled u-boot to run on TMDSAM3517EVM

Other Parts Discussed in Thread: AM3517

I have a TMDSAM3517EVM and can flash the x-loader and u-boot that come from LogicPC with an sdcard using boot.scr. The next step is to program a u-boot that I compile from TI source. I am using ti-sdk-am3517-evm-05.03.02.00 and the code sourcery arm-arago-linux-gnueabi toolchain and can configure and compile u-boot from the boardsupport directory.

$ export CROSS_COMPILE=arm-arago-linux-gnueabi-

$ export ARCH=arm

$ make am3517_evm_config

$ make

This gets me a u-boot.bin that seems reasonable, but when I load it into the board using either the boot.scr method or nand write, it does not run. I can load the u-boot.bin that comes from LogicPC with either the boot.scr or nand write methods and it runs just fine so I believe the recipe to writing to flash is working.

The question is "What am I missing that precludes me from running a u-boot I compile from the ti-sdk?"

Hi Charles,

Thank you, Krunal.

I read over this and it looks like this processor prefefs u-boot.img instead of the normal u-boot.bin. I will test out the recipe when I get to my office tomorrow.

Dear Krunal:

The link you sent me works fine. Using that, I can build an MLO, u-boot.img and uImage that run on the TMDSAM3517EVM and I thank you very much.

The next step is getting a JFFS2 root file system for the AM3517. I see a .gz file in the ti-sdk under the filesystems directory, but my quest is to understand how to re-create from source packages a JFFS2 for the AM3517.

Hi Charles,

Glad to know now things are working for you.

Building JFFS2 image is pretty simple. Below link might help you for the same.

I look at this link and it involves untarring a previously built file sysem.

What I am trying to do is re-create a baseline all from source in the normal manner. I have looked at the "building with arago" wiki page, but the recipe is stale and incomplete.

What I am lookinf for is the recipe to completely re-build the root file system from source and so far have not found it on the TI wiki pages.

I can build a complete root filesystem from source including Qt with buildroot, but it would seem reasonable that TI have a similar, working recipe for the am3517evm.
