Hello:
I've successfully booted our new board using AISgen to modify a stock u-boot-bin as well as boot a kernel and filesystem. I've followed many Wikis to get to this point and my Host Development PC is a bit of a mess so I wanted to confirm what I should be using. I started with a LogicPD AM1808 eXperimenter board and isntalled those tools but I've run across a few other Wikis that pointed to other SDKs. The most recent I found and used was the OMAP-L138 LCDK. So to begin, I'm hoping to get help to remove unnecessary downloads with the goal to modify u-boot and the kernel to match our board.
I currently have the following folders on the Host PC:
- AM1808_OMAP-L138
- CodeSourcery
- ti-sdk-am180x-evm-05.05.01.00
- ti-sdk-omapl138-lcdk-01.00.00
- mcsdk_1_01_00_02 (and a bunch of other directories from this SDK)
The reason I switched to the OMAP-L138-LCDK is because it matched our board design more closely. Our design has the following:
- AM1802
- DDR2 (Micron MT47H64M16HR-25:H)
- NAND x8 using CS3 (Spansion S34ML04G200TFI000)
- uSD connected to MMCSD0
- Ethernet PHY DP83848 using MII
- USB Port on USB0
So my questions are:
- Which SDK/sources should I be working with? The most recent work has switched from arago to linaro but I found notes that AM180x should continue to arago.
- I tried a couple of pre-built u-boot images but neither was able to successfully initialize the phy but I was able to probe using mii in u-boot and get a response. u-boot supports the DP83848 phy but I'm unclear on how to modify the u-boot sources.
- It also looks like I can add it my configuration settings from AISgen directly into u-boot but I didn't fid any real instructions on doing that so hopefully there's a link that I missed somewhere.
Thanks,
George
