Summary
=======
This README assumes you have read README.da850. It contains some additional
information specific to building the omapl138-lcdk. The AIS file as generated
by the build is, currently, not useable due to differences in the flash
available on this board, as compared to the da850evm boards.
Flash Differences
=================
Refer to the discussion in [1] for more detail - basically the da850evm uses
SPI flash whereas the lcdk uses NAND flash to store the bootloader, and
the support isn't there in the SPL code.
It should be possible to add the support in the SPL code should someone be
sufficiently motivated.
Using the built image
=====================
The output image to use is u-boot.bin. This needs to be converted to an
AIS file as described in [1] and then flashed using the utitilty linked to
there and also described in README.da850. You _may_ be able to write using
u-boot itself, but the commands in README.da850 won't work as they write to
SPI rather than NAND.
