I too tried both computed and precalculated timing and found that both failed. X-loader works on my board so I have begun comparing the setup between x-loader and u-boot-spl. There are definitely differences in the register setup. Will spend some more time on this tomorrow. Steve ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

The spl I built is less than 32K. It seems that the issue is in RAM setup -- the RAM test fails after one word (hence it reporting 4 byte RAM size). Is your tree based on v2011.09? Is it public?

My tree has the precalculated ddr timing patch: U-Boot/SPL: omap4: Make ddr pre-calculated timings as default. All ddr configurations(geometry/timings) are done automatically by detecting the device connected at run time. Though this is a useful feature, making this as a default setting increases the code size by about 2K bytes. This is quite big, especially in the case of SPL which runs from a smaller SRAM.

[U-Boot] SPL broken for pandaboard with v2011.09?
