A good gain in my opinion.
How is a simple documented dd if=... different? It's the same on imx, you have to dd u-boot.imx with some offset. > > I wonder, will MX28 bootrom ignore them as well?

That is, NAND driver and only after that, mxsboot for NAND _and_ SD . For now, let's hold off this patch, add the above dd stuff into documentation (doc/README.mx23) and then when all is ready, fix it all properly please. > Regards, > > -- > Otavio Salvador O.S.
