I was wrong. it isn't a timing issue. In at91boostrap, I specified the wrong IMG_SIZE, and specifying the correct size solved the problem. I had only copied part of the binary to SDRAM, which lead to the program sometimes showing the initial banner before crashing. In my situation, I use buildroot-2011.11, which downloads at91boostrap from: ftp://www.at91.com/pub/at91bootstrap/ version AT91Bootstrap1.16.zip, and though updates are the available I have modified my st91boostrap and uboot, so upgrades are not so simple. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
