I have now at least got it to the point of getting a barebox prompt via the serial port. The final thing I had to change was that I realized that since we have our UART1 using a different set of pins than is the default, I needed to manually change the IOMUX settings for the early bring-up of the serial port that Sascha pointed me to earlier. Basically: /arch/arm/boards/variscite-mx6/lowlevel.c -writel(0x4, iomuxbase + 0x01f8); +writel(0x03, iomuxbase + 0x0280); +writel(0x03, iomuxbase + 0x0284); +writel(0x00, iomuxbase + 0x0920); MANY THANKS!!!! I'm sure I will have more issues, but this at least gets things booting up enough to where I can now make progress. _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
