The MLO is generated from barebox.bin with the omap_signGP tool. It seems the header is 520byte in size. You could compare these between both images. Both configuration headers are the same. I don't know though if this is enough for the OMAP ROM code to detect a valid image. Meanwhile, i took a look at the MLO. The configuration header is ok, the image size in the GP header is correct, and the loading address is the same like in the working MLO. The first instruction in the image differs from the working one (the others too, of course). So the MLO should at least get loaded and started.. strange.

You won't be able to boot the second stage barebox from Nand then of course, but still you should see some output from the first stage. What gcc version do you have?

MLO doesn't work, rest is ok
Hello, I just wanted to try the freshly generated MLO and barebox.bin on my Phytec PCM049 board (OMAP4 based). Copied both files to the FAT partition on the SD card. Unfortunately it doesn't boot, after trying to boot from SD card the ROM boot loader oviously skips to booting from UART. When i replace the MLO with a different one (downloaded a compiled one), my generated barebox.bin gets loaded and everything's fine. Is there a simple way for debugging it? It seems like the MLO does not get executed, as the ROM boot skips to UART boot... bye Norbert ___ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
