imx6dl nand boot fail error code

[mtbrewster]

We have a custom board with an imx6dl processor that we are trying to boot from NAND. The boot fails and returns to the usb serial downloader. Is there any information, like in the log buffer, that we can read with the jtag to indicate what failed?

We have programmed u-boot, kernel, dtb, and fs with using mfg tool.

Hi Yuri,

I filled out a support request but here also is my email: mbrewster@vpieng.com.

I have not run the stress test. I will look into that today. I have downloaded uboot, kernel, dtb, rootfs via mfg tool, rebooted and downloaded uboot via mfgtool and then booted linux using the NAND flash. Linux comes up and I can log in. I have just done a few minimal things like poke around the file system and dump some nand pages.
