IMX6UL-EVK Programming NAND via L4.1.15_2.0.0-ga_mfg-tools

Hi,

I can't program the NAND flash (MT29F32G08CBADAWP) populated on U302. I have removed U303 and the SD Card from J301 and also shorted the resistor R324 (which is under the NAND footprint) . I also made sure the Boot Configuration bits are correct SW602 is setup for serial downloader and SW601 is setup for NAND. Also (BOOTCFG[7-0]=10110011 and BOOTCFG2[7-0]=00001000) and BOOT_CFG4[7-0]=00000000. Which I believe is all correct.

Also I can program the SD card via L4.1.15_2.0.0-ga_mfg-tools by calling the script mfgtool2-yocto-mx-evk-sdcard-sd2.vbs and obviously having the correct BOOT configurations for the SD Card.

But when I try to program the NAND by calling mfgtool2-yocto-mx-evk-nand.vbs and have the configurations setup as in the first paragraph it does not want to program the NAND. The Manufacturing tool Loads the U-boot, Kernel and Initramfs and then says No Device Connected and then says Erasing Boot partition and fails immediately. The output of the dbug port specifies after the Kernel has been loaded at the end where the device fails ...

Starting UTP
uuc 0.5 [built Sep 16 2016 02:36:28]
UTP: Waiting for device to appear
UTP: file/device node /dev/utp already exists
cpu_id is 0
UTP: received command '$ mount -t debugfs debugfs /sys/kernel/debug'
UTP: executing "mount -t debugfs debugfs /sys/kernel/debug"
UTP: sending Success to kernel for command $ mount -t debugfs debugfs /sys/kernel/debug.
utp_poll: pass returned.
UTP: received command '$ flash_erase /dev/mtd0 0 0'
UTP: executing "flash_erase /dev/mtd0 0 0"
flash_erase: error!: /dev/mtd0
error 2 (No such file or directory)
UTP: sending Non-success to kernel for command $ flash_erase /dev/mtd0 0 0.
utp_poll: exit with status 65280

Can anyone please assist me in programming the NAND, I have read all the forum posts relating to the NAND flash on the IMX6UL with no success.

Kind Regards

Julian
