How to burn kernel and file system into Quad Nor flash

[stevenyu]

Hi Support,

We have checked MFG_TOOL , and found the tool can write uboot into flash. Would you please let us know how to burn kernel and file system into flash ? 

=== below are uci2.xml used to burn uboot into flash ===

<CMD state="Updater" type="push" body="$ dd if=$FILE of=/dev/mtd0 bs=1k seek=4" ifdev="MX6SX MX6UL MX6ULL">write U-Boot to NOR flash</CMD>
<CMD state="Updater" type="push" body="$ dd if=$FILE of=/dev/mtd0 bs=1k seek=1" ifdev="MX7D">write U-Boot to NOR flash</CMD>

<!--QSPI header-->
<CMD state="Updater" type="push" body="send" file="qspi-header.sh.tar">Sending qspi header shell</CMD>
<CMD state="Updater" type="push" body="$ tar xf $FILE "> Extracting...</CMD>
<CMD state="Updater" type="push" body="send" file="files/%norconfig%">Sending QSPI header config file</CMD>
<CMD state="Updater" type="push" body="$ sh qspi-header.sh $FILE"> Generating the ascii value header</CMD>
<!--hexdump to convert ascii value to hex file-->
<CMD state="Updater" type="push" body="$ busybox hexdump -R qspi-tmp > qspi-header">Converting ascii value to hex file</CMD>
<CMD state="Updater" type="push" body="$ dd if=qspi-header of=/dev/mtd0 bs=1k seek=1" ifdev="MX6SX MX6UL MX6ULL">Writing header to NOR flash</CMD>
<CMD state="Updater" type="push" body="$ dd if=qspi-header of=/dev/mtd0 bs=1k seek=0" ifdev="MX7D">Writing header to NOR flash</CMD>
<!--delete temporary files-->
<CMD state="Updater" type="push" body="$ rm qspi-tmp">Deleting temporary file</CMD>
<CMD state="Updater" type="push" body="$ rm qspi-header">Deleting temporary file</CMD>
<CMD state="Updater" type="push" body="$ echo Update Complete!">Done</CMD>

Hi Steven,

Here you can use the mfgtool2-yocto-mx-evk-qspi-nor-n25q256a.vbs in mfgtool to download.
Have a great day,
Rita

Hi Rita,

This vbs only write u-boot into Quad Nor Flash.

Do you know how to write kernel and file system into Nor Flash if Quad Nor Flash is big enough?

Hi Rita,

We download mfg_tool from 6ULL web site, and the embedded os is not Android Linux, it is Yocto.

this is a sample for configuration of nor flash support:

$ flash_erase /dev/mtd0 0 0 $

dd if= u-boot-mx6q-sabreauto-weimnor.bin of=/dev/mtd0 bs=128K

$ flash_erase /dev/mtd2 0 0 $="$

dd if=uImage of=/dev/mtd2 bs=128K

$ flash_erase /dev/mtd2 0 0
for more detailed information, you can refer to the mx6 AI board which supports NOR flash boot. I attached the user guide.

Hi Joan Xie,

$ flash_erase /dev/mtd2 0 0 $="$         ==> any typo here?!

dd if=uImage of=/dev/mtd2 bs=128K

$ flash_erase /dev/mtd2 0 0
for more detailed information, you can refer to the mx6 AI board which supports NOR flash boot. I attached the user guide.

It looks like commands you provided put u-boot to mtd0 and put uImage to mtd2.
