IMX.258 uboot and uImage update without Mfgtool

recepyigitbasi — Wed, 21 Jun 2017 11:01:01 GMT

Hi Everyone.

I have an IMX.258 board and I want to update u-boot and uImage without MfgTool. Previously, board is programmed with Mtgtool. I can access to telnet console. u-boot and uImage files in filesystem.

rootfs has nandwrite and flash_eraseall commands and ability to write flash is successful. After write process, I am getting a dump with nanddump command. I am able to see the same file contents.

Mfgtool ucl.xm file contents here;(This is working)

<LIST name="UpdateUImage" desc="update kernel">
<CMD type="find" body="BootStrap" timeout="60"/>
<CMD type="init" body="Memory" file ="mx25ddr2.xml" />
<CMD type="load" file="uImage" address="0x80100000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" >Doing preLoad."</CMD>
<CMD type="load" file="initramfs.cpio.gz.uboot" address="0x80800000" loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" >Doing preLoad."</CMD>
<CMD type="load" file="u-boot.bin" address="0x83F00000" loadSection="OTH" setSection="APP" HasFlashHeader="TRUE" >Loading OS image.</CMD>
<CMD type="jump" > Jumping to OS image. </CMD>
<CMD type="find" body="Updater" timeout="180"> Wait for MSC device. </CMD>
<CMD type="push" body="mknod class/mtd,mtd0,/dev/mtd0">create new node: MTD0 </CMD>
<CMD type="push" body="mknod class/mtd,mtd1,/dev/mtd1">create new node: MTD1 </CMD>
<CMD type="push" body="mknod class/mtd,mtd2,/dev/mtd2">create new node: MTD2 </CMD>
<CMD type="push" body="mknod class/misc,ubi_ctrl,/dev/ubi_ctrl">create new node: ubi_ctrl </CMD>
<CMD type="push" body="$ flash_eraseall /dev/mtd0">Erasing image partition</CMD>
<CMD type="push" body="$ flash_eraseall /dev/mtd1">Erasing kernel partition</CMD>
<CMD type="push" body="$ echo 1 > /sys/devices/platform/mxc_nandv2_flash.0/disable_bi_swap">disable bi swap</CMD>
<CMD type="push" body="send" file="files/u-boot-signed.bin">Sending signed u-boot.bin</CMD>
<CMD type="push" body="$ nandwrite /dev/mtd0 $FILE -p">Flashing firmware</CMD>
<CMD type="push" body="$ echo 0 > /sys/devices/platform/mxc_nandv2_flash.0/disable_bi_swap">enable bi swap</CMD>
<CMD type="push" body="$ free && echo 3 > /proc/sys/vm/drop_caches && free" timeout="60">release memory</CMD>

<CMD type="push" body="send" file="files/uImage">Sending uImage</CMD>
<CMD type="push" body="$ nandwrite /dev/mtd1 $FILE -p">Flashing firmware</CMD>
<CMD type="push" body="frf">Finish Flashing NAND</CMD>
<CMD type="push" body="$ echo Update Complete!">Done</CMD>
</LIST>

Similarly, I am using these commands to program uboot and uImage in runtime(This is not working)

flash_eraseall /dev/mtd0
flash_eraseall /dev/mtd1
nandwrite /dev/mtd0 /home/user/u-boot-signed.bin -p
nandwrite /dev/mtd1 /home/user/uImage -p

But OS is not booting because after power off and power on, device is opened in programming mode.

Notes:

*Files using for programming are the same for both cases.(image files in filesystem and Mfgtool image files)

*Without u-boot write, only uImage write is working and booting successfully

Your suggestions are appreciated. Thank you

Regards

Hi recep

for nand programming without MfgTool may be recommended to use ATK Tool :

Programmers (Flash, etc.) (2)
Flash tool for downloading, programing, dumping and erasing images in Flash memory to the i.MX EVK(REV 1.71)
http://www.nxp.com/products/automotive-products/energy-power-management/pmics/power-management-for-i.mx-application-processors/i.mx25-product-development-kit:IMX25PDK?tab=Design_Tools_Tab

Hi igor

The main purpose of the programming via console is remote kernel update. Thé board must update kernel itself. I have to program via console or native application in file system

Thank for your reply.

Hi recep

there are ATK sources on that link so one can write own custom

application for such purposes.

Does Custom application run in board itself(for arm)or other machine(win 10)?

There is a Source code for atk on that link. But it's extension is exe.
