Reading the NOR flash data by MFG tool.

keitanagashima — Tue, 24 Dec 2013 09:19:42 GMT

Dear Sir or Madam,

I'd like to read the data which is written in NOR FLASH and transfer the data to own PC.

Refer to following xml file.

ucl2.xml file;

------------------------

...

<CMD state="Updater" type="push" body="$ dd if=/dev/mtdblock0 of=NorImage">read NorFlash</CMD>

<CMD state="Updater" type="push" body="read NorImage" file="OutPutNor">receiving NorImage</CMD>

------------------------

Line 1 looks successful that it write the contents of NOR Flash to "NorImage" file on Linux file system.

But, Line 2 looks fail (Transfer the "NorImage" file to PC).

Does anyone find this issue?

Keita

Dear Jimmy,

I referred to your link.

But, there was only MFG tool for i.MX53.

The structure of MFG tool for i.MX6 and one for i.MX53 was different.

I found description of "pull" - Does UtpRead(body, file) transaction in ucl2.xml.

And, refer to the following code.

=====

<CMD state="BootStrap" type="boot" body="BootStrap" file ="u-boot-mfg.bin" >Loading U-boot for KM500</CMD>

<CMD state="BootStrap" type="load" file="uImage-mfg" address="0x10800000"

loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" >Loading Kernel.</CMD>

<CMD state="BootStrap" type="load" file="initramfs.cpio.gz.uboot" address="0x10C00000"

loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" >Loading Initramfs.</CMD>

<CMD state="BootStrap" type="jump" > Jumping to OS image. </CMD>

<CMD state="Updater" type="push" body="read NorFile.bin" savedfile="NorFile.bin">Getting uboot bin</CMD>

</LIST>

=====

[Result]

The contents of NOR FLASH could save.

But, it couldn't read the data which is written in NOR FLASH and transfer the data to own PC.

[Question]

Could you tell me the way of adding a pull feature to ucl2.xml?

Or, give me some information.

Hi Keita,

Maybe is going to sound silly but did you try to use a absolute path instead of a relative?

I going to test it today in order to check if the read command had a issue.

Keita San,

Sorry for the delay. I already test it 5 times and seem this feature is not working as you mention.

I going to report this to R&D in order to fix this issue.

Dear Karina,

Thank you for your reply.

> From R&D:

I understood this limitation.

But, I have additional questions.

[Q1]

When transferring within 64 KB, following CMD format right?

=====

<CMD state="BootStrap" type="boot" body="BootStrap" file ="u-boot-mfg.bin" >Loading U-boot for KM500</CMD>

<CMD state="BootStrap" type="load" file="uImage-mfg" address="0x10800000"

loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" >Loading Kernel.</CMD>

<CMD state="BootStrap" type="load" file="initramfs.cpio.gz.uboot" address="0x10C00000"

loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" >Loading Initramfs.</CMD>

<CMD state="BootStrap" type="jump" > Jumping to OS image. </CMD>

<CMD state="Updater" type="push" body="read NorFile.bin" savedfile="NorFile.bin">Getting uboot bin</CMD>

</LIST>

=====

[Q2]

Could you show me the general specified example of CMD?

[Q3]

The source code of MFG Tool is published.

If modifying the source code, is it possible to exceed 64 KB limitation?
