How to reflash or recovery initial bootloader(SPI-NOR flash) on IMX6 Sabrelite platform

chintakanisiva — Thu, 30 May 2013 04:38:51 GMT

Hi All,

When we tried to update the initial boot loader(u-boot) on IMX6 sabrelite quad core platform, some how SPI-NOR flash completely erased and not yet recovered.

We have followed some of the links which is mentioned below to recovery the SPI-NOR boot loader, but we haven't succeeded and we struck at this step. And in this case on serial window nothing has displayed once power up the IMX6 board.

i.MX6x SABRE Lite SPI Flash Recovery - Linux on ARM - eewiki

http://boundarydevices.com/unbricking-nitrogen6x-sabre-lite-i-mx6-board/

Can any one help on this, how to get back the board into normal mode working mode.

Your suggestions are very helpful for us.

Thanks all in advance.

Thanks & Regards

Ch.Siva

Hi Siva,

What I would suggest is that you program the SPI NOR u-boot using Freescale Windows-based MFGTool in in android_jb4.2.2_1.0.0-ga_tools.tar.gz.

While it "officially" does NOT support sabrelite board (at least that's what it says in MFGTool configuration file :smileyhappy:), I was able to hack it to reprogram the initial bootloader. Get a start on this and keep me posted. I'll reply on monday.

Cheers,

Sriram

Hello,

I have used this 2 links plus this one :https://wiki.linaro.org/Boards/MX6QSabreLite

I did it successfully so make sure to follow this basic steps :

* Get back a u-boot that is actually working (for instance the one in the MFG tool directory) for imx6qDL

* Paste it to a sd card, on a fat partition or in a raw partition using dd (that's the one I prefer)

* Set your card in Recovery mode like described on boundary devices website

* Follow the steps described on boundary website with imx usb loader. Right now you should see something on your terminal, if not verify the configuration of your terminal

* Now you have access to the prompt u-boot. Copy the new bootloader in NOR using the way described in the wiki of your first link (if you chose the "fat" way) or the one of the linaro's wiki (if you chose the "raw" way).

* Set your card in normal boot and reboot

Good luck !

That happens to me once. I used the Manufacturing tool and choose 'Sabre-lite-SPI_NOR' profile. Flash and boot the board. You should be able to see u-boot running.

Yes right, sorry I introduced the "hard" way !

Thanks for all your inputs,

We have succeeded to recovery the NOR Flash on iMX6 sabrelite using the instructions provided in the following link

http://www.eewiki.net/display/linuxonarm/i.MX6x+SABRE+Lite+SPI+Flash+Recovery

by following above instructions you will get u-boot prompt in minicom and from there you can update your SPI-NOR with the updated U-Boot.

Thanks

Hello community ,

i have the same problem that no output from console of u-boot or linux

but i have SD corrupted , so i tried i.MX6x SABRE Lite SPI Flash Recovery - Linux on ARM - eewiki to delete and repartition SD card , copy files but still no output comes out

My question is : what are the files really needed to be on SD card to just be able to replace corrupted U-boot (i think ) with U-Boot binary from SD card ?? and how this process happens if SPI-NOR itself has been trashed (as i think too) ??

mentioned link just copy one file to SD card , Boundary devices adds boot/upgrade script files .Linaro link here copied one file usdhc3/4.bin to SD card to be flashed into the SPI NOR in assumption SD has valid U-boot binary/Linux image ??

how do files differ with each situation/problem ?!

my situation is :
-no output from console cable at able (U-boot)

-can not use MFGTool (USB cable is not detected at all)

-can not use JTAG image download (for any U-boot /application demos) : connection reset by peer

-SD corrupted : tried to format,repartition, copy file to it , still no output at all

i really got confused and stucked with no progress ..

any help is really appreciated ..

Best Regards,

SD: to reflash a SD, in a linux console type the following command

'dd if=good-u-boot.bin of=/dev/sdX seek=2 skip=2 && sync

SPI-NOR: Try latest manufacturing tool and set choose the SPI-NOR profile

Hello Leonardo ,

thank you

i tried many times to copy files to SD card but the problem is that U-boot does not get running to be able to copy good-u-boot.bin to SPI-NOR ..

for MFGTool , i can not use it as USB cable is not detected by MFGTool.exe ..

the same cable problem prevents me from using Boundary devices USB_loader utility .

Thanks and Best Regards ,

Hi Leonardo,

This sounds like a hardware problem of some sort. Our experience is that the RBL just works...

Nehal and I had some back-and-forth on our blog and it sounds like this board is messed up somehow.

Hi Eric

We are also having a similar board as mentioned by nehal.

We tried to enable the booting of sabre lite board from SD card and during the process erased the contents of SPI NOR.

We followed the steps mentioned in Boards/MX6QSabreLite - Linaro Wiki

After this initially board was getting detected as a HID device.

But after some time we are not able to communicate to the device through USB.

Can you please help me how to determine if the board has gone bad or is there any way to recover it.

Prasad

Hi everyone ,

>I'm currently working on an IMX6 Sabrelite and managed to brick it

I)No activity on terminal,

II)USB not recognized under USB mode(01) (Windows PC "USB device not recognized" and on Linux unable to enumerate the USB device).

after i'd been flashing SPI-NOR several times to switch between platforms. Now i'm trying to get the board up i.e. see U-boot run on board and send message to terminal.

>From what i learned, imx6 boots based on FUSE SWITCH[0:1] configuration to particular media. In my case with any config[00,01,10] i couldn't get the board run(Even i tried 11 freescale reserved config ).

>In all cases the green light indicating power glows and with SDslot and Ethernet port i could see lights glowing on connected condition, but serial port remains clean with no messages and USB connected on Host(Windows PC) not recognized(USB VID/UNKNOWN). which used to be detected as HIF device under 01 configuration previously.

>So with USB flashing not possible via MFG tool or sbloader(as its detected as UNKNOWN device and not as HIF device) ,

what could be done to get the board run i.e.

1)Is it possible to Program U-boot to SPI-NOR flash under this condition

2)Use SD-CARD or any other media on-board to run U-boot fro once after which i'll be able to update SPI-NOR flash easily.

Please reply on this as its a fairly new board and would be highly helpful on my project.

Hi Everyone,

Is anyone able to reflash original bootloader to SPI-NOR flash.

We followed the steps mentioned in https://wiki.linaro.org/Boards/MX6QSabreLite : for boot from SD.

but after that it erased original bootloader from Flash. No prints comes on serial console.

We tried Mfg Tools with "MX6Q-Sabreauto-SPI_NOR & SD card" profile but still no luck. It is not giving any prints

on serial. Is it possible to put u-boot on SD card and boot from that or it mandatory to put original bootloader to

SPI NOR flash to getting it functional.

Please help me to resolve this.

Thanks,

You should use either imx_usb (under Linux) or SB_LOADER.exe under Windows as described in these two posts:

Hey! Thank you for advice!

I am stuck with after that command.

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

...

loading binary file(../u-boot.mx6qsabrelite) to 177ff400, skip=0, fsize=5bc00 type=aa

<<<375808, 375808 bytes>>>
jumping to 0x177ff400

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

Than.

Nothing happend! Do I have to change the mode of swich? or Do I have use command screen???

Or any other way?

I already failed to using way that based windows.

Any tiny hint will be great ! Thanks !

The "jumping to..." message says that the binary was downloaded and should be running.

If you're connected with a terminal emulator to the console port, you should see output from U-Boot.

Hi, Eric!

The same problem.

The original boot loader was on the SPI-NOR has been cleared.

USB otg port is broken so it is not available.

Anything can boot only to SD card.

Thanks and Best Regards ,

James
