unable to flash yocto images to eMMC using MFGTool-iMX6SL

[jansirani]

Hai,

we are having a custom board same as iMX6SLEVK but difference is , in our custom board we mounted eMMC also.

So according to the schematic ,SD2 channel is used for boot purpose for both SDcard and eMMC.

As CD and WP pins are not required for the eMMC we commented those pin configuration in imx6sl-evk.dts

i.e

&usdhc2 {
    pinctrl-names = "default", "state_100mhz", "state_200mhz";
    pinctrl-0 = <&pinctrl_usdhc2_1>;
    pinctrl-1 = <&pinctrl_usdhc2_1_100mhz>;
    pinctrl-2 = <&pinctrl_usdhc2_1_200mhz>;
    //cd-gpios = <&gpio5 0 0>;
    //wp-gpios = <&gpio4 29 0>;
    keep-power-in-suspend;
    enable-sdio-wakeup;
    status = "okay";
};

Then compiled the images (uboot.bin,uImage and rootfs.tar).

Inorder to flash images to eMMC using Mfgtools compiled Mfg firmware images also .

when we start the Mfgtool.exe , it is getting stop at Starting Linux..... without any errors in the Mfgtools.exe.

for reference please find the attached Mfgtool logs also.

why Mfgtool is getting stop showing "No Device Connected"

How to rectify this?

Thanks and regards,

Hi Jansi Rani,

    I am trying to flash iMX6slevk board with android KK4.4.3_2.0.0-ga using MFG tool into eMMC. My board is also of 512MB RAM.I applied all the patches and flashed into board but my u-boot is not at all coming up so that I am not able to find any logs in the console.

   Is the DDR test is necessary in this case or do you found the solution for this case. Can you please help me.

Regards,

srikanth.

if hanging occurs when Mfgtools.exe  is getting stop at "Starting kernel
then it is necessary to rebuild mfg tools firmware (files in ..Profiles/Linux/OS Firmware/firmware)
with uboot changes. Please check sect.6.3 MFGTool attached Yocto Guide.

Hi igorpadykov

As we are correcly not aware how to build Mfgtoold firmware we are flashing an sdcard image as per the Freescale_Yocto_Project_User's_Guide.pdf in section 6.1

i.e $ sudo dd if=<image name>.sdcard of=/dev/sd<partition> bs=1M && sync

After flashing if we use the sdcard in iMX6SLEVK ,it will boot but the same in our custom board will stop at "starting kernel....."

 please guide where we missed?

[igorpadykov]

one can try to check cma size, defined in imx_v7_defconfig and decrease it.

Also use for debug AN4553 Using Open Source Debugging Tools for Linux on i.MX Processors

http://www.nxp.com/files/32bit/doc/app_note/AN4553.pdf

Hi Jansi

if Mfgtool stops at "Starting Linux" this may point that memory is not

working properly, please run DDR Test

https://community.freescale.com/docs/DOC-105652 

and rebuild firmware with updated calibration settings (defined in uboot *.cfg file)

for emmc dts one can look at SabreSD usdhc4:

linux-2.6-imx.git - Freescale i.MX Linux Tree

Hi igorpadykov

Thanks for the reply.

for emmc dts we will check with sabreSD board.

Mean while we want to check for Sdcard also.

As our custom board is designed same as iMX6SLEVK  sdcard images we want to check with our board.

one major difference in the boards are : in our custom board we used 512MB LPDDR2 where as in iMX6SLEVK it is 1GB LPDDR2.

so in uboot/git/include/configs/mx6slevk.h

#define PHYS_SDRAM_SIZE SZ_1G changed to #define PHYS_SDRAM_SIZE SZ_512M

compiled the images and tried to flash the images to sdcard of our custom board using Mfgtools.exe  but it is getting stop at "Starting kernel ..."

where as the same images we can able to flash to sdcard  for iMX6SLEVK and booting also properly happening in iMX6SLEVK.

Please tell us still in which places of uboot and kernel  we have to change the LPDDR2 size to 512MB in Yocto(3.10.17).

[igorpadykov]

please run ddr test and update with its results board *.cfg file located in

uboot/board/freescale/mx6slevk/

~igor

[jansirani]

After ddr test we updated read and write calibrations in the following files

$yocto/fsl-release-bsp/core-image-minimal/tmp/work/imx6slevk-poky-linux-gnueabi/u-boot-imx/2013.04-r0/git/board/freescale/mx6slevk/imximage.cfg file:

-ldr r2, =0x4241444a

-ldr r2, =0x3030312b

to

+ldr r2, =0x403e4046

+ldr r2, =0x3a363c32

still kernel is getting stuck @ Starting kernel.....
