Part Number: AM5728

Tool/software: Linux

Hello,

I am using am5728 custom board. on that board while booting linux kernal through sd card it gets stuck after starting kernal msg. as follows

SD/MMC found on device 0

Hi Hardik,

Do you use AM57x TI PSDK v4.03?

Check also the below links:

Hello Pavel sir,

thanks for replying
Yes, I am using TI sdk 04.03.00.05 version...

Hardik,

Check the links provided in my previous post, these are applicable for this SDK version.

hello pavel sir,

yeah I 'av tried the changes mentioned in the link which you 'av suggested...

but kernal is still not booting up.

i 'av also tried with older version of sdk i.e. 02.00.01.07 in this sdk version after some changes it is booting up.

but we want to build kernal of sdk version 04.03.00.05

I 'av observed one more thing i.e. the rootfs size of 4.3 sdk (new version)<5.0gb approx> is much higher then 2.0 sdk( old version)<2.5gb approx>. Is it can be one of the affecting factor???

in one of the article i found in this type of case we need to modify something in dtb file

kindly suggest if any other manual changes is required to b done..

Thanks & regards

Hardik Sodha.

No, this can not be affecting factor. You have a problem with kernel image loading, while rootfs loading/mounting will happen at later stage.

You should create bootable SD card with the {PSDK4.03}/bin/create-sdcard.sh script, and you should replace the pre-built images (MLO, u-boot.img, zImage, dtb) with your own custom images. See the below wiki page for more details:

You need to make sure that you are using the correct DTB file for your custom board.

For example, on AM572x TI EVM, we use am57xx-evm.dtb file. This can be checked from the u-boot prompt:

=> echo $board_name
am57xx_evm
=> print fdtfile
fdtfile=undefined
=> print findfdt
findfdt=if test $board_name = omap5_uevm; then setenv fdtfile omap5-uevm.dtb; fi; if test $board_name = dra7xx; then setenv fdtfile dra7-evm.dtb; fi;if test $board_name = dra72x-revc; then setenv fdtfile dra72-evm-revc.dtb; fi;if test $board_name = dra72x; then setenv fdtfile dra72-evm.dtb; fi;if test $board_name = dra71x; then setenv fdtfile dra71-evm.dtb; fi;if test $board_name = dra76x_acd; then setenv fdtfile dra76-evm.dtb; fi;if test $board_name = beagle_x15; then setenv fdtfile am57xx-beagle-x15.dtb; fi;if test $board_name = beagle_x15_revb1; then setenv fdtfile am57xx-beagle-x15-revb1.dtb; fi;if test $board_name = beagle_x15_revc; then setenv fdtfile am57xx-beagle-x15-revc.dtb; fi;if test $board_name = am572x_idk && test $idk_lcd = no; then setenv fdtfile am572x-idk.dtb; fi;if test $board_name = am572x_idk && test $idk_lcd = osd101t2045; then setenv fdtfile am572x-idk-lcd-osd101t2045.dtb; fi;if test $board_name = am572x_idk && test $idk_lcd = osd101t2587; then setenv fdtfile am572x-idk-lcd-osd101t2587.dtb; fi;if test $board_name = am574x_idk && test $idk_lcd = no; then setenv fdtfile am574x-idk.dtb; fi;if test $board_name = am574x_idk && test $idk_lcd = osd101t2587; then setenv fdtfile am574x-idk-lcd-osd101t2587.dtb; fi;if test $board_name = am57xx_evm; then setenv fdtfile am57xx-evm.dtb; fi;if test $board_name = am57xx_evm_reva3; then setenv fdtfile am57xx-evm-reva3.dtb; fi;if test $board_name = am571x_idk && test $idk_lcd = no; then setenv fdtfile am571x-idk.dtb; fi;if test $board_name = am571x_idk && test $idk_lcd = osd101t2045; then setenv fdtfile am571x-idk-lcd-osd101t2045.dtb; fi;if test $board_name = am571x_idk && test $idk_lcd = osd101t2587; then setenv fdtfile am571x-idk-lcd-osd101t2587.dtb; fi;if test $fdtfile = undefined; then echo WARNING: Could not determine device tree to use; fi;

hello sir,

Thank you so much for your constant support...

Now, I have tried a bit changes in .dtb file. as I am not having deep knowledge of .dtb so changes i av made are very minute.

then too kernel booting getting stuck at one point as followed statement on terminal..

(Waiting for root device PARTUUID=58408bf4-02...

I 'av attached the log of booting terminal for your better clearity.

Thanks & Regards,

Hardik,

Running PSDK v4.03 pre-built images on AM572x TI EVM, I have the below messages:

There are several possible issues for your boot flow stuck issue: bad type of SD card, wrong SD card rootfs partition, card detect pin malfunction, wrong MMC/SD pinmux,

I notice that you are using u-boot 2015.07 with kernel 4.9.69, while PSDK v4.03 comes with u-boot 2017.01 and kernel 4.9.69. I would suggest you to switch to PSDK v4.03 u-boot also, not only to kernel. And you should create your SD card with create-sdcard.sh script, see my previous post for details.
