Tool/software: Linux

hello

just yesterday we got a board and started it connected via uart serial port, yesterday was ok, I was able co cross compile nginx and had started it, and I did not flash it or did something for rewrite uboot of image, I just created the folder /opt/nginx and had started nginx

but this morning I can't boot :(

I have just this message and nothing moving

could you please help me what to do :((

and yesterday I robooted device 3 times and everything was ok except my files they every time disappeared, how to put it persistently I do not know

    Hi David,

    You are posting your question in DM816x forum, but from the log I see you are using TI813X (DM813x/DM38x) device which is supported in DM814x or DM3x forums:

    e2e.ti.com/.../100

    e2e.ti.com/.../716

    First of all I would recommend you to clarify for us and for yourself which TI device exactly you are using (DM816x, DM814x, DM385, etc).

    Then you should clarify what software package you are using (EZSDK, IPNC RDK, DVR RDK, etc) and which version. Then you should clarify what is you booting media (MMC/SD card, NAND, NOR, etc) and how you configure your system to boot from that media. Then you should clarify if you are using TI EVM or custom board.

    Regards,
    Pavel

    ooops I am sorry, just its written TI816X on SDK which was sent by manufacturer :( sorry for my mistake

    I am using the custom board 

    itis vivotek ND8321

    soc is Davinci SM8107AAAR2i

    the board has no SDCard slot

    I connecting to sdcard by uard Serial Port

    The OS was prebuilded NAND 

    I was needed to rebuild the image to put there crosscompiled NGINX and LUA for our future solution, I got this board 1 day before, I was able to boot preinstalled OS and just copy to /opt/ nginx and tested that nginx is working, after rebooting all my  files has gone I copy it gain just for test. on next day this board did not want to boot anymore.

    I have DVRRDK_03.00.01.03 which was sent by manufacturer to us, but I cant build my img cause manufaturer sent us DVRRDK_03.00.01.03 without dsp libraries. and I do not understand how to flash it becasue there is no SDCard slot

    I asked question about crosscompile on this forum and people suggest me to use EZSDK, I downloaded and setted up EZSDK, and compiled nginx successful but how to flash this board with EZSDK I do not know :(

    may be if I could build my own img and flash it to board I can unbrick it

    thank you very much for help

    I am not aware of such TI device. Do you mean DM8107?

    I am not familiar with that specific board, I can only provide you suggestions regarding TI81xx device in general. From what I understand, you need to re-flash your NAND with new images, but you do not have SD card to do that.

    One of the options is to flash your NAND through the TI81xx flasher tool. You will need JTAG emulator and CCStudio:

    TI814x/TI813x support also flashing NAND through UART. You might check if TI8107 has this support also:

    Also EZSDK can be used only for TI814x/TI816x devices. For TI8107 you should use DVRRDK.
