Restart everything

joaomota1994

Hello! i've tried to boot the wind river linux from sd card .

i've everything like new except for the booting instructions!


First question: do i need to download an iso image and burn it to SD Card in order to start wind river pulsar linux ?


Second: I want to put everything as it came of the box. What i've done and looking to undo  is the uboot. i used this instructions and i want to undo them: https://knowledge.windriver.com/en-us/000_Products/000/060/000/030/000_Wind_River_Pulsar_Linux_Quick_Start_for_Avnet_Zynq%2C_7.0/000/020
Is it possible?

Thanks in the advance!
it's going to be a fun master thesis.

    Hello!Thank you so much for answering!

    So you're telling me that out of the box it runs Wind River Pulsar Linux OS ?

    i followed this instructions and start using uboot, but previously i didn't have it. I want to go back to whatever it was there previously because something is not working here with this (i didn't burn anything in the SD card it just went as it was) .

    I want the other thing that was there before i did this:

    1.   Boot up Pulsar Linux by performing one of the following procedures at the U-Boot prompt:

        Boot up Pulsar Linux manually:

            
        > fatload mmc 0 0x3000000 uImage
> fatload mmc 0 0x2A00000 dtb
> setenv bootargs 'console=ttyPS0,115200 root=/dev/mmcblk0p3 \
ro rootfstype=btrfs rootwait'
> bootm 0x3000000 - 0x2a00000

        Boot up Pulsar Linux automatically after saving the boot settings in the U-Boot environment:

           

        > setenv sdboot "fatload mmc 0 0x3000000 uImage && fatload mmc 0 0x2A00000 dtb ; \
             setenv bootargs 'console=ttyPS0,115200 root=/dev/mmcblk0p3 ro rootfstype=btrfs \
             rootwait' ; bootm 0x3000000 - 0x2a00000"
             > setenv bootcmd "run sdboot"
             > saveenv
             > reset

    I just want a fresh start. So i guess i'll have to mess with the booting instructions again.
