How to remove options for selecting way of booting a VoCore2?

Installing and Using OpenWrt
#1

Hello,
I'm using vocore2, when I try to boot vocore2, initially there are some options are shown, on how to boot .

"
Please choose the operation:
0: Load system code then write to Flash via Serial.
1: Load system code to SDRAM via TFTP.
2: Load system code then write to Flash via TFTP.
3: Boot system code via Flash (default).
4: Entr boot command line interface.
5: Load system code then write to Flash via USB Storage.
7: Load Boot Loader code then write to Flash via Serial.
9: Load Boot Loader code then write to Flash via TFTP.
"
actually, this waits 5 seconds to select the boot process, if nothing is entered, it follows the default way to boot.
So how do I need to boot the system with 3rd option without asking for any options to enter?

it isn't openwrt, it's u-boot.

try option 4, and do a printenv.

check the bootm param value.

#3

Use option 4 then at the command prompt run setenv bootdelay=1 and saveenv.

This reduces the delay time to 1 second from 5. Setting it to 0 is also possible, but that prevents ever using the other options to de-brick the router.

Thanks for your response, I tried to follow what you suggested, but when I try to print that environment variable it says no environment variables found, and after rebooting, again I'm getting 5 seconds delay to select the boot option.

#5

then the values are hardcoded into the uboot, or you accidentally wiped the uboot data partition.

#6

What is the way to edit uboot?

#7

If they're hard-coded, you need to modify the binary itself, or replace it, if possible.

Do what @mk24 told you, then a printenv again, to see it the value's actually saved.

#8

yeah I tried but, no change at all, getting this

MT7628 # setenv bootdelay=1 
MT7628 # saveenv
Saving Environment to SPI Flash...
Erasing SPI Flash...
.
Writing to SPI Flash...
.
done
MT7628 # printenv
bootcmd=tftp
baudrate=115200
ethaddr="00:AA:BB:CC:DD:10"
ipaddr=10.10.10.123
serverip=10.10.10.3
stdin=serial
stdout=serial
stderr=serial

Environment size: 138/4092 bytes

as you see there is no bootdelay in the list.

#9

Which commands do you have available?

Run help.

And try saveenv bootdelay 1, omitting the =.

@frollic it didn't worked

#11

In that case start openwrt, and install uboot-envtools.

Try setting the variables from openwrt.

We still don't know if saveenv's doing nothing, or if it's ignoring the settings, or if the partition's gone.

#12

I assume there's no version info anywhere in uboot?
