LattePanda Forum

Recently we've received a lot of feedback from users that alpha's power-on function is very much needed in their project, so we decide to release a Beta version first.
Since this Beta version is not perfect at present, if you have any questions, please reply to the post.

PLEASE NOTE:
Although in our tests, there is no failure to boot after reflashing the BIOS, please back up your files in advance, and do not remove the power supply during the reflashing process, so as to avoid serious consequences.


How to set your Alpha auto power on?

Download Alpha BIOS file with Auto-power-on feature.
Alpha m3-7y30: https://www.dropbox.com/sh/tf7xiduni3b1 ... Bt3Ca?dl=0
Alpha m3-8100y KR300: https://www.dropbox.com/s/tnuc1czx7pagm ... S.zip?dl=0
Alpha m3-8100y KR310: https://www.dropbox.com/s/dgk7u2rw7qq1g ... n.zip?dl=0

NOTE: Please choose the right BIOS file according to your LattePanda Model(pls check the CPU model and S/N number).


A.First Reflash.
1.Format your USB disk to FAT32 and change the drive name to "WINPE"
2.Copy the right BIOS files directly to root of the USB flash disk
3.Plug the U-disk in USB host
4.Plugin the power cable and boot up the system
5.Press “ESC” and go into the BIOS setting page
6.Select the item “UEFI: Built-in EFI Shell” in Boot Override and press “Enter” 7.Wait few seconds until the page show “Shell>” 8.Input “fsX:” then press “Enter” (X could be 1,2,3…)
9.Input “dir” then press “Enter” to check the file in the disk.

(Explanation of some DOS commands:
cd: the cd command either displays or changes the current working directory;
dir: The dir command displays the contents of a directory’
You can find more commands in Wikipedia, https://en.wikipedia.org/wiki/List_of_DOS_commands) 10.Input “Fpt –f xxx.bin” then press “Enter” (You can use “Tab” to fast choose the bios file) 11.Wait the refreshing of the BIOS automatically until returning “ fsX:>” 12.Restart the system via pressing "Ctrl+Alt+Del".
(Please be sure to restart the system before your second reflash)

B.Second Reflash
1.Press “ESC” and go into the BIOS setting page, do Same procedure as the “First Reflash”.
2.Please use the code “ /u XXX“to start the installation “ eFuitX64.efi”, then press “Enter”. (You can use “Tab” to fast choose the bios file) 3.Wait the refreshing of the BIOS automatically until returning “ fsX:>”. 4.Remove the U-disk and unplug the power cord.(PLEASE be sure to power off the system)

Now you Alpha can wake when there is power connected to it.

Is "Auto Power ON" a user configurable toggle in BIOS menu or once this version of the BIOS is installed, this setting will be permanent?

Thanks!

I flashed the 2 files successfully , no problem. But it doesn't power itself like it should, and I can't find any options in the BIOS...

This setting will be permanent.

Hello.

We have followed the procedure as explained in the tutorial, but the auto-power on DOES NOT work.
The only difference between your tutorial and we did was that, on Section B, when we select the item “UEFI: Built-in EFI Shell” in Boot Override, the Panda simply reboots instead of entering the Shell. On a second reboot, it goes to the shell as described.
We have repeated the procedure 4 times, with two different USB drives, with the same result.

Any suggestions?

Thank you,
Carlos

same issue here.
BTW I check the date modified of the bios and ec file, was 03.13.19 not as the pic in your tutorial 04.23.19.

Hi Panda Lovers ,

If it is helpful, Auto power-on beta version run across 12V power connector (for me, at least) not across usb-c connector , and is an automatic settings.

Greetings

Thank you. Indeed it is working when it is powered with the 12V power connector. Since this will be the actual usage situation, out problem is solved.

Absolutely fantastic to see this arrive finally. It has been a very long impatient wait for many of us, but it is looking bright!

To help team lattepanda out a little bit, I've taken some proper screenshots for those who have a hard time following along with the provided images;

Download the files provided in the first post, unzip them and put the files directly in the root of a USB drive (formatted as FAT32 with name WINPE) and plug the USB into your Lattepanda.

1. Boot your Lattepanda and press and hold ESC to go into the boot menu.
2. Navigate to Save & Exit. Under Boot Override choose UEFI: Built-in EFI Shell


3. Identify your USB Drive by looking for Removable HardDisk in the list. Take note of the fs number in yellow.
4. Input your USB FS number (mine is fs3 as shown in the image) followed by : and press enter. e.g. fs3:


5. Now type dir and press enter. This will list all content on the USB Drive


6. type in Fpt -f BIO now press TAB to autocomplete the filename. (Fpt -f BIOS-S70KR200-101-B2.Bin)


7. Press enter and the Bios Flash will start. Once finished, the screen will read FPT Operation Successful.


8. Type exit and press enter this will bring you back to the BIOS menu.
9. Navigate up to Save Changes and Exit press enter and confirm you want to save configuration and exit.


10. Device will now restart. press ESC again to go into the boot menu.
11. Navigate to Save & Exit. Under Boot Override choose UEFI: Built-in EFI Shell.
12. Again type in fsX: as you had before (where X is your fs number. Provided you have not removed the USB drive) and press enter.
13. Type in eFuitX64.efi /u EC-S70KR200-101-B2.bin and press enter.


14. ITE Flash Utility will load and do some fancy flashing. Wait until it says Update EC Rom successfully!


15. Type exit and press enter this will bring you back to the BIOS menu.
16. Navigate up to Save Changes and Exit press enter and confirm you want to save configuration and exit.


17. Device will now restart.
18. Job Done happy auto booting on power!

I hope this clears things up a little bit for some of you. I found the original a little difficult to follow.

Thanks Lattepanda for coming through on this. Lots of us have been waiting for this for a long time. Keep it up! Looking forward to what project people are going to be doing with this.

Have any one got this working with the provided usb-c power supply?
