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: https://www.dropbox.com/s/tnuc1czx7pagm ... S.zip?dl=0

NOTE: Please choose the right BIOS file according to your LattePanda Model.

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

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...

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.

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
Image

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:
Image

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

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

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

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.
Image

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.
Image

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

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.
Image

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.
