Sinha:

  When you build the images, you can add the SERIAL_PARAMETER="console=tty0 console=ttyS1,115200n8" in make command option to use ttyS1 for kernel console.

  There is no configuration of serial port in kernelflinger. Kernelflinger use the BIOS boot service to output the log.

  I have not tested Celadon in 32-bit, I guest need a lot of effort to enable it.

 

  I have no idea about add the lunch target and let the GUI without Hardware Acceleration.

Hello Tan,

 

Thanks for helping!

 

Where do you change the console ttyS1?

For GRUB, I changed in the bootloader menuentry in linux line.

 

For KernelFlinger, where am I supposed to do it?

 

Also, is it possible to add a lunch target for the UP2 boards for Celadon? It could be helpful.

 

Another question: is there any way to build Celadon for 32-bit, instead of the default 64 bit one?

 

Lastly, a note from my side, I can run android-x86 8.1-rc1 32-bit ISO from the android-x86 project and live-boot android on the UP Squared. It shows up the GUI. This works with their "No Hardware Acceleration" menu entry.

  We enabled the Celadon in UP2 board in May, and it can boot to UI.

  The following need to be take care:

  1. If the ttyS0 does not work, then refer to https://up-board.org/wp-content/uploads/datasheets/UP-Square-DatasheetV0.5.pdf, use the Pin 8,9,10 in the 40Pin GP-Bus, and try to use ttyS1.

  2. Disable the trusty.

       Modify the device/intel/project-celadon/celadon/mixins.spec, set the trusty: false, and in boot-arch:, set tos_partition=false.

 

  You can also disable the trusty and try it in SKL NUC.

Hello,

I am working with UP2 or UP Squared boards: Intel Pentium version.

 

I applied the patch. Unfortunately, I could not get any output from the serial console. I can get serial console output in other cases but not with Project Celadon images. So the serial pins are working fine.

 

I tried both the GRUB and kernelflinger processes. For GRUB, I changed to console=ttyS0,115200n8 which seems to be the required one for Up Squared board. I didn't connect any keyboard or display. Still, I could not see any output on my client serial output.

 

For the KernelFligner as well, nothing comes to the console.

 

Additionally, I tried the GRUB booting process on an Intel Skull Canyon. Same issue happened: when I select any of the boot options, the screen freezes, and the keyboard stops working. I have not tried the KernelFlinger direct booting on Skull Canyon because it seems to be directly working on the hard disk without any warning, which I don't want, as of now.

 

Any clue or suggestions on how to fix this?

  Which type of UP board are you using? There are several type of UP board in https://up-board.org/.

  Can you mail me the serial log of kernelflinger to me?

  And you can try the patch of  https://github.com/projectceladon/hardware-intel-kernelflinger/pull/5 to output more detail kernel log. And the default serial port used by kernel is ttyS0, you need to check the UP board use which serial port.

 

  You can ignore the ‘Failed to get SDIO protocol’ warning and need not copy userdata.img.

I have built for the Celadon target but none of the booting processes works for Up Squared. I'm trying out the 8.1 branch.

 

For the GRUB process, I copied over celadon.img, but once I select project Celadon from the boot menu, nothing shows up, keyboard stops working.

 

For the KernelFlinger via EFI shell process, there seems to be some issue with eMMC storage. When the flashing is going on in EFI shell, I get error message as " Failed to get SDIO protocol". But the flashing continues and finally gets stuck on "flashing lock". When I remove the "flashing lock" fastboot command from installer.cmd file, flashing is completed. But then the booting hangs up in the "Intel" logo screen and never goes to the Android logo screen. Another issue was that I had to additionally copy userdata.img to the USB disk, which was not included in the KernelFlinger zip files.

  Currently Celadon has two lunch target: celadon and cel_apl.

Hello,

 

I understand that Android-IA is now merged with Project Celadon. I am wondering what the name of the target is for previous Android-IA platforms. I want to build Project Celdaon for an Up Squared machine. Thanks!
