Hi Joshua,

     I download and extract 02LinuxShipmentImage_Debian.zip, get MaaXBoard-LinuxShipmentImage-Debian-V1.1.1r10.img, and boot it from microSD card, but can't enter Debian Desktop environment. I wonder why? Please kindly reply me. Thanks in advance.

B.R.

Hi Marvin,

The Desktop environment should work out of box. What are you utilizing as a display(HDMI or MIPI LCD)? Are you getting anything on the display?

Hi Joshua:

      I am using HDMI monitor to connect to Maaxboard and can't enter Debian5 Desktop.

Hi Marvin,

Are you getting anything on your screen? Are any of the leds on the board turning on? What SD Card are you using? What are you using as a power supply?

-Josh

Hi Joshua:

1. Are you getting anything on your screen? 

    HDMI monitor is always black.

2. Are any of the leds on the board turning on?

    Yes. Debian5 can normally boot from microSD card.

3. What SD Card are you using?

   I am using "Team micrSD 500X 16GB", it functions well.

    https://24h.pchome.com.tw/prod/DGAG1C-A900987CE 

4. What are you using as a power supply?

   We bought this https://www.avnet.com/wps/portal/us/products/new-product-introductions/npi/avnet-maaxboard/

  The only power input is "USB Type C 5V/3A" , as describe in the  avnet-maaxboard's website.

This Maaxboard probably has hardware's defect or malfunction, or poor design or poor quality....? I still don't know about it.

Hi Joshua:

     I just download 02AndroidShipmentImage.zip and burn MaaXBoard-AndroidShipmentImage-SDcard-HDMI-V1.0.2r03.img to microSD card.

The result is the same, it also can't run to Android  desktop. Only u-boot can output a NXP image to HDMI monitor.

Hi Joshua:

     Following is the dmesg after boot, the kernel-4.14.78 drm and hdmi driver's output messages.

Everything seems to be O.K., except for "Unable to configure VS infoframe"?  It always is black screen on the HDMI monitor.

Hi Joshua:

$ git clone https://github.com/Avnet/maaxboard-debian-build

$ cd maaxboard-debian-build

$ sudo ./debian_build.sh -b rootfs -f ./board/maaxboard/maaxboard.ini

(But below errors occur:)

https://github.com/Avnet/maaxboard-debian-build

Connecting to 192.168.2.100:80... failed: Connection timed out.

failed: Connection timed out.

Retrying.

I still fail to build Debian5 image by myself because of the above error, is it possible to point the address of your Debian bsp repository to the external world?  

If it is, please kindly tell me how to modify "board/maaxboard/maaxboard.ini"? Thanks in advance.

Hi Marvin,

We are hoping to have this issue resolved by end of the week.

Apologies.

-Josh

Hi Joshua:

    O.K. I'm waiting for your good news. Thanks.

Best Regards,

Marvin

Hi Marvin,

This should be fixed now. Please let me know if you hit any further issues.

Thx,

Josh

Hi Joshua:

      Git clone from https://github.com/Avnet/maaxboard-debian-build and rebuild Linux kernel image are workable now.

But it still can't run in to Debian window desktop via HDMI monitor.

1. U-boot is calling maaxboard-dcss-hdmi.dtb as follows:

$ cat uEnv.txt

fdt_file=maaxboard-dcss-hdmi.dtb

console=ttymxc0,115200 console=tty1 fbcon=rotate:0

2. The following messages are hot-plugging in HDMI cable that connects HDMI monitor to maax-imx8mq board, the dmesg's output :
