C6A816X_EVM Graphical Application Launcher

Hi,

idle said:

When power on system was successfully startup, but I have got some error messages:

Error opening /dev/fb0: No such file or directory 

hwclock: can't open '/dev/misc/rtc': No such file or directory

Calibrating touchscreen (first time only)ts_open: No such file or directory

All system parameters was set by default. System booting from SD-card. But Graphical Application Launcher do not  display nothing.

These errors can be safely ignored for now.They are harmless and not related to the Matrix coming up.

To debug the issue, can you please try the following?

1. Have you hooked up HDMI from the board to the LCD panel that's shipped with the kit or to a different TV. If its a different TV, it may or may not support 720p60, which is causing this problem.
2. Log into linux and run "ps". Check if matrix programming is running. If it running then you should be able to see.
3. Check if the fbdev kernel module is present in the kernel. Run "lsmod" from the command prompt to ensure that vpss, hdmi and syslink are running.

If each of these are fine, then the software should be ok and should show the graphical output.

Hi!

1) I connect EVM HDMI output to TV Phillips 32PFL7803 (it is supported resolution 720p, 50, 60Hz ... ), and on screen was: "No signal". LCD panel was not shipped with the kit, but it was show image from PC hdmi output.

2)  ps output: PID 1165  is the "matrix programming"?

3) "lsmod" output: there are vpss, hdmi (TI81xx_hdmi) and syslink, but ti81xxfb is the same as fbdev module?

From your logs, it appears that all drivers and software are running fine. Let me check with other experts on how to debug HDMI further and get back to you.

Hi, Siddharth Heroor!

Do you have any new information for me? I try to boot my system from NFS with two different kernel image (uImage and uImage-c6a816x-evm.bin without compiling) and root filesystem.  Setting took from here http://e2e.ti.com/support/dsp/integra_dsparm/f/625/t/103329.aspx.

Thank you.

Ok. May be this is some mechanical damage on the board, beacuse SATA connectors were placed with angle of 30 degrees on the board then I saw it.
