OMAP35X 6.15 WinCE BSP LCD backlight problems on Mistral Board

Eugen Feraru

Hello,

Building and loading a WinCe 6.15 BSP image via SD, onto the Mistral board, shows a dimmed Windows desktop, but the LCD backlight is off!

It appears that the LCD enable  works on the negative logic, as when the system seems to suspend, the backlight is suddenly on. When resuming the system, the light is off again. It should be the opposite.

 

Disabling the backlight driver did not seem to help. Please help.

    There are two different Mistral boards. EVM1 and EVM2 (little bigger and with more cinch for camera on left side). Which one do you have, and do you use the correct version? Do you use the prepared build or do you build an image yourself?

    If you use the wrong version on the board, you have these backlight issues.
