With Himba's help, I got things running much better for my OMAP 1510 Innovator LCD driver U-Boot, but once the LCD comes up (drv_lcd_init finishes), the serial console output is switched off. I can still issue commands from my serial console, and have them take effect (like changing a status LCD or turning off the LCD backlight with mm.b), but can't see any more text output.

I tried commenting out

#ifdef CFG_DEVICE_NULLDEV memset (&dev, 0, sizeof (dev));

strcpy (dev.name, "nulldev"); dev.flags = DEV_FLAGS_OUTPUT | DEV_FLAGS_INPUT | DEV_FLAGS_SYSTEM; dev.putc = nulldev_putc; dev.puts = nulldev_puts; dev.getc = nulldev_input; dev.tstc = nulldev_input;

device_register (&dev); #endif

in common/devices.c, as when CONFIG_SPLASH_SCREEN is defined, CFG_DEVICE_NULLDEV gets defined, and would appear to reroute console output once assigned with dev.putc = serial_putc would now be dev.putc = nulldev_putc. However, this did not change the situation for me at all.

Any ideas on how to maintain the serial terminal? Take note that my driver is very very similar to cpu/mpc8xx/lcd.c, so I do not expect that coding that I did is disabling the serial terminal, but instead some other interaction in the code is doing this.

Thanks,
