Video Related

  • Make sure that PIN8 of SW6 switch is turned on(to make off-chip HDMI display and EVm LCD display work).
  • For Off-Chip HDMI display, on some TV's the image might be cropped(Few Lines(~15) on left and top might be missed), This is due to some TV's will do overscaling.If TV supports to disable this feature, then after disabling the video will be proper.
  • Some Flashes will be seen on LCD display during power cycle. After inserting tlc59108 module, you will see Flickers, change the venc timings suitable for LCD.Refer Video Driver User Guide for more details on changing the timings.
  • Off-Chip HDMI is working with only small lilliput display, samsung and philips TV, some models of Samsung may not work.


Hardware modification for Off-Chip HDMI to work with all TV's

Remove R267 and R578, and populate R264 and R579 with 10K registers


Hardware modification for 16-bit NAND

16-bit NAND is supplied with the EVM but the bus width selection switch is not populated on the EVM. By default, GPMC_D[12] is pulled down, hence corresponding to 8-bit NAND support. So, to support the NAND boot on the EVM (having 16-bit NAND), the following modification has to be done:

  • Pull up GPMC_D[12]: the resistor populated at R336 should be moved to R313

This will set BTMODE12 to 1, which is the required configuration to support 16-bit NAND.

USB Overcurrent on USB1 port:
Please use daughter board for USB1 support, refer to TI811X known issue section [1]


Ethernet Switch setting
For Connecting EMAC1 Phy

  • SW7.1 - On
GPMC and EMAC Pin Mux Selection
SW10.2 GPMC/EMAC Pinout connects to
ON GPMC
OFF EMAC
  • GP5[4] is by default low and not programmed
