Linux/AM3358: Uboot displaying to 16x2 Character LCD

Hi Gary Simmons,

Its not usual to have a 16x2 character LCD along with u-boot or kernel in general.
With little bit of search, I could find HD44780 LCD has linux driver.
So, you can do the following :

1) Get HD44780 LCD or a similar one with Linux driver support. If there is no support for your LCD, you may write a driver for it.
2) Interface the LCD with your board and integrate the code in linux. Test it on console.
3) Once you confirm its working, you can integrate the same code in uboot.
4) This way, from uboot you can write messages while its powering on.

Have a look at the below links for your reference :
