It doesn't turn blank. I keep on seeing the penguin, but no login prompt. Fido and jethro seems to use slightly different u-boot versions. Recipes just seem to point to different versions, there are some patches but they are for different CPU. A bit better for the kernel, same version but different git revision. It will take me some time to get an idea how the recipes work and what are the differences between versions. I'll have to check in the tmp/work dir. Tomorrow there is a chance I'll get my serial cable and things may get easier. Again has anyone succeed to boot an imx28evk based board? thanks > On Mon, Dec 14, 2015 at 8:08 AM, justin chaise > > wrote: > > Hi, I am working with a board that is almost the same as the > imx23evk, the imx28evk sibling. > It seems that not all of our, MXS family, drivers were ported to the > newer kernels. > If fido booted and you saw a login on the lcd you may be in good shape. > > When you see the penguin logo that is the bootloader, u-boot, > initializing the hardware. > If the screen goes away after that; linux is not using or > initializing the lcd.
