New and old LCD problems with smartarm3250

New and old LCD problems with smartarm50

Because smartarm50 experienced a liquid crystal replacement, the early LCD module was a TFT-6862, and later the LCD module was a TFT-4238, the timing of the two LCD modules was significantly different, and even the clock polarity was different. The linux-2.6.27.8-smartarm3250_V1.05.tar.bz2 kernel is not well processed on the old LCD, resulting in the LCD dot not bright, and now has been corrected. Click the link below to download the corrected kernel. the kernel has added the LCD screen to the kconfig menu. Select the configuration based on your screen. Under the root directory there are two configuration files: config-6862 and config-4238, which correspond to the two LCD screens respectively.
