Has anyone been able to use the 7" screen with a mini210? What changes to the kernel did you have to do as I can't seem to find any references to building with a 7" screen. I would like have the bigger screen size with my design as the 5" looks a little small in the enclosure I have for it. Dave...
before burn the kernel zImage, define LCD_TYPE=A70(or S70 in the FriendlyARM.ini please try
Thanks Mindee, I'll have a go tonight.
Hi Mindee, I tried this with both A70 and S70 as the settings in the INI file. A70 would not boot just giving a beep and the LCD being white. S70 would beep and the LCD was white but the LED's indicated flashing but after done and try to reboot, I get the linux logo briefly appear on the LCD and then it resets in a loop. The 7" LCD I have is configured for 1-wire touch and works with the Mini6410 that I have. I am connected to LCD1 connector on the PCB. Anything else I should look at?
Hello Dave, Are you running mini210 on battery?
Change the text to A70 or S70 (whichever you have - s70 is in a light plastic shell with a small PCB across the back. A70 is in a panel mount bezel with full size PCB for mechanical support) in two place. Near the top of the file - is should have the name of your previous display - so that Superboot can display any directions and a progress bar, and in the zImage file name for your kernel.
Make sure the 7" kernel is in the directory.
@Pratik. Not yet. The support PCB for the module is in design just now. I'll post here in the forum when it is ready and the prototype tested. @TheRefnirps. Doesn't work. I have the A70 PCB and it just gives me a white screen that clears after a few seconds indicating that it did not configure. There is no apparent 7" driver settings in the kernel configuration like we had with the Mini2440, Mini6410 etc. There is only a setting in the INI file when you install the OS to the NAND flash but it won't work.
OK. I got it to work. Seems that the Mini210 doesn't always boot correctly when flashing but after a couple of attempts it worked. The display looks great on the 7" and just as fast as the 5" but the touch screen performance is far less. With the 5" I can get response from a finger but with the 7" I need my nail to make it work unless I apply more force. This is a real pity as I was hoping to use the bigger LCD for this project. Cheers Dave...
