Hello, everyone. I was finally able to install some out of the box working embedded linux on my mini2440. The thing now is that I have only command line prompt and I woul like a graphical environment, is that possible with Pengutronix? How to build my own programs/packages with this BSP? Thank you very much! Javier
I forgot to tell that I have a 1Gb mini2440, with W35i LCD . Also..wich one is the parameter for this display?? 0tb, 1tb ?? I have tested all and neither of them worked. Merci Beaucoup!
Did you build the "ptxconfig" or "ptxconfig.qt" configuration? With "ptxconfig.qt" you will get a small qt based demo app. which starts automatically. The W35 display should work out of the box. But the "i" means it uses an embedded touchcontroller. This feature is still untested at my side. BTW: refer the BSP documentation: the "w35i" is type 6. So try with "mini2440=6"
Thank you very much Juergen! I would like to know if there is any way to compile my own source code/packets like with bitbake. I would like to try to compile any desktop environment such as SATO, or qtopia. Is there any already built for Pengutronix? Thanks again! Javier
PTXdist is "rule file centric". If you want to add your own code to be included in the build process try to run the "ptxdist newpackage" command. It creates skeletons of new rule files which helps you to add your own code.
Thanks! Juergen::: I, checking the guru guide for Pengutronix! ;)
Hi Juergen, By using Peguntronix BSP(new release 2015) ,I have successfully build Linux kernel image 3.16,root filesytem,barebox image. But the issue with my LCD display is not working. I am using w35i LCD display. I have edited this file Minicom / edit /env/config bootargs =".............mini2440=6tb" [ 6 is the no.for w35i LCD display as mentioned in manual] after that i have booted .But didn't work Pls help me to solve this issue Regards, Sudhakar.g
There's currently no support for the "w35i" variant in the Mini2440 BSP. Only for the "w35" variant. BTW: what does "LCD display is not working" means?
Top of page 21 in the QuickStart guide. 6 w35i: 3.5” TFT + touchscreen (Sharp LQ035Q1DG06) So, this is an error? IE, there should be no i after the w35
Hi davef, you are right. The display (signal timings etc.) is supported. But not its special type of control. I guess sudhakar_G's display is already working, but due to the lack of backlight he cannot see anything...
Hi davef, Thank you for your reply.So mini2440 BSP doesn't have support for W35i LCD. One more thing sir,I want to learn how to drive the peripherals[LED,GPIO,ADC,UART,PWM,USB,LAN] on the Board.Can u pls help me how to start? what are the files/docs i need to refer to write my own drivers.
That appears to be the situation. But, before you give up: http://www.friendlyarm.net/forum/topic/3366 To quote: Hi deltaT to control backlight, just type "echo 0-127 /dev/backlight-1wire" on the console. it is very easy. mindee unquote. Is it a backlight or 1-wire problem? sudhakar_G, I am sure there has been discussion about "your" problem, maybe create a new thread to see if someone has come up with a working solution. Something like " w35i display problem". People who would make their own kernels from scratch would have to address this problem. Kernel modules. With a lot of help I managed to make a SPI kernel module. I will probably never do it again! The Linux Kernel Module Programming Guide.pdf Linux Device Drivers.pdf
