i have trying Installing Linux Qtopia on mini 2440 board. i have followed all the instrcutions from formatting nand , putting super vivi loading kernel image and rootfs_qtopia_qt4 files. after downloading i am getting the qt application on the board. when i see thru hyperterminal all the files are there. what is the problem how can this be sloved
What command you do invoke to run your Qt application on the mini2440?
I am not getting the Linux logo on the screen and the starting QT program is also not seen on screen
If you can see all the files on the target via hyperterm that suggests that that kernel and root filesystem has gone well. Did you have the Linux logo before you downloaded your Qt app? Did you make any changes to /etc/rcS ? Post the complete bootup messages, there might be a hint in there.
You should be able to start your Qt program from the terminal. What command would you use to do that?
@Giridharan U can run any qt app using ./filename -qws command over the terminal, as dave suggested post us the entire output and tuto u followed to load the system, which make us to give perfect solutions to solve ur query
thanks fo the reply I think the problem is on the display. There is no message. It stats with white background and the some thin lines comes and stays. On the display it is written as P35. is there any image file for this. I am using ZImage_x35. is this ok
Dear Giridharan, zImage_x35 will not work. Try zImage_w35. Visit this thread:- http://www.friendlyarm.net/forum/topic/5808 for LCD parameters and zImage link on that.
dear sandeep, Thanks for the reply. i used w35 image it worked but the touch screen is not working. how to calibrate and proceed.
calibrate is somewhere in config menu of Qtopia, or if you wanna use terminal, maybe there'll be file name ts_calibrate somewhere. (maybe /usr/bin/) Make sure all your setting, paths and filenames before and after installation is right, black screen with nothing appeared to me when I installed kernel incompletely.
I am not able to find touchscreen file the program stops at Touch Cross Hair to calibrate. how to proceed further
"program stops at Touch Cross Hair to calibrate" Did the program let you calibrate that 5 points of the screen completely and then stop working, or just open the calibrator and can't do anything? you said you can access terminal, can you open Qtopia with command ./bin/qtopia? Is the touchscreen worked? Can you use your mouse instead of touchscreen?
just open the calibrator and can't do anything. It doesn not proceed
further the message on the screen
TSLIB calibration utility
Touch crosshair to calibrate
wnen we press on cross haor ntohing is happening
Which command you use for calibrating? Could you tell me where did you get the rootfs image file? Wanna see it.
I solved it i used image S70 instead of A70 it got solved
I have compiled c program and trying to eexcute in termainal ./hello. it is displaying Illegal instruction what is the problem
Do a readelf -a filename.c (on the cross-compiled file and on your host machine) and show us what the last 10 lines say. Or readelf -A filename.c
Attribute Section: aeabi File Attributes Tag_CPU_name: "5T" Tag_CPU_arch: v5T Tag_ARM_ISA_use: Yes Tag_THUMB_ISA_use: Thumb-1 Tag_ABI_PCS_wchar_t: 4 Tag_ABI_FP_rounding: Needed Tag_ABI_FP_denormal: Needed Tag_ABI_FP_exceptions: Needed Tag_ABI_FP_number_model: IEEE 754 Tag_ABI_align_needed: 8-byte Tag_ABI_align_preserved: 8-byte, except leaf SP Tag_ABI_enum_size: int
mini2440 should say: Tag_CPU_arch: v4T What is the path to your compiler? A command something like: arm-linux --version might provide a clue.
It was good you provided more than 10 lines :)
arm-linux --version is not accepting sayuing command not found path is arm-linux 4.4.3/opt/FriendlyARM/toolschain is there anything extra need to be done
Your PATH is incorrect, check it again. see where you extract toolschain to.
