Error: Compiling uClinux with Frame Buffer (altfb.c)

[Altera_Forum]

Hi, 

 I have a Nios II Embedded Evaluation Kit and wanted to try uClinux with frame buffer on it. (Followed the instruction on http://www.nioswiki.com/operatingsystems/uclinux/framebuffer). The SOF and PTF files are for the Standard System (http://www.nioswiki.com/nios2embeddedevaluationkit)  I got the following error message refering to altfb.c:  /home/rask/nios2-linux/linux-2.6/drivers/video/console/fbcon.c: In function `fbcon_init': /home/rask/nios2-linux/linux-2.6/drivers/video/console/fbcon.c:1071: warning: statement with no effect /home/rask/nios2-linux/linux-2.6/drivers/video/console/fbcon.c:1073: warning: statement with no effect /home/rask/nios2-linux/linux-2.6/drivers/video/console/fbcon.c: In function `fbcon_set_disp': /home/rask/nios2-linux/linux-2.6/drivers/video/console/fbcon.c:1346: warning: statement with no effect /home/rask/nios2-linux/linux-2.6/drivers/video/console/fbcon.c:1348: warning: statement with no effect  CC drivers/video/console/bitblit.o  CC drivers/video/console/fonts.o  CC drivers/video/console/font_8x16.o  LD drivers/video/console/font.o  CC drivers/video/console/softcursor.o  LD drivers/video/console/built-in.o  LD drivers/video/display/built-in.o  CC drivers/video/altfb.o /home/rask/nios2-linux/linux-2.6/drivers/video/altfb.c: In function `altfb_mmap': /home/rask/nios2-linux/linux-2.6/drivers/video/altfb.c:87: warning: assignment makes integer from pointer without a cast /home/rask/nios2-linux/linux-2.6/drivers/video/altfb.c: In function `altfb_dma_start': /home/rask/nios2-linux/linux-2.6/drivers/video/altfb.c:191: error: `na_lcd_sgdma' undeclared (first use in this function) /home/rask/nios2-linux/linux-2.6/drivers/video/altfb.c:191: error: (Each undeclared identifier is reported only once /home/rask/nios2-linux/linux-2.6/drivers/video/altfb.c:191: error: for each function it appears in.) /home/rask/nios2-linux/linux-2.6/drivers/video/altfb.c: In function `altfb_probe': /home/rask/nios2-linux/linux-2.6/drivers/video/altfb.c:253: warning: passing arg 3 of `dma_alloc_coherent' from incompatible pointer type make[4]: *** [drivers/video/altfb.o] Fehler 1 make[3]: *** [drivers/video] Fehler 2 make[2]: *** [drivers] Fehler 2 make[1]: *** [sub-make] Fehler 2 make[1]: leaving directory '/home/rask/nios2-linux/linux-2.6' make: *** [linux] Fehler 1    Could anyone help me at this one?  Thank you in advance.  D.

Please try this design and select "NEEK" platform in kernel config.

Thank you Hippo. 

 As for frame buffer, your design worked out. Unfortunatly I got an error refering to atkbd.c:  altps2 : base 88001420 irq 9 mice: PS/2 mouse device common for all mice ads7846 spi1.0: touchscreen, irq 4 input: ADS784x Touchscreen as /class/input/input0 TCP cubic registered NET: Registered protocol family 17 RPC: Registered udp transport module. RPC: Registered tcp transport module. Freeing unused kernel memory: 1664k freed (0x20c000 - 0x3ab000) Shell invoked to run file: /etc/rc Command: hostname uClinux Command: mount -t proc proc /proc -o noexec,nosuid,nodev Command: mount -t sysfs sysfs /sys -o noexec,nosuid,nodev Command: mount -t devpts devpts /dev/pts -o noexec,nosuid Command: mount -t usbfs none /proc/bus/usb atkbd.c: keyboard reset failed on altps2.0  mount: mounting none on /proc/bus/usb failed: No such file or directory Command: mkdir /var/tmp Command: mkdir /var/log Command: mkdir /var/run Command: mkdir /var/lock Command: mkdir /var/empty Command: ifconfig lo 127.0.0.1 Command: route add -net 127.0.0.0 netmask 255.0.0.0 lo Command: cat /etc/motd Welcome to  ____ _ _  / __| ||_|   _ _| | | | _ ____ _ _ _ _   | | | | | | || | _ \| | | |\ \/ /  | |_| | |__| || | | | | |_| |/   | ___\____|_||_|_| |_|\____|\_/\_/  | |  |_|  For further information check: http://www.uclinux.org/  Execution Finished, Exiting  Sash command shell (version 1.1.1) /> atkbd.c: keyboard reset failed on altps2.0  Due to using the keyboard won't work.  Have you some advice on this one?  Thanks.  D.

It doesn't matter. Or you can connect a ps2 keyboard. You can still run nano-X if you configure it to "no keyboard", make user/microwin_clean; make .

Hi Hippo,

Hi mmkaya 

 I've just had exactly the same error while trying to make a uClinux image for DE2 board, but adding microwindows. I've followed the configs mentioned on nioswiki.com/OperatingSystems/UClinux/FrameBuffer Did you finally succeed to do so ? Hope you can help me Thank you  Flo

[Altera_Forum]

Hi Flo, 

 Yes,I have succedeed to run compiling after changing something according to other entries on the internet.It was six months ago so I can not remember the solution of error exactly.But I can say you can find the solution from google as I have done.   If you cannot find any solution, give a me a word. I can make a try to that issue.   Best Regards

[Altera_Forum]

Thank you mmkaya, 

 Actually I didn't found any solution from google. I've succedded by changing the name of the VGA controller in the SOPC Builder in Quartus : VGA_0 --> vga_controller_0 So the variable na_VGA_0 which was created becomes na_vga_controller_0 and then it works fine.  Best regards
