Trying to build linux for omap35x following README in patch download and Application Note 412 I have loaded CodeSourcery, and Logic Patches (and source for kernel and uboot from Logic patches download). After successfully patching u-boot and then trying to configure u-boot per the README file i get a "No Rule to make target 'omap3logic_config' " message.
I have not found arnything in FAQs or Discussion Group on this problem.
Below is the screen shot from the terminal. As I am new to linux perhaps I am missing some obvious step. Any help would be appreciated. Thank you.

As a follow-up to this question I see in the u-boot/include/configs directory that there are several possible .h files including "omap3_logic and omap3_zoom1 and omap3_zoom2. I am using zoom omap35x torpedo board. Perhaps I should use one of these. Please advise.

Using the omap3_logic_config reference seemed logical since this was the closest to the Logic documentation. Doing so led to a successful result. However, at the next stage running "make ARCH=arm CROSS-COMPILE=arm-none-linux-gnueabi- all" gave a long output ending with the following (screen capture):

Using an earlier version of CodeSourcery (2009q3-67 4.4.1) seems to allow me to get past this point. - FT

Frank,
That was the suggestion I just got from my Linux guru.
I hope that fixed it.

Richard,
Thank you for the confirmation. I've moved through the Application Note 412 up to Step 11.4 (Create a New U-Boot Envirnoment) which is aborting as shown in the screen capture below (steps 11.2 - 11.4):

I note that when I loaded U-Boot (step 11.3) i received a warning that the address in SROM was different from the address in "envirnoment" which I will look into. In the meantime if there is anything obviously wrong that jumps out please let me know.
One other thing I should mention is that at step 10.4.3 (Repackage the Root File System) I needed to enclose the -n argument in quotes ( "uboot ext2 ramdisk rootfs") in order to get mkimage to run. I am not sure if this is a problem but thought I would mention it as it also resulted in a difference in the output when I loaded uInitrd in AN412 step 11.4 where AN412 shows Image Name: as blank whereas my output shows Image Name: uboot ext2 ramdisk rootfs. Again, thanks for any help you can provide - |

One additional thing that I note is that after running the "bootm" command (see previous post) the system response for the kernel image is:
Load Address: 00008000
Entry Point: 000080000
versus the AN 412 example which shows:
Load Address: 80008000
Entry Point: 80008000
Do my addresses indicate a problem?
I re-made the uImage file and received following response to the "file" command:
Quote:
ftiernan@ftiernan-Latitude-2120:~/olfs/kernel/linux-2.6.32-logic$ file arch/arm/boot/uImage
arch/arm/boot/uImage: u-boot legacy uImage, Linux-2.6.32, Linux/ARM, OS Kernel Image (Not compressed), 661836 bytes, Thu Jun 28 15:28:39 2012, Load Address: 0x00008000, Entry Point: 0x00008000, Header CRC: 0x9141FA6C, Data CRC: 0x9B9A53A4
Which also differs from the expected response shown in AN 412 and contains the questionable addresses so I am wondering if this is an indication that something is wrong with my making of uImage.
Thanks for any suggestions! |

Richard,
You can ignore the last couple of posts as I have must have done something wrong with earlier makes of uImage. I redid it recently with the following result to a "file" command with the expected address:
Quote:
ftiernan@ftiernan-Latitude-2120:~/olfs/kernel/linux-2.6.32-logic$ file arch/arm/boot/uImage

ftiernan@ftiernan-Latitude-2120:~/olfs/kernel/linux-2.6.32-logic$
I now get the the Uncompressing Linux...........
Stage of the response to bootm
there is still something wrong as it seems to hang there and I still do not see "Hello World" but at least it is not aborting on bootm! I'll keep plugging away... |

I expect to see some output related to the startup of the kernel but there is nothing. Any suggestions or troubleshooting advice would be appreciated. |

Frank,
I'd recommend you use the Ask A Question system. It doesn't look like a lot of other suggestions are coming in.

Frank,
I looked into this for you and it looks like you don't have your bootargs set. You can set them up manually or use a script in the U-Boot env by typing the following at the U-Boot prompt:
run ramboot
You may run into the same errors I got after doing this one of them was that the /etc/init.d was not allowing root to run it. You will need to go back to the step where you mounted the ramdisk.img and change the file permissions by typing the following:
sudo chmod u+wx
Additionally, you may need to create device nodes tty2, tty3 and tty4
sudo mknod -m 660 tty2 c 4 2
sudo mknod -m 660 tty3 c 4 3
sudo mknod -m 660 tty4 c 4 4
Best regards, Steven Eckhoff

Thank you Steven, this worked!
In case it might be useful for others, here are the bootargs that worked for my setup:
Quote:
=> setenv bootargs display=15 console=ttyS0,115200 root=/dev/ram0 ramdisk_size=109000
=> saveenv

Thanks again for your expert help!
