Re: [microblaze-uclinux] error UART not defined


Michal
I'm still fighting the original error UART not defined problem and will be asking some additional questions soon, but..... I'm not sure disabling U-Boot will help either since I do need the image.ub file. However, to get through the night, as they say, let me understand this last suggestion. If one takes the following.... 

petalinux-dist/vendors/PetaLogix/common/common.mak

and edits the lines containing:

ifneq ($(BUILD_UBOOT),)
image: mkcramfs $(LINUXBIN) $(FSIMG) $(ELF_IMAGE) $(SREC_IMAGE) netflash_ver mkubimage mkubscript 
else
image: mkcramfs $(LINUXBIN) $(FSIMG) $(ELF_IMAGE) $(SREC_IMAGE) netflash_ver
endif

and edits it to:
image: mkcramfs $(LINUXBIN) $(FSIMG) $(ELF_IMAGE) $(SREC_IMAGE) netflash_ver mkubimage mkubscript 
image: mkcramfs $(LINUXBIN) $(FSIMG) $(ELF_IMAGE) $(SREC_IMAGE) netflash_ver
The /tftpboot directory, when the compile is complete, will have the image.ub file exactly as if U-Boot was run?
If this is the case, then why run U-boot at all? Understanding I have no experience yet with U-Boot and what it does. 

....thanks......Chris

Hi guys,



Hello Mak,

Just to clear something out:

image.ub --> is the linux kernel image and the root file system in
U-Boot format.

it was not created since you specified that you did not want it to be
created when you customized the platform settings in Menuconfig.

image.bin --> is the linux kernel image and the root file system in
binary format. this is the one you would use to boot the system up in
this case.

correct me if I am wrong. thanks.


yes, you are right. But it is no problem you can create it by hand.
It is easy. Go to petalinux-dist/vendors/PetaLogix/common/common.mak -> lines
428-460 -> remove ifneq and endif and you should get ub images without U-BOOT
build. Or just run line 442-449 with correct values.

Regards,
Michal

    You did disable u-boot, didn't you... That's why you won't receive
    any u-boot-doped binaries. The extension .ub stands for - U-Boot!


        I am confused with this. Is it that I am missing something while
        config or something has changed?



    Don't be... ;)
