can you please help in this regard? I am not sure what wrong i am doing here. i have yocto installed properly. As you can see the folder u-boot-altera-dis-1.0-r0 does not exist for me when i run bitbake u-boot
.

What recipe-image are you trying to bake? can you put the bitbake argument that you used?
You have another issue regarding sysroot_populate task it looks like a tar miss behavior/configuration if you don’t solve this issue before you will not be able to create a sysroot at all so you will need to focus on this issue if you want to create a loadable image, if you don’t mind and you just want to create u-boot image you could try

$bitbake -f virtual/bootloader

If you want to see the u-boot code within your tmp/work try

$bitbake -f -c configure virtual/bootloader

hello,
thanks for getting back, the argument that i used was bitbake virtual/bootloader . i followed the procedure on the link https://rocketboards.org/foswiki/Documentation/GSRD131QspiBoot#WriteQSPI.

pardon my ignorance but i am very new to this. how do i fix the sysroot issue? i have installed all the necessary packages except for the ia32-libs . i run into issue when i try to install this. i looked all over and couldnt find a way to install that package.

just came across this below link that says i need to downgrade to ubuntu 12.04. i am currently running 16.04. i wonder if its still the case.

based on the comments it looks like there is an issue with tar version… do you already tried to downgrade tar? https://community.intel.com/t5/Intel-Makers/Bitbake-error/td-p/504553#.XxcNpeFAhI8.link
