RE: [microblaze-uclinux] Booting design from flash then FS-Boot, U-Boot, Kernel
Hi Ulrich,
Thanks once again. I will already do dos2unix for Kconfig file
which I copy .
Is it possible to you just send me the code which you run for Spartum 3A
Thanks
Deepak

yes, Just one small fix. You should do dos2unix conversion for removing
CR-LF
line ending.
