Re: [microblaze-uclinux] Re: [microblaze-uclinux] UDP packet reception triggers a hangup on the microblaze
Hi Michal,
thanx, it's getting through the build process. The next stop is at
u-boot somehow I don't have the define CONFIG_STDINOUT_BASEADDR. Can I
follow
your procedure (http://www.monstr.eu/wiki/doku.php?id=uboot:uboot) to
make a good bootloader or should the one from the petalinux work fine?
greetings
Bas
