Re: [microblaze-uclinux] Re: [microblaze-uclinux] UDP packet reception triggers a hangup on the microblaze
Hi Bas,
that's new feature which we added some days ago for uart16550 support.
Just go to your hw design and use latest BSP - and generate libraries.
Everything should be fine.
And of course you can use U-Boot from my site too.
Both version works well. I use both of them.
Regards,
Michal
