Hi Sinan, We have a very limited supply of boards, maybe one we have everything ongoing we could arrange for one. Is there anything I can provide so you could help me out a bit? I’m stuck with this hanging situation and I’m running out of idea why it’s not working…as it matches most of the old working uboot settings…
