Unsupported node format error in Dmesg
noelpedro opened this issue · comments
Hi Ichiro, anythin obvious in my DTS node that may cause the unsupported node fomrat error?
[ 0.000000] OF: fdt: Reserved memory: unsupported node format, ignoring

size cell and address cells should each be 2?
Fixed it by writing =2, but now getting kernel panic.

This issue does not seem to be related to u-dma-buf.
Please check your device tree.
True, I Believe that memory region is also being allocated by the default ddr node generated by petalinux.
deleted the auto generated ddr node, but still got the error. Commented out my udmabuf node now I dont see the kernel panic. anything in my device tree udmbuf node that my be wrong?
For my system the reusable flag was causing the kernel panic, now I'm able to do 1GiB udmabuf and 1 Gb reserved memory region.
