I had the same experience :laughing:

maquefel commented 2 years ago

memory node with size and location dropped from u-boot.

They switched to patching dtb from boot0, so patched version of dtb should be used located in fdtcontroladdr, so now we are not loading dtb and booting like booti ${kernel_addr_r} - ${fdtcontroladdr}.

Can't say that i am happy with such an approuch, so i'll add memory node to linux dts later.

Updated boot0, u-boot, linux and README.
