FS#2320 - u-Boot OpenWrt 18.06.2 on sama5d31 Unimplemented compression type 3

after building 18.06.2 OpenWrt version and his nand flash u-boot (U-Boot 2017.03-linux4sam_5.8 (Jan 30 2019 - 12:21:02 +0000)) when u-boot try to uncompress lzma kernel image the following error is reached


Uncompressing Kernel Image ... Unimplemented compression type 3

 Uncompressing Kernel Image ... Unimplemented compression type 3

Checking into u-boot (make menuconfig) seems that lzma cannot be set , only LZ4 is provided.

Also the option to change compression type of the kernel do not work. I try to switch from default (gzip) to LZ4 but kernel uimage is always lzma compressed.

Could you provide some hint to unlock the situation ?

Another strange things is :

Error: ethernet@f0028000 address not set.
No ethernet found.

f0028000 is memory address of GMAC that is not provided in sama5d31 SoC but the curious is the next No ethernet found.

Does it mean that nor EMAC was found ?

Thanks in advance
