got my KD20 succesfully upgraded to 21.02rc4 from NAND with ubifs-sysupgrade , but failed to load the entire kernel because in the uboot env is just 0x30000 (3.145.728 Bytes) given as loadsize, after change it to like 0x40000) it works without issues. (setenv load nand read.e 0x60500000 840000 400000)
shouldnt sysupgrade do that with fw_setenv beforehand?
