I did flash the AXFS rootfs with the following CommanderScript as well but it did not seem to help:
speed 100000
device R7S721001
rx 100
exec SetCompareMode=0
exec SetVerifyDownload=0
exec SetSkipProgOnCRCMatch=0
loadbin rootfs.axfs.bin,0x18800000
exit
Also, the u-boot command that I am using to boot is:
run xsa1 xsa2 xsa4; set bootargs console=ttySC2,115200 console=tty0 ignore_loglevel root=/dev/null rootflags=physaddr=0x18800000; fdt chosen; bootx 18200000 09800000
Where:
xsa1=sf probe 0; sf read 09800000 C0000 8000
xsa2=fdt addr 09800000 ; fdt memory 0x08000000 0x02000000
xsa3=qspi dual
xsa4=qspi single
The strange thing is that the kernel boots mostly, but hangs half-way. It does not complain about not finding a rootfs.
