thanks for your answer, the odroid m1 is working well with the ssd disc.
ISSUE with the odroid m1 image I built today after this up date, the emmc module boot on the m1 but I can read on the bottom left on screen :
Can't open (/proc/kcore).
a few second later a second message appear
[eth0] PXE autoconfiguration failed
I don’t know how to configure petit boot.
