booting issue with xo-1.75

[carcellelist]

Dear xo developers,

i received a xo-175 a few days ago and i got it to partially boot from the uart
interface with the serial adapter (using "boot" at the firmware "ok" prompt) but i get
stuck here :
...
[  647.362835] mmc2: no vmmc regulator found
[  647.370325] mmc2: SDHCI controller on MMC [sdhci-pxa.2] using DMA
[  647.381468] drivers/usb/core/inode.c: creating file '002'
[  647.392072] usbcore: registered new interface driver usbhid
[  647.401205] usbhid: USB HID core driver

Is anyone experiencing the same issue ? am i missing something during the boot ?

my best,
